Ensuring Your Car’s Safety Features Are Well Maintained

July 21, 2022 by Denver Express Car Care

Are you an old car enthusiast? There’s something nostalgic about glancing into an old car, imagining all the places it’s seen in its lifetime.

But glance inside a vehicle made in the 50s or 60s, and you’re also likely to see something missing: Safety features.

Car safety features have advanced since cars were first introduced in the market. In the 1930s, new safety improvements included all-steel bodies and hydraulic brakes. The 1950s brought on seat belts and padded dashboards. The 1990s made airbags standard equipment.

Today we take many modern day safety features for granted. When was the last time you thought much about airbag functionality?

But it goes beyond that too. Every single system inside your vehicle has been adapted with your safety in mind. Brake advancement, improved suspension, even emissions standards have been designed to make your driving experience safer while creating a better world as well.

Yet every single one of these safety features needs to be well maintained in order to function well when you need it most.

Ensuring Your Car’s Safety Features Are Well Maintained

What are some of the most important safety features?

Airbags

What started out as a simple safety feature to protect the driver has become a huge part of every vehicle’s overall safety strategy. Most new cars today will have a minimum of six airbags in place. Newer vehicles work to improve functionality, and offer as many as ten airbags or more.

While they aren’t perfect, they do more good than harm. The IIHS found that front airbags reduce driver fatality by 29 percent, and front-seat passenger fatalities by 32 percent.

While they are an excellent feature to have in case of an accident, things can go wrong over the years. Airbags are sometimes subjected to manufacturing defects, which can cause lack or improper deployment. Manufacturers are required to issue recall alerts as soon as they notice a problem. Fix it quickly if you hear of a problem.

With airbags in multiple places throughout the vehicle, the technology is also becoming more sophisticated to measure the weight and position of the seat. These systems are designed to adjust deployment to minimize injury.

The suspension system

The suspension includes the steering, wheels, tires, shock absorbers, struts, and many other components linking it all together. While a vehicle may come out of the factory with a tight suspension, everyday driving can start to whittle away at how all the pieces fit together. Every bump, dip, and uneven surface you drive on has the potential to damage the suspension system:

Broken springs
Damaged struts
Leaks in the shock absorbers
Wheel alignment issues
Uneven tread wear

While some of this is beyond your control, some are avoidable. This is where regular maintenance comes into play.

Start by getting familiar with your owner’s manual. It will establish guidelines for how often different components need replacing, or systems need to be repaired. Schedule maintenance items regularly, and be proactive in how often you seek regular maintenance visits. You can do things like:

Have the wheels aligned
Rotate tires regularly
Change out fluids timely
Maintain proper tire pressure

Regular service is the key to prevention.

The braking system

The brakes are one of the most important safety features on your vehicle. Without them working effectively, you put yourself, other passengers, and those around you at risk.

The braking system is exposed to a significant amount of friction and heat. Every time you step on the brake pedal, it adds energy through the brake pads and rotors, eventually onto the wheel itself. Common issues include:

Worn brake pads
Worn rotors and calipers
Leaking or low brake fluid

Aggressive driving habits will exacerbate these conditions. Ignoring a good maintenance schedule will also allow repair work to go unchecked longer, potentially putting more of the brake system at risk. To keep them in good working condition:

Have the brake system inspected once a year or every 12,000 miles. This gives a mechanic the chance to look at brake pads and rotors, and ensure it’s all working well.
Replace brake fluid every 25,000 miles or so.
Bleed brake lines as needed to remove air and dirt.

In modern day vehicles, antilock brakes (ABS) also aid in emergency situations. If you remember your instructor at driving school teaching you to pump the brakes during an emergency stop, ABS handles that process for you. It electronically pumps the brakes when it detects the wheels not responding as they should in an emergency. Electronics can do so more rapidly than you can, providing more assurance of coming to a complete stop. It is crucial to have this inspected regularly, to ensure it’s functioning properly and will respond in the event of an emergency.

Electronic stability control

In addition to ABS, electronic stability control (EBS) was enacted in 2012 to help keep the vehicle moving in the direction you’re steering. It’s a more complex system relying on both ABS and traction control for results.

The EBS sensors also measure sideways motion and steering angle to ensure stability. If something happens to your vehicle and the sensor senses the vehicle isn’t moving in the direction of your steering inputs, it uses every tool possible to return the car to its intended position. While it’s not foolproof, it does a pretty good job of keeping your vehicle under control in most situations. If this isn’t working correctly, your vehicle is at greater risk.

Is it working the way it should? Diagnostics can help determine if something is wrong with the control system, and make adjustments as necessary.

Are your car’s safety features well maintained?

The easiest way to ensure they are is to schedule a maintenance inspection today. Through diagnostics and inspection, we can determine where problems may lie, and ensure every system is in good working condition. We can help put a schedule together for better understanding on repair and replacement expectations, giving you a chance to add them into your budget.

Catalytic Converter Theft – What It Means To Your Car

July 18, 2022 by Denver Express Car Care

Have you heard talk in the media about catalytic converters lately? It’s not a lifestyle piece about what they do for your car. Chances are they’re talking about catalytic converters because of their increasing theft rate.

A recent study shows as of June 2022, there have been more than 26,000 thefts this year, an increase of more than 33 percent from this time last year.

Catalytic converters are an expensive part that are easily removed and stolen. What does a catalytic converter do for your car, and why are they being stolen? Read on. We have the answers you’ll need to keep your catalytic converter safe.

What is a catalytic converter

A catalytic converter is part of your vehicle’s exhaust system. While they come in different shapes and sizes, they are usually about the size of a loaf of bread. You’ll find the catalytic converter in the exhaust system located somewhere between the engine and the muffler. They need high heat to function, so they’ll be located as close to the engine as possible.

The catalytic converter’s job is to convert harmful exhaust pollutants into something less harmful. Through a chemical reaction, toxic hydrocarbons, carbon, monoxide, and nitrogen oxides are converted into carbon dioxide, nitrogen, and water vapor. Though not perfect, the EPA still commends the use of catalytic converters as one of the top inventions so far in the quest to make our air supply cleaner.

Catalytic Converter Theft - What It Means To Your Car

Why is catalytic converter theft on the rise

People steal catalytic converters for money. They contain three metals that aid in production of the chemical reaction needed to make pollutants less toxic: platinum, palladium, and rhodium.

The prices of each of these metals have risen steadily over the past decade to make them valuable enough for thieves to take. Platinum, for example, was just above $100 an ounce, moving to an all-time high of over $2,000 an ounce in 2008. It’s settled to around $1,000 today, which still leaves a heavy profit margin to anyone taking it for profit. Because of the value, junkyards are more actively collecting catalytic converters, and have even gone so far as to advertise “mail-in” campaigns making it easy to profit with few questions asked.

States around the US are now passing laws to make catalytic converter purchases traceable, and require proof of ownership when people try to sell them. Without the anonymity protection, it should help reduce theft. But until then, it’s important to know how to protect yours, and what to do if it’s stolen.

Can you drive a car if the catalytic converter has been stolen?

As a general rule, you can drive a car without a catalytic converter. It’s the catalytic converter’s job to lower emission levels and toxic fumes being released into the environment. But it won’t hurt the engine if it’s not in place.

That said, it’s illegal to drive without a catalytic converter in place. That means you’ll fail an emissions test if you don’t have one in place.

You’ll also notice a difference in the way your car performs.

Without a catalytic converter, the oxygen sensors will not operate within the designed range. That sends engine fault codes to diagnostics, engine performance will suffer. Diagnostics will receive a signal from the sensors to change the oxygen mixture to try and reduce emissions. You’ll likely see the check engine light with trouble code P0420.

You’ll notice a reduction in power every time you take your vehicle out on the road for a drive. Without the proper fuel and oxygen mixture, the engine will sputter as it tries to operate. You’ll notice this hesitation each time you take it out.

Your fuel economy will also be compromised, causing you to pull into the gas station more often. Because it impacts the fuel/oxygen mixture, it will push more fuel into the engine trying to accomplish the same action with new requirements. This results in more emissions production and less fuel efficiency.

The exhaust noise will also be louder and raspier without it.

Your car will definitely alert you to the problem.

How to prevent your catalytic converter from being stolen

While the good news is states across the US are putting laws into place to thwart criminal activity, it hasn’t stopped thefts from occurring. It’s harder to instill new laws onto older parts and technology, so it may take a while for rules and policies to catch up.

Until that time, there are things you can do to protect your catalytic converter and reduce the risks of having it stolen.

Catalytic converter replacement can typically cost thousands of dollars, depending on the vehicle. Some high performance vehicles may even have two catalytic converters in place, increasing the replacement cost.

Luckily, there are things you can do to help protect your car’s catalytic converter.

Park indoors if possible. If you have a garage, use it. It’s the easiest way to deter criminals from destructive behavior.
Park in a well-lit area. Thieves are less likely to work on a vehicle in a well-lit area, in view of anyone who passes by. A well-lit area with abundant traffic around the location pushes any would-be thief to another location.
Look for video surveillance. Some places make it well known the area is watched. Thieves want anonymity. If they know they might be observed and recorded, they’ll look for easier targets.
Consider getting your catalytic converter etched. Many police departments and some auto shops are now etching your license plate number onto the catalytic converter. This will tie any purchase back to the particular theft, and help stop more thefts in the future.
Have anti-theft devices in place. You can have installed shields that make it more challenging to steal. While not a perfect plan, with little evidence of how effective these are, if you live in a higher crime area, this may be worth trying.

Have you ever had your catalytic converter stolen?

Gas Saving Tips For Your Summer Travels

July 10, 2022 by Denver Express Car Care

How fuel efficient your car was even a few short months ago wasn’t that big of a deal. When gas prices were low, a swing of 5 to 10 miles per gallon barely registered in your mind.

Yet now, gas prices are rising … drastically. You notice it every time you pull into a gas station and fill up your tank. It’s difficult watching your final cost rise significantly upward, knowing there isn’t much you can do. Gas saving tips you read online never really amount to much … Do companies really think trading your car in for an electric car will save you money? Not when the average price of a car just rose beyond $47,000?

If your summer plans include road tripping, you want real gas saving tips you can use right now, with the car sitting in your driveway. Luckily, there are many things you can do that won’t break the bank.

Let’s start with the reasons why your car’s losing fuel efficiency

Sure, you can save a little bit of money by tracking gas prices with your favorite app, but that amounts to a few cents each fill up. The same applies to paying with cash.

Gas is an important part of keeping your vehicle fully operational. Have you ever purchased cheap gas and noticed your car ran rougher as it moved through the system?

The quality of gas is equally important. We suggest finding a reliable source that’s convenient for your lifestyle. Then use that source every time you fuel up. Do they have a loyalty program? This is the time to use it.

Depending on where you go on your summer road trip, you can sometimes find the same source along your drive. Many consumers use Costco for gas as well as other lifestyle choices. You can map out the best places to stop based on where a servicing station is convenient. It also works well if you need to pick up a few food items when arriving at your final destination.

While you can save some cash this way, it won’t make a huge dent in your fuel bill. This is when it comes time to ensure your car is in top condition, to ensure it’s using fuel as efficiently as possible.

Air filter

An engine needs both fuel and air to power the engine. Without the proper air supply, it won’t operate correctly. If the engine isn’t taking in enough air, it compensates for it by adding more fuel to the mixture. It will take more fuel to travel at the same speed.

This is why it’s vital to ensure the air filter is clean and capable of allowing a proper air stream into the engine. Clogged air filters are especially common in older cars that still rely on carburetors. While most manufacturers recommend replacing your air filter every 15,000 to 30,000 miles, it’s a good idea to check it regularly and replace it as you notice changes.

Fuel filter

A fuel filter blocks contaminants in the fuel supply, preventing them from traveling throughout the engine where they can cause harm. One of the biggest places contaminants can hamper fuel efficiency is by damaging fuel injectors. It can also lower fuel pressure, which further compromises your engine.

As your car ages, manufacturers suggest replacing a fuel filter every two years or 30,000 miles, whichever comes first. Check with your owner’s manual to follow recommendations. If you suspect a dirty fuel filter, bringing it in and letting a mechanic inspect it will ensure all parts of your fuel system are working as designed.

Fuel injectors

One of the most common reasons for a drop in fuel efficiency is a dirty fuel injector. Fuel injectors are tiny nozzles that spray fuel into the engine cylinder. This spray system must work precisely to mix with the air supply at the right time. Without it firing properly, it disrupts the fueling process.

When fuel injectors become dirty or clogged, the fuel spray is anything but precise. In some cases, the fuel injectors can be cleaned. Other times they may need replacing to ensure a proper spray pattern. Fixing the problem early will prevent it from escalating and damaging other parts of your vehicle.

Oxygen sensors

Today’s modern cars use an oxygen sensor to measure how lean or rich the exhaust gasses are as they exit the engine. These sensors register the results, then send a message to the computer system to adjust the amount of fuel that enters the engine.

When an oxygen sensor is dirty, it can lead to an inefficient amount of fuel entering the engine. Some estimate that fuel economy can be lowered by as much as 40 percent.

A faulty oxygen sensor is one of the more common reasons the check engine light will illuminate on your dashboard. It’s a good idea to bring your vehicle in anytime a light illuminates. A faulty oxygen sensor is an easy, affordable fix, and will help keep your fuel economy in check.

Tires

Low tire pressure can be a common occurrence as you drive on scorching hot roads. It’s also a common cause of lowering your fuel efficiency. Underinflated tires have more roll resistance with the road. It creates drag as you drive and lower the fuel economy over time.

Luckily, it’s also one of the easiest to fix. Pay attention to the dashboard. If it illuminates low tire pressure, inspect your tires for any signs of weakness. You should also check your tire pressure and fill it up with air as needed. Because tires can have a major impact on safety, especially as you road trip, it’s essential to pay attention to this throughout your trip.

Alignment

No matter how well you drive, you can’t avoid potholes, bumps, and other road hazards all the time. Each bump impacts your wheel alignment, and if it no longer sits straight, it’s costing you money at the pump.

Just like low tire pressure, a poorly aligned wheel creates resistance as it travels down the road. This continual pull hurts fuel economy too.

Now’s the time for a little TLC – before your road trip

With both your safety and fuel efficiency at stake, scheduling a maintenance visit before your next road trip just makes sense. You’ll stop any potential repairs from escalating, and ensure your vehicle is as efficient as possible.

It’s the best gas saving tips we can give.

Should You Consider a Transmission Rebuild?

July 4, 2022 by Denver Express Car Care

Your vehicle’s transmission is a vital part of operation. Without it, your car won’t go.

If your transmission has problems, it can be a safety hazard. Imagine getting in a situation where your car won’t change gears, or suddenly does as you’re driving down the road.

When you notice a transmission problem, a mechanic will inspect it and find what’s causing the issue. It might be a minor repair, or it could be more serious. That’s when you’re likely to have to make a decision: should you consider a transmission rebuild, or is it time for a new one.

Understanding a transmission

Think of a transmission as a car’s gearbox. If you compare it to a bicycle, it would consist of a gear shifter and chain mechanism.

The transmission components are mounted to the engine compartment so the gear and chain system can effectively convert combustion power from the engine into physical energy.

Fuel is ignited in the combustion chamber. As fuel ignites, it uses the heat to push pistons up and down in the engine cylinder, spinning the crankshaft. This crankshaft is what’s used to move the wheels.

Should You Consider a Transmission Rebuild?

It’s the transmission system’s job to ensure this energy force is kept under control. The transmission ensures energy is sent to the wheels at intermittent levels, depending on the speed you’re traveling at. Without it, it would be difficult to start and stop your car.

A transmission changes gears as the vehicle moves through different speeds. As you push down on the accelerator, let up and apply the brake, the transmission adjusts so that the engine’s revolutions per minute (RPMs) are kept relatively low. This provides better fuel consumption, and ensures the energy process doesn’t overload the engine. Think of it as a harnesser of energy, making the entire process work safely and efficiently.

Everything works well. Until it doesn’t.

What is a rebuilt transmission?

Transmissions are one of the most complex systems that make your vehicle operate. When something goes wrong with the transmission system, the repair process can escalate fast.

While mechanics will speak of a transmission as if it were one part, it’s actually a series of over 800 different components, each with its own unique make and model. Each part can be repaired or replaced. It’s a time-consuming and expensive process. Even for a highly trained mechanic, it takes time to ensure the right pieces are fixed, and the entire system is efficient once it’s put back together.

Inside a transmission are several major components:

Gear set – this allows the forward and backward motion.
Hydraulic system – transmission fluid moves through the system to help control gear movement. It helps with lubrication, cooling, and shift control.
Seals and gaskets – these components ensure lubricant stays where it’s supposed to be without leaking.
Pump and turbine – the engine and transmission work through a series of three fans, spinning as fluid is pushed through the system.
Throttle cable – this monitors speed and throttle position of the transmission to help determine the proper time to shirt.
Computer – modern day vehicles use a computer to control the process through a series of sensors.

A transmission rebuild would include working on any one or more of these components. If any part is damaged or worn out, the components would be in need of repair. It includes replacing a series of parts rather than replacing the entire transmission.

Rebuilt transmissions can involve major overhauls. It can include replacing several parts or systems within the transmission rather than installing a brand new one.

What happens during a transmission rebuild?

When a mechanic rebuilds a transmission, it involves removing the transmission and completely disassembling it. Each piece is inspected for damage or wear, and a decision is made on whether to keep it or replace it. If it’s kept, it’s cleaned and used as the system is being rebuilt. Clutches, seals, gaskets, and any other easily worn items will be evaluated during this process as well.

Why are transmission rebuilds popular? Because a rebuilt transmission can be considerably less expensive than replacing the entire system. Even a rebuilt transmission can cost several thousand dollars, depending on the problems. It’s a way to keep the costs as low as possible while bringing your vehicle back to drivable condition.

There is a break-even point where a transmission rebuilt and installing a new transmission meet. As parts and labor creep upward, there’s a point where it makes more sense just to replace it. A reputable mechanic can help determine that and make suggestions along the way.

Research shows that transmissions tend to fail between 80,000 and 150,000 miles. As you approach that mileage, you can start asking yourself questions.

How often do I bring the vehicle in for routine maintenance?
What problems have I had in the past?
How long do I plan on keeping this vehicle?

These questions can help you decide the best course of action. If your transmission has a history of problems, needing repair work frequently since you purchased it, it may point in the direction of replacement. If it’s never given you any problems before, rebuilding the transmission may be the solution.

Some common indicators of needing a transmission rebuild

Problems with your vehicle rarely occur instantaneously. Instead, you’ll start noticing problems build over time.

Transmission slipping – you’ll notice regular and sudden changes with gears shifting when it’s not expected. It might make a humming noise. It often happens with low transmission fluid levels, or lack of maintenance. The worse it gets, the more the gears are damaged. Too much damage would require a new transmission.

Gear shifting problems – your car won’t go without the ability to shift gears. When this starts to fail, you’ll notice it in several ways:

A jerking sensation as it moves between gears
Shifting without reason
Falling out of gear while driving
Hesitation before engaging

Burning smell – any burning smell should be checked out right away. It’s a sign of a component failing. The sooner you find the problem and fix it, the less at risk you are of the entire system collapsing.

Fluid leak – transmission fluid is a red color. If you notice it darkening, or leaking anywhere from the system, you’ll have cooling issues. Continuous leaks can result in low levels of transmission fluid, which means it’s not running through the system at optimal levels. It can damage a series of components.

Do you have transmission problems?

Whether a transmission rebuild is in your future, or a full replacement is necessary, it starts with a full inspection. Bring your vehicle in today, and we’ll help you make an informed decision.

5 Simple Maintenance Tips For Making Your Car’s Tires Last Longer

May 24, 2022 by Denver Express Car Care

Your car’s tires are important for many things. They connect you to the road for a smooth ride. They keep you safe as you move through all the bumps and dips on the road. They control performance and ensure both you and your car remain safe.

Yet because your car’s tires are out in the open, subject to all the perils you meet each day, they are also one of the most susceptible components of your vehicle to potential risks. If a tire goes flat, it can put you at risk. If it isn’t inflated properly, it can decrease the lifespan of your tire.

Your car’s tires are an important part of your vehicle’s overall performance. If you want to keep it safe and ensure a long lifespan, there are a few things you can do.

Tire maintenance – What you can do to make your tires last longer

How much do you know about tire structure and how long they will last? Not all tires are the same. Different makes and models use unique characteristics that will help determine longevity and how well they perform under normal driving conditions.

Many assume tires are made from rubber, but that is only partially true. As many as two hundred different materials are combined to create modern day tires built for comfort, performance, efficiency, flexibility, reliability, and safety.

5 Simple Maintenance Tips For Making Your Car’s Tires Last Longer

Tires are not sold based on how much time they will last. Instead, it’s based on distance traveled. However, if you rarely drive your vehicle, and it sits for extended periods, your tires can still wear down.

You’ll find different types, including all-season, all-terrain, and winter tires. All-seasons have a longer lifespan and will last as many as 70,000 miles. All-terrain are more performance-based, and are rated closer to 40,000 miles. Winter tires are made specifically for the winter season. If you leave them on year-round, you’ll reduce their lifespan. Otherwise you can expect up to six winter seasons of wear.

No matter how well cared for your tires are, they will wear down over time. If you want to make your tires last longer, maintenance is key. Here’s what you can do to ensure they last the entire rated service life.

Check tire pressure

Most modern day vehicles will have an internal tire pressure check built into your computer system. It will alert you through dashboard lights when tire pressure moves beyond the acceptable range. Pay attention to this gauge, as over or underinflation can cause tire damage.

An underinflated tire will allow the sidewalls to flex more than they were designed for as you corner and brake throughout your drive. That leaves the tread not as tight, meaning it won’t stay well connected with the road, creating less stability and traction. You’ll have a slower response both in the way you steer and brake.

An overinflated tire means the center of the tread will bear more of the load. This will ultimately wear the inner tread out faster than the outside edges. It creates less contact with the road, meaning you’ll have more trouble steering and braking.

You can check tire specifications for your vehicle inside your owner’s manual. You can also find it on a label typically attached on the frame inside one of the doors. Be sure to follow these guidelines, as your tires may change as temperatures change quickly here along the Front Range.

Rotate tires

No matter what type of tires you have on your vehicle, each of the four tires will wear separately based on how they connect with the road. This is especially true if you drive a four-wheel-drive or rear-wheel-drive vehicle where two tires will see more wear than the other two.

To counter this process, it’s a good idea to rotate the tires every 6,000 miles or so to ensure even wear. You can schedule this with your regular oil changes; it’s an easy way to remember how often to perform this task.

Maintain proper balance and alignment

Tires can wear differently for many reasons. There can be slight imperfections in tread wear. Tires or wheels may be slightly heavier in some spots.

Over time, this impacts everything about the way you drive. It increases treadwear in certain spots. It can impact fuel economy. It can increase vibration running from your wheels through the steering wheel, making it more difficult to control. This only worsens as you pick up speed.

To ensure your tires stay in balance, be sure to have it checked periodically. You can do so when you get your tires rotated, or when you hit a particularly jarring bump in the road. Most manufacturers recommend having tires balanced and aligned every 12,000 to 15,000 miles.

Monitor your tread wear

Instead of relying solely on a mechanic for tire safety, you can monitor your tread wear yourself to ensure a long lifespan. Plus, it’s easy to do.

Walk around and perform a visual check of all four tires. Look for evidence of uneven wear, cupping, damage, or distortion. If something doesn’t look right, it’s better to check it out. The faster you identify a problem, the quicker you can get it repaired, and the less it will impact the tire’s service life.

You can also perform the penny test. Place a penny into the tread groove upside down, head first into the tire groove. Then inspect the penny. If you can see the top of Abe’s head, it’s time to replace the tires. If Abe’s head is covered, your tires are fine. You can repeat this in multiple places to ensure you don’t have uneven wear.

Adjust your driving style

If you want to keep every part of your vehicle in good condition, while achieving the longest lifespan possible, become a better driver.

Aggressive driving will impact more than just your tires. It affects your braking system, and can impact your fuel economy. It puts you at greater risk for accidents and injury.

It may be fun seeing how fast you can pick up speed, but doing so regularly in urban driving will only increase maintenance items on your vehicle.

Help! My Key Is Stuck In The Ignition

May 18, 2022 by Denver Express Car Care

Driving tends to be an inert activity, repetitive by nature, something you do as a habit every time you slide in behind the wheel.

Then something happens to wake you up to a potential problem. You park, stop the engine, and realize your key is stuck in the ignition.

Now what?

Before you add pressure and risk breaking it off, don’t panic. You can’t walk away with the key in the ignition. That’s a recipe for disaster.

But using brute force will only give you more headaches. You’ll have a much bigger problem on your hands.

Any key should easily slide out of the ignition once you have rotated it to its original position. If it doesn’t come out, there are several possible reasons.

Why a key gets stuck in the ignition

There are many reasons why a key can get stuck in the ignition.

Your car isn’t in park

If your car’s parking gear isn’t properly set, you might not be able to remove the key. Double check to ensure you’ve moved the gear shift to the “park” position. If you have an automatic transmission, the vehicle must be in “park” before the key can be removed. You can play with the gear shift moving it out of park and back in to see if you can fix the problem. With a manual transmission, you can move the shift to neutral and see if the key has any give. Playing with the shift function can sometimes cause the key to give.

The steering wheel is locked

If you move the steering wheel while turning off your vehicle, sometimes it can activate the steering wheel lock before the key releases. Not only will this prevent you from turning your steering wheel, but you won’t be able to pull the key out of the ignition. The ignition cylinder lock is activated at the same time as the steering wheel lock. To release both locks, simply turn the key gently while moving the steering wheel around. You should hit a point when both locks open up.

There’s debris on the key

Think of everything you put your key through. It’s shuffled around from pockets and handbags. It’s thrown in with a variety of other items. You use it to open boxes and packages. Over time, tiny particles can reside on the key until they change the structure of the key enough to impact functionality. You may notice it gets increasingly difficult to remove over time. Cleaning your key from time to time will ensure it keeps working at its best.

Your key is damaged

After years of abuse, a key can simply stop working. It may have tiny cracks, or the grooves have worn away. If you notice any damage, replace the key immediately. It’s a good idea to always have a spare for this reason. It provides you with an original key structure to fall back on.

Your battery is dead

The ignition system requires power from your car’s battery to function. If the battery dies, it will most likely cause the ignition system to lock up. If that happens when you’re trying to remove it from the ignition, it will get stuck. The best thing to do in this situation is to jumpstart your vehicle and see if it releases your key.

The ignition cylinder is bad

A vehicle is made from 10,000 parts. At any time, any one of those parts can go bad. If the ignition cylinder fails, it can lock in your key and prevent it from releasing. This is because there are rows of spring-loaded pins that align when you place the key into the ignition cylinder. Once in place, they hold on tight. Failure at this point will require repair work on the ignition system to fix the problem.

How to get a stuck key out of the ignition

What it takes to get your key out of the ignition depends on the situation. If you are armed with the above knowledge, you’ll have a few things to try.

But you should also pay attention to the process. Is this the first time you’ve had trouble with your key? Has it been getting worse over time? That can also weigh in as to what might be wrong.

If this is the first time you’ve had trouble, the most common reason is a gear that isn’t quite in the right place. Confirm your gear shift is in “P” or “park.” You can move it out and back in to ensure the gears are properly aligned.

Then jiggle the steering wheel. It’s also common for the steering wheel column lock to move into place, locking up the ignition too. Don’t put too much pressure on either, just a gentle wiggle will sometimes release the lock and key.

If this is a growing or common occurrence, you might have bigger problems.

Start by cleaning off your key. Use rubbing alcohol to get into the cracks. If you notice adhesive or a more stubborn substance, an adhesive remover might do the job.

If you still haven’t solved the problem, your next step should be bringing your car to a mechanic to fully assess what’s happening with your vehicle. A mechanic can determine if it’s time to replace the ignition lock cylinder.

And if the worst has happened, and the key has broken off in the ignition, you’re not the first person who has had to deal with this problem. It can happen when you apply too much force trying to remove it.

Do not try and insert the top half of the key to try and get the bottom half out. If you do anything to try and pry out the bottom half, you may push the broken half further into the lock, making it even more difficult to repair. Locksmiths do use key extractor tools to remove broken pieces of keys. Be sure to call in a professional, so you don’t further damage other parts of your car.

Have you ever experienced a key getting stuck in the ignition?

What Cold and Heat Does To Tires

April 7, 2022 by Denver Express Car Care

Living in Colorado can give you a wide array of environmental challenges, sometimes all in the same day. Statistics show temperatures have climbed as high as 115 degrees Fahrenheit and dipped as low as -61. We’ve had more than 75 inches of snow in a 24-hour period, and have had hailstones as large as 4.83 inches in diameter.

Stick around, and you’ll see it all.

But those kinds of variances can be hard on your tires. What do cold and heat do to tires? Should you be more careful in certain driving conditions? What puts your tires at risk?

Why tires are susceptible to changes in weather conditions

What are tires made of? Most people would say: rubber. That’s only partially correct.

Rubber is one of the main materials used in tire production, but there are as many as 200 different components combined to create new tires. Steel, nylon, silica, polyester, carbon, petroleum, as well as natural and synthetic rubber are all used to make tires stronger, better. It’s complex engineering to make tires do what they do best.

The outside tread creates traction and mileage. Inside the tire provides stability and strength. Together it helps your vehicle perform well out on the open road, as well as keep you safe no matter where you drive.

Tires are often created with certain performance requirements in mind. That’s why you’ll find a variety of types: snow, all-season, performance, and traction.

Depending on what tires are mounted to your vehicle will determine how susceptible they are to the driving conditions. Cold weather decreases tire pressure while hot weather increases.

As temperatures outside rise, the air in your tires increases in volume. As temperatures fall, the air volume in the tires decreases. That’s why your car’s computer module may indicate your tires are low in pressure after a plunge in temperatures outside. In general, tire pressure usually drops 1 to 2 psi for every 10 degrees the temperature drops. That’s also why air pressure will rise as your tires warm up as you drive.

Every tire manufacturer produces tires with a recommended psi. This psi tells you the optimal pressure for your tires and your car. However, this psi is set for cool tires. If you check your tire inflation at the filling station after your tires have warmed, it will be a different reading from when they were cool. It’s best to check your tires at home, if possible, before your tires have a chance to warm up.

Summer driving

As the temperatures continue to climb in summertime, your tires increase in volume and may overinflate. Most technology systems are wired to tell you when your tires are underinflated, but not when they are overinflated. This is why it’s important to test your tires manually periodically, especially with record-breaking heat or if you’re driving more than usual.

This can be especially true if you take long trips, or are carrying heavy loads. This is why tires blow on occasion.

Coupled with improper inflation is weakened tread. Tire tread is measured in 1/32 of an inch. If you have uneven wear patterns in the tread of more than 2/32 of an inch, it’s time to replace your tires. You can also do the penny test. Place a penny in a shallow groove on a tire with Lincoln’s head facing down. Can you see the top of his head? That means the tire tread is too shallow, and your tires are considered worn. The tire tread is 2/32 of an inch or less, and it’s time to replace your tires.

Winter driving

In winter, the opposite is true. Your tires may become underinflated in cold weather, and the tire pressure may drop accordingly. Unlike in summer months, air pressure readings will be accurate. Your vehicle’s computer system will be more likely to pick up on proper inflation of your tires.

That doesn’t mean you shouldn’t still check it manually on your own from time to time. Don’t forget your spare.

You should also pay attention to driving conditions, and perform a manual check if problems arise. Snow and ice wreak havoc on our roads. Potholes, hitting curbs, icy terrain – it can all wear your tires down. Be conscious of any potential problems that may impact your tires, and have them checked before you continue driving.

Heat and cold impact tires. Don’t drive if you suspect a problem.

Tires are designed for a multitude of purposes:

They support and cushion the weight of a vehicle
They absorb the shocks occurring as you drive on a road
They provide traction in different driving conditions
They add torque and braking force as they connect to the pavement
They allow you to easily keep control of the vehicle as you change and move the direction in which you travel

Without high-quality tires, you’ll be putting you and those around you at risk.

You should never drive on bad tires. It’s something you should check on a regular basis to ensure they are in good shape.

However, your tires wear and performance can change quickly in different situations.

If tires lack tread, you can pick up on it with visual checks. But if they are over or underinflated, it may be more difficult to notice as you drive.

Awareness is key in keeping your vehicle safe and under control.

If tires are weakened or lack tread, they are more vulnerable to the dangers of the road. Punctures and blowouts can happen more frequently, putting you and your passengers at risk.

Don’t wait to change your tires, replace them if damaged, or even have them checked if you suspect a problem. The sooner you react, the better your chance of fixing the problem, and possibly adding more life to your tires. Proper inflation can add many more miles of life to your tires.

How To Make Your Car More Efficient With Gas Prices Rising

March 24, 2022 by Denver Express Car Care

Remember when gas was under two dollars a gallon? Prices plummeted two years ago as the world came to a halt. And ever since, they’ve been rising steadily upward. Will they hit four dollars? Five? Only time will tell.

You feel it every time you pull into a gas station. Depending on the car you drive, you may have even reached a pump limit of $100. Now what? How do you make your car more efficient with gas prices continually rising? Or will you have to cut back in other areas of your life to meet this new reality?

Understanding fuel efficiency

Want a gallon of gas today? The national average is just over $4.24 a gallon. Compare that to $2.88 just a year ago, and you can easily see where your hard-earned money is going, especially if you’re back to driving to work every day.

It might lead you to wish for a more fuel efficient vehicle. What is fuel efficiency anyway?

Fuel efficiency measures effort to convert energy from the fuel into kinetic energy your car needs to move. It’s the measure of how far a vehicle can travel on one gallon of gas.

How To Make Your Car More Efficient With Gas Prices Rising

A lot of variables control how fuel efficient a car will be: tires, design of the car, weather conditions, driving conditions, just to name a few. While you may hear the terms fuel economy and fuel efficiency used interchangeably, they aren’t the same thing. Fuel efficiency is broader and includes how a vehicle uses the fuel. And that’s where you have some control.

While your car may have come with fuel efficiency guidelines, there are things you can do to save on gas. Fine-tuning your driving strategies can help you save at the pump, and make your car last longer too.

Car efficiency tips

Want to know how to make your car more efficient? It might be easier than you think. We have a few tips for you that don’t cost a lot and take little time to implement. Being aware of what impacts fuel efficiency is often enough to help you drive differently, depending on the conditions.

Clean out your car

Today’s vehicles are bigger than ever. We also weigh them down with many different things. Walk around your car and take a look at the extras. Do you have ski racks and cargo bins on top? Do you have bike racks tacked to the back? Do you carry workout items, sports equipment, and extra tools in the back? All of that adds unnecessary weight to your vehicle. Studies show you can lose 8 to 10 mpg with these extras in place. And at today’s gas prices, that can really add up. If you’re not using the extras, consider taking them off for your daily commute. You can always add them back when heading away for the weekend.

Improve your driving

Take a good look at the way you drive. Are you offensive or defensive in your daily driving patterns? Do you drive aggressively in traffic? Hard acceleration and braking can decrease your fuel efficiency by several miles per gallon. Instead, practice smooth driving. Leave space between you and the car in front of you. Leave early, so you have a few minutes to spare. Anticipate what’s coming up so you can smoothly transition as you drive. Not only will this help with fuel economy, but it will also help make your drive safer in the process.

Don’t speed

While there’s evidence that higher speed limits increase the risk of accidents, there’s also sufficient evidence that higher speeds also consume more gasoline. As you reach 45-50 mph, your car starts to lose efficiency. The faster you go, the more the numbers drop. Driving fast may get you there in a shorter period of time. But when fuel efficiency matters and you’re trying to conserve how much you pay at the pump, slowing down will help you conserve.

Check your tire pressure

When your tires are underinflated, it lowers your fuel economy. It also puts you at risk. Tire pressure controls how well connected your vehicle is to the road. If they aren’t inflated properly, they can’t do their job efficiently. While many of today’s vehicles have sensors telling you of a pending problem, it’s worth checking your tire pressure regularly to ensure they are properly inflated.

Buy quality gas

One of the easiest ways to make your car more efficient is to pay attention to where you purchase your gasoline. Top-tier gas stations are held to higher standards with additives. By filling up at a reputable station, you are ensured you’re getting good quality gas that will keep your engine working well. Also pay attention to what type of gasoline your vehicle needs to drive well. Stick with premium if the manufacturer suggests it, as it keeps your car running well. We also recommend keeping your tank at least half. This reduces the risk of running out, and protects you in case of inclement weather or gas shortages.

Perform regular maintenance

A well maintained vehicle will always perform better than one with potential problems. Dirty air filters, faulty spark plugs, or outdated oil changes all impact performance. Sticking with a regular maintenance schedule ensures your vehicle performs at its best ability, and helps catch potential problems before they escalate. That keeps you safer while driving on the road, and can save on repair bills over time.

How can you make your car more efficient now that gas prices are rising once again? It doesn’t take much. Just a few proactive tips can make a difference each time you pull in to fill up.

Does Changing a Cabin Air Filter Really Make a Difference?

February 24, 2022 by Denver Express Car Care

Cars provide an invaluable service. They:

Get us from point A to point B each day
Shelter us from the heat and cold
Allow us to travel long distances comfortably
Give us easy ways to transport things we need
Keep us safe from harm

For all those reasons and more, it’s important to keep your vehicle in good working condition.

When was the last time you thought about checking your vehicle’s filters?

While the oil filter may have been changed the last time you stopped in for an oil change, when was the last time you checked your cabin air filter?

What’s a cabin air filter?

When it comes to filters, your car has several to keep it operating well. They include:

Air filter – prevents harmful debris, dirt, and contaminants from entering your engine
Oil filter – removes contaminants from your car’s motor oil
Cabin air filter – prevents dust, pollen, dirt, and other pollutants from entering your vehicle through the cooling and heating vents

The cabin air filter is the one most vehicle owners miss because they often don’t know it exists. A cabin air filter is specifically designed to help filter the air supply inside your vehicle, creating a cleaner environment while you ride in your car. As you exhale, it takes in the air supply and moves it through the filter. As air comes in from the outside, it filters out pollen and dust to prevent further aggravation for allergy and hayfever sufferers.

Like other filters, over time, cabin air filters can become dirty and clogged with harmful contaminants and debris. They no longer serve their purpose if they can’t filter air through the filter, and instead let the pollutants and contaminants back into the air supply.

Does Changing a Cabin Air Filter Really Make a Difference?

If you notice a bad smell coming from the vents as you use heat or air conditioning, there’s a good chance it’s time to replace your cabin air filter.

When should I replace a cabin air filter?

While a cabin air filter might not need replacing as frequently as an oil filter, it’s still a good idea to keep it on a schedule and change it often.

Take a look at your owner’s manual. It will give you an idea of manufacturer’s guidelines, and when your car’s designer suggests you change out the cabin air filter. Typically you’ll find that manufacturers recommend replacing it every 15,000 to 30,000 miles or so.

Timing may be your starting point, but you should also factor in how you drive. Those who drive in urban, congested areas regularly will need to replace the filters more often. If you live in a rural location and dirt roads are a part of your daily drive, the filter may clog with dust and debris faster than by taking paved roads.

Will a dirty cabin air filter show signs of wear?

Like other parts of your vehicle, the cabin air filter doesn’t wear down in an instant. Instead, it will start to provide you with indicators that its clogging and no longer doing it’s job. You may notice:

Reduced air flow – when you crank the heat or air conditioning up too high and it still doesn’t seem to get the job done, it may be an indicator of a clogged cabin air filter.
A whistling sound – the higher speed you use for controlling the air supply, the higher the whistling sound coming from the cabin air intake ducts.
A distinct musty odor – you can’t ignore the foul smell that comes every time you turn your vents on. It may even worsen over time if you continue to ignore the problem.
Louder noises while the heating or cooling system is running – your heater and air conditioner have to work harder to meet the demands of the system. It’s trying – and you’ll hear it working. The noise will increase until the entire system is well maintained.
Fog on the insides of your windows – if the cabin air filter is allowing pollutants and contaminants to blow out into the air supply, some of the debris may land on your windows and create a fog. This isn’t moisture, it’s actually particles landing on your window, and preventing you from seeing clearly.

What can you expect from a new, clean cabin air filter?

The good news is that replacing an old cabin air filter with a new one, it will help your car run better. A well maintained vehicle won’t leave you stranded when you least expect it. It will also give you many more years of service, and be a reliable addition to your lifestyle.

Changing out your cabin air filter will give you:

Better performance – air filtration is a crucial part of overall vehicle maintenance. Your car needs two things to operate efficiently – air and fuel. A clean air supply makes every aspect of your vehicle’s operational systems more effective.
Better air supply – how much time do you spend inside your vehicle? According to the EPA, people spend 90 percent of their time indoors, where concentrations of some pollutants have been shown to be as much as five times greater than outdoors. Imagine how many contaminants you’re breathing in if you spend an hour or two each day tucked away inside your vehicle?
Better reliability – how often do you use your heater or air conditioner? Trick question, because you might always have one or the other on, keeping your vehicle at your desired temperature. Every time you operate the heating and cooling system, it depends on the motor for energy. If it isn’t efficient, it requires more power from the engine. That puts undue stress on your engine, meaning it might need repair or even replacement sooner rather than later.

Is it time to replace your cabin air filter?

If you can’t remember the last time you replaced your cabin air filter, now may be the perfect time. Be prepared for springtime pollen season by giving your ventilation system a little TLC.

Changing out the cabin air filter will improve air quality and prevent allergy problems by filtering out pollen and mold spores, dirt, and other pollutants.

It’s one of the easiest ways to ensure your vehicle remains well maintained.

This Is How You Tell If Your Brake Calipers Need Replacement or Repair

January 10, 2022 by Denver Express Car Care

The braking system is one of the most important systems on your vehicle. While you might be familiar with brake pads and brake fluid, brake calipers are a little more obscure. What are they? What do they do? And how do you maintain them throughout the life of your car?

What are brake calipers?

Owning a car means performing regular maintenance. For your braking system, the most often parts to be replaced include the brake pads.

Manufacturers recommend replacing brake pads every 10,000 to 20,000 miles. When it comes to the brake rotors, you have a bit longer. Rotors should be replaced every 60,000 to 70,000 miles to ensure your braking system remains in great shape. While not as common as motor oil, your brake fluid should still be replaced every four to five years. If you haven’t read through your owner’s manual, it’s a good thing to keep on hand.

Brake calipers also need replacing over time. Through wear and tear, they lose their ability to clamp down and relax the brake pads as you apply and release pressure.

A brake caliper is a part of the disc brake system, which is what most vehicles have on their front brakes. You can see it sitting on your wheel if you look through the spokes. The brake caliper houses the brake pads and pistons. Its sole job is to slow the car’s wheels as you press down on the brake pedal, to create friction against the brake rotors.

Inside the caliper, a powerful piston uses pressure from hydraulic fluid to press the brake pads against the brake rotor. When working properly, the calipers move effortlessly based on the amount of pressure from the brake pedal.

This Is How You Tell If Your Brake Calipers Need Replacement or Repair

When something in the system breaks, wears down, or stops altogether, that’s when you have a problem.

Brake caliper alerts – how to know when you have a problem

Like other systems on your vehicle, the braking system has all kinds of warning signals to alert you when things aren’t working correctly.

Most vehicles have sensors to art you to braking problems. The brake light on your dashboard will illuminate when the sensors detect something is wrong within the system.

The brake light could trigger if you’re low on brake fluid, or the pressure isn’t within set guidelines. It can also alert you to brake pads wearing down if the car is equipped with pad sensors. The dashboard light is designed to give you plenty of time to set up a service visit and fix the problem before it escalates.

Unfortunately, problems with the brake calipers can be a little more challenging to detect.

Where’s the brake caliper problem?

There are several ways you can identify and prevent further brake caliper breakdown.

Noises, smells, and feelings

Driving is often one of those mindless tasks you perform on autopilot. But it is a good idea to stay alert and pay attention to what your car is trying to tell you. The first problem with any system is often identified through one of your senses.

Does your car drive differently? A malfunctioning caliper can cause your vehicle to pull to one side as you drive. This is due to an unbalanced braking system. Because one caliper doesn’t provide pressure in the same manner as the other side, you’ll notice your car lurching forward, or pulling to one side as you slow and stop.

You may also hear a squealing or grinding sound. This happens when brake pads run thin, and can’t connect with the rotors efficiently. Is it the brake pad, or is it a caliper malfunctioning that caused it to wear down before its time? If you’re nearing the lifespan of your brake pads, it may be the problem. But if you still have life left on them, it may be worth further investigation.

Too much pressure on the braking system can also ramp up the heat within the system. If you notice a burning chemical smell near one of the front wheels, it may be a sign of overheating from the brake pads and the bonding agent.

Do a visual inspection

If you’ve ever boarded a plane early, and watched outside the window, chances are you’ve seen the pilot walk around doing a visual inspection. Why? He’s in charge of the plane, keeping the passengers safe, and the plane in good working condition. It’s up to him to decide if it’s okay to fly, and if he’s comfortable with the mechanics and technology he’s been given.

Driving works similarly, though most of us rarely take a walk around our vehicles before jumping in behind the wheel each time we drive. But there is something to learn from a pilot – it’s a good idea to do a visual check from time to time. Do you notice tire tread wearing unevenly? Is there liquid accumulating near the caliper or the wheel? Keep an eye on anything that looks suspicious, and bring it in for inspection at your earliest convenience.

Proper maintenance means prevention

Luckily, it won’t take much time out of your day to ensure your vehicle is working well. With an occasional visual inspection, and a moment or two paying attention to what your car is trying to tell you, you’ll be able to drive securely with the knowledge that everything is working well.

Bring in your car for regular motor oil changes. Ensure your tires are properly inflated, and your wheels are properly balanced.

Let a mechanic run through a checklist to ensure everything is working well. You can schedule this at the start of each season. Or if you’re heading out on the open road. It’s a great way to keep your security in check to ensure something bigger doesn’t happen.

Braking problems? It might be caliper issues

Your brake calipers are designed to last 100,000 miles or more. They aren’t a component that needs to be replaced often.

Being aware of potential signs of a problem will ensure your braking system continues to work well. It’s the best way to keep your passengers safe, and your vehicle operating well.

When was the last time you had your braking system inspected?
