6 Signs of a Bad Fuel Pump

June 28, 2022 by Denver Express Car Care

Today’s modern fuel pump is designed for effectiveness and efficiency.

An electrical fuel pump is used by all modern day vehicles that still rely on gasoline for power and energy. It works by utilizing a motor in the fuel pump assembly to draw in fuel you’ve previously pumped into the fuel tank. From there, fuel travels up into the fuel line, and into a fuel rail where it’s injected into the cylinder. It mixes with air and a spark to create combustion.

The pump contains a filter at one end to keep any impurities from moving past the fuel tank and into the fuel line. There’s also a fuel float that sits on top of the fuel supply and sends out a signal to the sensory board. It reads the resistance and relays the message to the fuel gauge, telling you how much fuel is left in the tank.

It’s a simple process, and when it works correctly, your entire system is an effective machine.

Yet because it’s part of a bigger picture, one piece among many in a vehicle with over 10,000 parts, one small failure can impact the entire system. And it’s often difficult to tell which component is failing.

Types of fuel pumps

Older vehicles relied on a mechanical fuel pump to achieve results. The mechanical pump would draw fuel in, trap it, then move the fuel toward the carburetor and engine. It was a cyclical movement, repeating the process repeatedly.

Electric fuel pumps use an injection process with high powered pressure. It’s accomplished by using an electrical process rather than mechanical. They come in several formats:

In-tank – the majority of fuel pumps reside inside the fuel tank. This helps protect the module, keeping it cool as it operates.
Inline – these are easier to replace as they are mounted outside of the fuel tank, somewhere between the gas tank and the engine.

While there are others, these two make up the majority in cars today.

How long a fuel pump lasts

While fuel pumps aren’t a part of a regularly scheduled maintenance routine, like any part on your vehicle, they won’t last forever.

Most manufacturers today will state that a fuel pump should last well past 100,000 miles. They aren’t part of a preventative maintenance package that should be replaced “just because.”

Yet they can and will fail the longer you drive your vehicle. Luckily, they start to give warning signs before they shut down completely.

That’s where paying attention to your vehicle can pay off. If you notice any of these warning signs, bring your car in for a full inspection. That gives you a chance to make the repair before it leaves you stranded, or causes even more damage down the road.

Engine faltering at high speed

As you pull onto the highway and drive consistently at higher speeds, you may notice your vehicle falters a bit before returning to its regular performance. This is a classic sign there may be something wrong with the fuel pump. This sputtering occurs as the pump struggles to keep a consistent stream of fuel moving into the engine for proper pressure. This causes a hit or miss chain as the fuel circulates, causing the engine to falter as it reacts.

Vehicle dies with a heavy load

Are you pulling a trailer, or simply have your car loaded down with materials? The extra weight could add pressure to an already faltering fuel pump, cutting off the fuel supply and making it sputter. When the fuel pump can’t supply the correct fuel supply to keep your vehicle operating, especially under more strenuous circumstances, it’s a sign something might be wrong with the fuel pump.

Low fuel pressure

Low fuel pressure can show up in many ways. Is your car misfiring frequently when you start it up for the day? Does it feel like the acceleration is compromised? Do you experience a rough idle when you leave your car sitting and running? Does the engine stall at different points of your drive? You should also pay attention to any dashboard lights that may illuminate any time your car is in operation. The Check Engine light can signify many different problems with the vehicle. The best way to find what it is will be to bring it in for a full diagnostics test, to get to the root of the problem.

Slow acceleration

If the fuel pump isn’t doing its job, it can’t effectively regulate the fuel supply. That means the system might be pulling too much gasoline at certain points, while not enough gasoline at other times. That can cause acceleration to be compromised. If you aren’t getting the necessary supply of fuel, your car won’t perform.

Loss of gas mileage

Tracking your gas mileage is an easy way to determine problems with the handling of your vehicle. By tracking numbers with every fill up, you develop a pattern for how your car operates. You’ll know if mileage suddenly decreases, you have a potential problem. Fuel pumps have a release valve that allows more fuel to flow into the engine if it fails to open. You’ll notice this by having to fill up more frequently. And at today’s gas prices, that can be a massive uptick in your budget.

Engine fail

If you face any of the above conditions regularly and continue to ignore them, eventually, your engine is going to refuse to start. If fuel doesn’t flow into the engine during the starting process, or flows unevenly throughout your entire driving experience, it’s going to impact all of the pieces in the system. That much stress on the fuel supply will cause the car to no longer start.

All signs point to a bad fuel pump?

Don’t ignore it. It won’t go away.

Instead, schedule a visit with one of our mechanics. We’ll inspect it, diagnose the problem, fix it, and have you back on the road in no time.

It Might Be a Clogged Fuel Filter

June 24, 2022 by Denver Express Car Care

Your car’s fuel filter isn’t a component you deal with regularly. In fact, it’s easy to ignore.

It’s hidden within your vehicle’s fuel supply system. It’s one of the easiest to overlook, yet also one of the least expensive parts you can maintain.

Most modern day vehicles have two fuel filters. The first is located in the fuel tank, often referred to as a strainer. The other is in the fuel line.

These fuel filters are made from plastic, metal, or coated pleated paper. Fuel filters are designed to trap dirt, debris, rust, and other impurities from the fuel supply, straining it out before moving to the rest of the fuel system. It protects the engine and fuel injectors from harmful particles.

These fuel filters are built with incredibly tight materials to block impurities from moving into the fuel supply. This is critical because modern engines are fine-tuned and can be damaged by even minor intolerances. Any foreign particles that do make their way past the fuel filter have the potential to cause blockages and damage to the engine.

The cost of the fuel filter is minimal compared with the potential damage it can cause.

How do I know if my fuel filter is clogged?

Like other parts and systems on your vehicle, a clogged fuel filter will give our warning signs when it’s compromised. This is where paying attention can help save time and money on potential repairs.

Poor engine performance – poor engine performance is especially noticeable when you push your vehicle while accelerating, or when you add more weight to your load. Do you notice hesitations, surges, or sputtering? This is often caused by fuel restriction. If the fuel supply can’t get through the fuel filter as designed, it will impact every aspect of the way your engine performs.

Trouble starting the car – a clogged fuel filter rarely makes it to the point where it causes problems when starting the car, but if you leave it unchecked, it could be part of the problem. A clogged fuel filter causes erratic flow of gasoline, which results in poor engine performance.

Misfire or rough idle – when driving on a clogged fuel filter, it can lower fuel pressure enough to cause the engine to misfire. You may also notice this in poor gas mileage. If you leave your car idling, it may feel a bit rough, or even cause the check engine light to pop on. If it gets to the point of triggering the sensor, it’s time for a visit to the local repair shop.

Stalling – if your car repeatedly stalls out while you’re moving throughout the day, it’s a sign of a clogged fuel filter. As a clog worsens, it impacts the delivery system of fuel. When fuel can’t make it through the system as desired, it impacts the way your car handles.

How long will fuel filters last?

In general, manufacturers recommend changing out a fuel filter about every 30,000 miles. Of course, it depends on your vehicle. Check your owner’s manual for more details.

This is where maintaining a log can help you with early maintenance. As you get closer to the 30,000 mark, you can start watching for potential problems. Or simply bring your vehicle in for inspection and replace the fuel filter at the first sign of a problem. Being proactive will always benefit you, and prevent problems while driving down the road.

Can you clean a fuel filter?

Many different appliances you use in your daily life have filters that can be cleaned instead of replaced. With a fuel filter, they are made from a thin plastic or paper material that is easily compromised as it’s used. While you will find search results online that direct you how to clean it. For optimal results, it’s better to replace it.

Some fuel filters have metal elements that will direct you in ways to clean it. But the majority of fuel filters are designed to be used once and then replaced.

Changing a fuel filter will impact fuel efficiency

Today’s gas prices are climbing higher and higher. If you’re tired of watching your gas payment take a bigger bite out of your budget, fuel efficiency may be something to think about.

A clogged fuel figure equates to poor fuel efficiency.

A clogged fuel filter allows impurities to flow from the gasoline you pump at the station to all of the various components in the engine compartment. Clogged fuel filters eventually cause engine damage, prevent smooth drivability, and decrease fuel efficiency.

When trying to make the most of every dollar you put into the tank, servicing your fuel filter first will keep the costs down overall.

While manufacturers suggest replacing it every 30,000 miles, you can make it a part of your regular maintenance schedule, replacing it every other year.

Pay attention to how you drive. The more strenuous your drive is on the engine, the more maintenance visits you should schedule. If you do a lot of hauling, drive gravel or dirt roads frequently, or push your vehicle more in your daily commute, staying proactive will ensure the fuel filter stays cleaner and your engine stays healthier.

What fuel filter is best for your vehicle?

Not every vehicle uses the same type of fuel filter. Using your manufacturer’s information will point you in the right direction.

Fuel filters include:

Primary fuel filter – used commonly in diesel fuel systems
Canister fuel filter – shaped like a canister with a filtration system inside
Cartridge fuel filter – they include a cartridge containing the filtration media, structural components, and the fuel filtering parts
Spin-on fuel filter – uses threads to attach to the engine compartment
Inline fuel filter – mounted on the fuel line between the gas tank and the engine
In-tank fuel filter – mounted inside the gas tank

That’s why most vehicle owners leave it to the experts.

If you’re having problems with your vehicle’s performance and you suspect it may be a clogged fuel filter, your best course of action is to schedule a maintenance visit.

We can assess the situation, find the problem, and help get you back on the road as quickly as possible.

This Is Why Your Transmission Is Slipping

June 18, 2022 by Denver Express Car Care

Your transmission is slipping. Even if you have no idea what that means, it just sounds bad, doesn’t it?

In the simplest terms, a car transmission is a gearbox. If you think of the gears and chain on your bicycle, that’s a good place to start.

The parts of a transmission are connected to the engine so that the gear and belt system effectively respond to the power produced by the engine, providing the transmission with momentum.

When you turn the key to start the car, fuel ignites in the combustion chamber. As it ignites, gas and heat expand and push pistons inside the engine’s cylinders. As they move up and down, they spin the engine’s crankshaft. This in turn connects and moves the wheels.

Most transmissions have five or six sets of gears and gear trains (belts or chains) that help a driver operate the vehicle at different speeds. As power moves based on how much gas you give it, the gears move accordingly. Without the transmission, the entire start and stop movement wouldn’t be possible.

How a transmission works

Cars will have a manual or automatic transmission. The only difference between the two is how much participation a driver has in the process. With a manual transmission, the driver pushes a clutch to engage the clutch plates and gear levels, then moves into the desired gear. An automatic transmission has an automatic clutch that performs each movement based on how fast you’re driving.

A gear lever selects and moves gears to connect with the appropriate gear. When engaged, this gear level moves a clutch plate into position to connect with larger gears. This process continues to change and shift gears based on your speed and actions, delivering power from the engine to each of the wheels.

This Is Why Your Transmission Is Slipping

Each gear is shaped with teeth to fully engage as they move. If you hear the engine making a horrible grinding sound, it may be because the clutch plate doesn’t align properly with the gear teeth. While it might be easier to hear if you’re driving a manual transmission, you still can’t ignore the grinding sound as it tries to engage while moving into a higher gear.

What does it mean when your transmission is slipping?

When a transmission is slipping, it can feel like the vehicle is slow in response time. When you press down on the accelerator, nothing happens. It may or may not be accompanied by a noise, such as a clunk, similar to what happens when it changes gears. You may also notice it while driving at a consistent speed, it suddenly slips into a different gear. This can be caused by several things:

Fluid – a transmission operates with transmission fluid to keep the gears well lubricated. If the levels are too low, or there is grime and dirt in the transmission fluid, it might prevent the gears from moving as they should.
Gears – gears work together with teeth grips, connecting with each other as they go around. If those teeth are worn down or contaminated, they may not fully connect and grip.
Transmission bands – these internal bands are used to engage and disengage the gears. Over time, these can wear down and become less effective.
Solenoid – this controls fluid distribution. If the proper levels of fluid aren’t circulating, it impacts every part of the system.
Torque converter – this is the connector piece between the transmission and engine. If it fails or doesn’t operate correctly, the transmission will not operate as designed.

Most transmission slippage problems are from low or worn out transmission fluid

It’s the number one reason vehicles experience transmission slippage. Luckily, it’s also an easy problem to fix.

Most manufacturers suggest replacing transmission fluid every 30,000 to 60,000 miles. Considering transmissions need full replacement around 100,000, that equates to two or three changes before it’s time for a new transmission. Depending on how much you drive each year, that could signal new transmission fluid should be checked and changed every two to three years.

Depending on how your transmission is designed determines how easy the process is. Many systems are completely closed and require professional servicing. Transmission fluid is typically translucent and dark red when new, but will grow even darker as contaminants are introduced.

Like motor oil, transmission fluid can be checked with a dipstick. Pull it out from the filler tube and look at the color. Transparent red means it’s like new. Dark brown signifies it’s time for a fluid and filter change. If it appears light pink, it signifies water or coolant has made it into the system. It’s time for a rebuild or repair.

Can you drive with a slipping transmission?

When trying to decide whether to continue to drive, think about all the things that might be wrong.

If it’s leaking transmission fluid, what’s happening internally without proper fluid levels?

If it’s making a funny noise, how are all the parts interacting?

If you feel the car not engaging at different speeds, does it put you at risk while out on the road?

Can you drive with a slipping transmission? Technically, the answer is yes.

Yet driving with a bad transmission will definitely put you and your vehicle at risk.

Continue to drive, and the damage may escalate. What might have been stopped with a minor repair can quickly escalate.

And if gears slip and won’t engage to help you keep your vehicle under control, it can put you at greater risk for an accident.

If you’re unsure of how bad your transmission problem is, inspecting it will pinpoint the issue and get you back on the road safely once again.

Stop by today and let us inspect your vehicle. We’re here to run diagnostics and fully check your issue to get to the heart of the problem. We’ll help you determine what’s wrong with your vehicle, find a solution, and keep your car operating as efficiently as possible.

Is your car experiencing transmission slippage?

Sedans and Trucks Need a Different Level of Maintenance

June 14, 2022 by Denver Express Car Care

Reliability. That’s a word drivers regularly use when they start shopping for a new vehicle.

Whether you’re in the market for a sedan or truck, maintenance should be a simple process, with the potential for major issues to be kept at a minimum. Which is better?

Truck drivers will argue you can get more longevity from a truck. Drivers that prefer family cars focus their attention on four-door vehicles. Is one more reliable than the other?

What is reliability?

Reliability is defined as: the quality of being trustworthy or performing consistently well.

If you look at Consumer Reports, they attain reliability demographics by surveying members each year. In 2021, they received data on over 300,000 vehicles from 2000 and 2021 models. They track any problems with the vehicle that resulted in a repair bill, including warranty work.

If you ask drivers what they want from a reliable vehicle, they most likely want:

A car that doesn’t break down.
A vehicle where every repair is an expensive transaction that’s difficult to budget for.
A car that’s difficult to troubleshoot – every issue requires digging deep to find the root cause.

Reliability is most likely tied to the biggest components of a vehicle:

The engine
The transmission
The braking system
The electronic system (computer)

Adding motor oil to a vehicle is an inexpensive, routine maintenance item we expect. A blown transmission or a failing brake system could cost thousands of dollars, depending on what the problem is.

Sedans and Trucks Need a Different Level of Maintenance

What’s more reliable, sedans or trucks?

Every driver would have their own opinion on this, but a site called iSeeCars analyzed over 14.9 million cars sold in 2021 to determine the most reliable vehicle on the road, with the highest percentage reaching over 200,000 miles. Their findings included nine SUVs, three pickup trucks, two minivans, one sedan, and one hybrid hatchback rounding out the top fifteen.

Keep in mind that these vehicles were pushed for testing purposes. According to Kelley Blue Book, the average person puts on 14,263 miles per year. It would take you over 14 years to reach the 200,000 mark.

What should you consider?

Trucks and sedans are built differently. Therefore their required general maintenance will be on a different schedule as well.

Whether you own a truck or a sedan, preventative care and maintenance are key for extending lifespan. If you want a long-lasting car, being regular with fluid checks and inspection visits will ensure you get a full life from your vehicle.

Frequency of maintenance – Every model will have its own guidelines for inspecting and replacing different parts on a car. For oil changes, most manufacturers recommend a sedan be serviced every 3,000 to 5,000 miles, while a truck can wait up to 7,500 miles. Tires for a truck or built for hauling and pulling more weight. Tires for a sedan are built for performance, and tend to wear out more quickly. If you’re debating between two specific vehicles, you can compare guidelines posted by each manufacturer to help you finalize your decision.

Parts – if you’re planning on owning your vehicle for years, you can consider how easily you’ll be able to replace parts as they wear down, and how expensive they will be. After-market parts give you a chance to replace worn out parts with a comparable product that is more competitive and cost-effective. Trucks are designed to accept after-market products easily, so there’s almost always a way to fit a repair into your budget. Depending on the sedan you select, that might not always be the case. Specialty cars like BMW and Audi often require specific services to keep the sedan updated. That can make upgrading or replacing parts more expensive.

Drivability – when you look at the suspension system of the two, a pickup truck offers higher ground clearance. They also have an increased suspension system to lessen the effects of the road. That’s why pickup trucks are more comfortable and safer for off-roading. Sedans are meant for comfort. They sit lower to the road and have built-in suspension parts to add to the comfort of your drive. Manufacturers get very specific with the way they build sedan suspension systems. Tires, shocks and struts, and the necessary parts attached to the suspension system can be fine-tuned to offer you greater performance.

Engine – another part of life expectancy is through engine performance. With a simpler system and fewer parts, it’s easier to maintain. A standard pickup truck is usually going to have a straightforward engine compartment where fewer things can go wrong. With a sedan, manufacturers install all kinds of features to improve performance. With a turbo or supercharger, the parts can be more fragile and complicated, which can also make them more unreliable in the long run. If it’s harder to get replacement parts, you might be without your vehicle longer while it’s being repaired.

Comfort – what are you looking for in a vehicle? Do you want something to haul kids to and from school and activities every day of the week? Are you looking for a vehicle to get you around town? Or are you looking for something to take into the mountains each weekend, satisfying your desire to get away from it all? Trucks are made for hauling. If you wish to tow your boat, camper, or trailer to take advantage of all Colorado has to offer, a truck may be the perfect choice. Sedans work better for urban driving, when comfort and safety are your biggest concerns.

Maintenance – for whatever vehicle you drive, maintaining it will ensure you get the longest life possible from the moment you drive it away from the lot. The key to longevity is being on top of the maintenance schedule established by your car’s manufacturer. It starts with small things like oil changes and rotating the tires. It continues with inspecting the major systems – i.e. brakes, transmission, suspension – regularly to ensure they are in good working condition. Be proactive with your maintenance and your car will be there for you.

What will you pick – sedan or truck?

Luckily, there’s a place for both sedans and trucks in our lives. In fact, many families choose to have both to take care of all their needs.

Whatever you drive, with a regular maintenance schedule, you’ll ensure it lasts for years.

How can we help you keep your vehicle in top condition?

What The White Smoke From The Exhaust Means

June 7, 2022 by Denver Express Car Care

Car maintenance is a little bit timing when to bring your vehicle in for inspection, and a little bit noticing the signs your car makes when it’s warning you of potential problems.

One of the things you never want to see is smoke pouring from the exhaust, regardless of the color. This signifies a deeper, internal problem, and suggests something is wrong. In general, a cloud of thick white smoke indicates a major issue needs to be addressed quickly, or risk something as serious as a blown engine.

Understanding the exhaust system

Before we analyze what smoke coming from the exhaust pipe might mean, it’s important to understand what it is and where it comes from.

Essentially, your vehicle’s engine needs four things to work:

Fuel
Air
A spark
Timing

Fuel is the basic lifeblood of keeping your vehicle working. Too much, and it runs rich. This can waste fuel, but can also eventually damage the engine. Too little, your engine will struggle, or not run at all.

Air mixes with the fuel, which causes it to flow either at the perfect level, or can cause it to run rich or lean. As the two mix, it combines with a spark to ignite the fuel and start the car. This needs to have the right timing to ensure the engine runs efficiently.

This timing affects how much emissions your engine emits. As your car ages, the process becomes less efficient. Older parts can mean each process is just a little off. That’s why older cars have less rigid emissions standards than newer cars.

What The White Smoke From The Exhaust Means

What normal exhaust looks like

The exhaust pipe is there to pull emissions from the engine compartment and release it away from your vehicle. The gas coming from your tailpipe should be clear. On a cold day, the moisture in the emissions can sometimes look like a thin, white cloud.

That’s because gas moves through a process to clean it before it’s released into the air supply. The catalytic converter is an exhaust emissions control device that converts the toxic gasses produced by the engine, and transforms into less harmful pollutants by changing their chemical structure.

If you see something other than gas and air moving from the tailpipe, which has a clear visual appearance, you’ll notice it as smoke. A thick plume of white smoke from the exhaust comes from either water or coolant burning.

Water or coolant can sometimes leak, moving into the combustion chamber as your vehicle operates. It can move through cracks in the cylinder head or engine block, or if your vehicle is experiencing a blown head gasket. Any of these indicate a major repair.

White smoke is pouring out of the exhaust pipe … now what?

White smoke is a clear indicator of a bigger problem. The more you drive your vehicle, the more extensive damage may occur inside the engine compartment. Continuing to drive with a crack in the cylinder head, engine block, or coming from a blown head gasket could lead to further damage, contamination, or possible overheating. Drive too far under these conditions and you’ll have to replace the engine to get it operational again.

Another way to check where the problem originates is by checking the coolant level. If it’s low and you don’t see coolant leaking anywhere else in the engine compartment, it supports the theory that there is a leak in the engine block or head gasket. Once this is cracked or blown, replacement is the only way to repair.

Q&A – Common questions we get about white smoke from the exhaust

Q: Can low oil be the root cause of white smoke?

No. If oil somehow makes it into the combustion chamber, you’ll see a blueish smoke emitting from the tailpipe.

Q: What if the smoke looks black or gray instead of white?

Each color indicates a different problem. Black smoke can mean too much gas is burning, the air filter may need changing, or the fuel injectors may be clogged. Gray smoke is often caused by burning excess oil or a crankcase ventilation valve malfunction. With an automatic, gray smoke can also be a sign of a transmission fluid leak into the engine.

Blue smoke has a few causes. It could be motor oil burning in the fuel system, valve seals or piston rings breaking down. Cars with high mileage are also prone to emitting blue smoke. If you notice blue smoke, watch it for a bit. If motor oil is accidentally spilled onto the engine, it may look blue as it burns off. If it disappears right away, it’s probably nothing.

Q: What is in the exhaust that makes it so bad?

Exhaust gasses come from the combustion process inside the engine. As it operates, it produces carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxide, and hydrocarbons. Carbon monoxide is poisonous and needs to be directed away from the vehicle. The catalytic converter’s job is to convert it into carbon dioxide.

Q: What about bad spark plugs? Can they cause white smoke emissions?

No. Spark plugs are used in the ignition system, but they don’t cause white smoke. Spark plugs have their own symptoms if they’re going bad.

Q: What if smoke only appears when climbing a hill?

That can be common here along the Front Range, especially if you regularly pull heavy loads into the mountains. It’s almost always darker smoke, ranging from dark gray to black. The usual source of the problem is the carburetor. If the carburetor sends more excess fuel into the system when the engine is already stressed, it can create a puff of smoke. If this is the only time you see it, there’s nothing to worry about.

Q: What about electric cars? Would the same problem exist with electric?

Exhaust gasses are produced with combustion engines. Because electric vehicles run on a battery, it won’t produce exhaust. In fact, electric cars won’t have a tailpipe on their design.

Do you have white smoke coming out of the exhaust?

If so, it’s time to bring your vehicle in for servicing. Different shades of color will mean different things. But if you continue to see smoke of any color, it’s an alert that something is wrong.

To reduce higher repair bills, coming in sooner will catch the problem early, and hopefully prevent it from escalating over time.

Why Your Battery Light May Come On While You Drive

June 4, 2022 by Denver Express Car Care

On most days, you slide behind the wheel, turn the key, and start your day. Your car starts. Everything works well. You move throughout your day without thinking about how well your car operates.

On some days, you start the car and instantly are alerted to an issue. Maybe it’s a noise, or a sound.

It takes a lot of power to start your car and bring the entire system up and running. That’s where you’ll notice most inconsistencies with your vehicle.

Yet problems can begin at any point during your drive. What if you’re moving down the road and the battery light comes on while you’re driving? What does it mean? What should you do?

How a conventional battery works

While the sale of electric cars is increasing, most drivers on the road today still use conventional vehicles. That means most vehicles are still powered with a conventional car battery.

Car batteries are used to store energy to keep the car and its accessories running. Batteries use chemical energy to start, and to recharge during operation.

When you insert the key or push a button, it signals the battery to switch to “on.” The car battery converts chemical energy into electrical energy, and delivers it to the starter to turn over the engine.

The standard car battery runs on 12-volts of power. If the battery’s voltage drops, it impacts performance. It can change the way your car runs as you drive down the road. It can also show up in the accessibility of your vehicle’s accessories. Ever had a problem with the radio working, or the headlights dimming? That’s a clear indicator you have a problematic battery.

Why Your Battery Light May Come On While You Drive

What it means if the battery light comes on while you drive

It takes a lot of power to start the engine. It’s when you’ll most likely notice a problem with the way your car operates.

Yet things can also happen as you drive down the road. If you notice the battery light turn on your dashboard, you could be dealing with multiple issues:

A failing battery
Corroded battery cables
A faulty alternator
Damaged battery cells
A loose battery cable
Defective wiring in the car’s charging system

Most problems start small and escalate over time. Paying attention to how your vehicle operates can alert you to minor issues before they become full-blown problems. The battery light is an indicator of the onset of a problem. It could be something small or several issues at once.

If the battery light comes on and stays on, there’s a problem with its performance. If left unaddressed, your battery can run out of power while you’re driving. And that can impact safety and performance.

What can you do?

It’s only natural to want to troubleshoot an issue before you bring it in for a full inspection. If your battery light comes on and stays on, there are a few things you can check before scheduling an appointment. Minor issues can include:

Loose connection – your car goes through a lot as you drive. Connections can jiggle loose, causing your battery to lose full power. Check to see if the cables are still properly attached to the battery. A poor connection can cause a short within the system, illuminating the battery light.

Dirty battery – driving can cause a whirlwind of dirt, debris, grime, chemicals, and other materials to settle underneath the hood. If your battery is filled with dirt or grime, it can impact the connection, and illuminate the battery light.

Corrosion – chemicals or pollutants can come from the exhaust system or spray up from the road. If it accumulates on the top of the battery terminals, it may result in corrosion. This is more common in the summer months, where heat is prevalent.

When you clean your car, pop the hood and look underneath. If you notice dirt, grime, or corrosion forming on top of the battery, you can clean it and ensure the connections are in place. But if you do these things and the battery light is still displayed on your dashboard, the problem is more serious and requires a mechanical inspection.

Is it safe to keep driving?

If you’re driving and your battery light turns on, it’s alerting you your car is unsafe to drive. Because it’s illuminated because of a faulty alternator, battery connection, or some other mechanical problem, it’s wise to have it inspected as quickly as possible.

Safety is everything. Find a safe spot to pull over, then further assess the situation. Is it difficult to steer? Do you notice other compilations with your drive?

If it impacts your power steering, it can be difficult to drive. That makes it unsafe for you to be out on the road, putting you and other drivers around you at risk.

If you are close to home, or can drive your car in to see one of our mechanics, we can assess the situation and get you back on the road. Driving the car may put you in danger, so it’s important to get it checked out before you start driving once again. Keep in mind that once you turn the engine off, you might not have enough battery power left to start it back up. Ensure you’re in a safe place before you flip the switch and turn off your vehicle.

To get the most out of what’s left in the battery, reduce all accessories to ensure full energy is going to the essentials. Turn off the heater or air conditioner, don’t use power windows, unplug your devices from the charger, and flip the radio to the off position. Keep an eye on the temperature gauge, as engine overheating may be a further sign of charging problems.

Have you experienced problems with your battery light coming on while you drive before?

Preserving Your Truck’s Value With These Maintenance Tips

May 28, 2022 by Denver Express Car Care

Owning real estate adds to your balance sheet, providing you with an item that appreciates over time.

Vehicles rarely work that way. Most new cars and trucks start to depreciate from the moment you drive them off the lot.

Yet there’s a lot of wiggle room for what your vehicle will truly be worth when you try to sell it. If you own a truck, preserving the value starts by performing regular maintenance and keeping it in the best condition possible throughout its life.

But what does that mean? How do you maintain your truck to preserve its value, ensuring you get top dollar when it comes time to sell?

This is what makes the most difference in keeping your truck in top condition.

Schedule oil changes regularly

Some basic maintenance items are more important than others. You can add “oil change” to this list.

Regular oil changes fall right behind “keep fuel in the car” as a fundamental need to keep your truck on the road. Yet many drivers “forget” and wind up with problems because there isn’t a direct reminder system built into your car. (Outside of your car seizing if it no longer has motor oil!)

Preserving Your Truck’s Value With These Maintenance Tips

Motor oil provides lubrication to many of the internal components within the engine compartment. To avoid damage and keep the engine running smoothly, it needs fresh, dependable motor oil present every time it runs. Today’s modern vehicles don’t burn oil the way they did a few decades ago, but trouble will arise if oil isn’t provided at necessary levels. It’s the lifeblood of the modern day vehicle.

There is confusion about what oil changes look like in a truck. While the 3,000 mile rule is in place for cars, it’s not as steadfast for trucks. The best way to find out what’s best for your truck is to read your owner’s manual and abide by manufacturer’s guidelines. Today’s trucks often need changing about every 5,000 to 7,000 miles.

Monitor your tires

If you want to extend the life of your pickup truck, give the tires a little TLC along the way. This goes beyond replacing them when they’re worn down.

Trucks usually wear each of the four tires down in different proportions. Front tires may wear differently than rear tires. And it often depends on the type of driving you do. Do you head off-road? Or haul heavy loads? All of that can impact the wear of your tires.

In general, manufacturers recommend rotating your tires every time you schedule an oil change. This provides a more even wear process for each of your tires, and extends the life of a set of four to maximum levels.

You should also check tire pressure regularly to prevent under and overinflation. Underinflation can lower the flexibility of the tire, making your vehicle more squirmy when you corner or come to a halt. Overinflation can ultimately wear the inner tread faster than the outer tread, creating less contact with the road. Both put you at risk and increase your chances of an accident.

In addition to rotating the tires regularly, you should also balance and align the tires every other oil change to ensure ultimate control.

Keep your car clean, inside and out

Here in Colorado, a dirty car can impact more than the paint. If contaminants and chemicals accumulate on the undercarriage, it can break down various components and wear out systems before their time.

Have you ever seen a “brand new” truck that’s actually a decade or more old? Chances are it was owned by someone who took “cleaning” seriously. Washing it regularly ensures the paint isn’t harmed by chemicals eating away at the paint. Waxing the exterior is also a great way of sealing the paint from the harmful effects of the environment. And we have a bunch of them here in Colorado’s climate. Those UV rays will stay at bay with a fresh application of wax.

Don’t stop cleaning once the outside is done. The inside is equally important. It’s a great way to keep the interior finishes looking their best, and prevent rapid deterioration of vinyl, cloth, or leather seats.

Once the finishes are clean, continue by popping the hood of your truck and keeping the filters clean. Both oil and air filters on a pickup truck are a crucial part of truck maintenance.

The air filter is critical because it traps dirt and prevents it from moving into the engine compartment, causing it to lose efficiency and functionality. A clean air filter also helps prolong items like spark plugs and ignition, to ensure your car runs smoothly every time you drive.

If preserving the value is important to you, say “yes” to a new filter every time you schedule an oil change. It’s an easy way to keep it running efficiently every time you drive.

Don’t wait for a battery to die, replace it instead

Batteries typically have a lifespan of 3 to 7 years. But if your truck takes you everywhere from off-roading to hauling heavy loads up the mountain, it’s better to err on the side of replacing the battery frequently.

If the “check engine” light pops on, it could be for many reasons. An inspection will allow a mechanic to hook your truck up to a diagnostic machine and find out right where the problem lies. If the battery is weak, it’s good to replace it before it leaves you stranded.

You can also perform a physical check from time to time. Do you notice buildup on top of the battery? Does the case look as if it’s swollen? Do you see spots of corrosion? All are good indicators of a potential problem with the battery.

Batteries often quote several years of life, but once you move into the lower spectrum, it’s a good idea to have it tested regularly as it continues to age.

What do you do to preserve your truck’s value?

When in doubt, schedule an inspection. Allowing a certified mechanic to evaluate the various systems and pinpoint where problems lie is the easiest way to keep it running for years.

Maintenance Tips For Making Your Car Last Longer

May 21, 2022 by Denver Express Car Care

Today’s car prices are creeping higher and higher. A recent survey showed the average sticker price has exceeded $47,000.

Investing that much money in a vehicle is a significant hit to your wallet. It’s not something you want to do on a regular basis. Protecting your investment could make a difference between a well functioning car for 100,000 miles, or pushing it to 200,000 miles and beyond.

Maintenance tips to make your car last longer

To make your car last longer, it requires regular maintenance to keep it working well. It doesn’t take a lot of work. Just common sense items that ensure it’ll keep working its best for years to come.

Keep your car protected from the elements

Driving in Colorado can be tough on a vehicle. Winter brings sub-zero temperatures, ice and snow pelting the finish, and chemicals splashing up on the undercarriage from the messy streets. Summer brings intense heat, dust storms, and hail, pelting the finish.

In order for a car to continue to run well, it has to look good too. A dirty finish is an indicator of caked on dirt, grime, and chemicals. All of that can rapidly deteriorate a car’s frame and body, and impact many of the systems that keep you safe.

Maintenance Tips For Making Your Car Last Longer

Take the time to wash your car by hand. It keeps the paint intact and won’t scratch the finish. Wax the paint occasionally to ensure it stays protected from UV rays.

Don’t forget the inside. Clean it out regularly to keep the seats looking their best. If you install mats on the floorboards, it’s easier to keep them clean.

If possible, park in a garage. Parking indoors reduces exposure to harmful elements, and keeps your car looking and running better for the long run.

Follow a maintenance schedule

To stay healthy, you schedule regular checkups with doctors and dentists. You eat quality food. You avoid harmful scenarios.

Treat your car in a similar manner. Instead of waiting for a problem to arise, take action instead. If you haven’t thumbed through your owner’s manual, spend some time getting more familiar with your car’s systems. Manufacturers make suggestions on when to bring your vehicle in, and how often you should replace fluids and other parts.

Instead of waiting for them to wear down, if you stick to a timetable for replacing items like a timing belt, spark plugs, or hoses, it prevents expensive repairs when things go wrong, and reduces the likelihood of you being caught off-guard. It reduces the chances of you being stranded by the side of the road.

Change fluids frequently

Cars use a variety of fluids for lubrication and to ensure smooth operation. Some you’re used to changing and adding regularly – we’re programmed to replace motor oil every 3,000 miles. Others we may not think much about – when’s the last time you thought about transmission fluid?

AAA surveyed auto repair shops and found that 88 percent of drivers missed brake fluid maintenance, and 35 percent are behind in motor oil changes.

Fluids keep your vehicle operating well. Without fresh, clean fluid, it wears down, accumulates impurities, and allows debris to infiltrate the system. If you haven’t had a fluids check, or aren’t sure when many of them were last checked and replaced, a maintenance visit would be beneficial to ensure your vehicle is operating well.

Say yes to an air filter

It’s easy to overlook the little tasks, but they often cause the biggest problems.

Did you know your engine consumes a lot more air than gasoline? Its performance depends on a careful mix of airflow and fluid to ensure it works correctly no matter what you experience on the road.

The air filter is designed to keep that airflow as clean as possible, keeping dirt and debris outside of the engine where it can wreak havoc over time.

Your owner’s manual will suggest how often you should replace your air filter. Especially in situations where it may err on the side of being dirty, changing it more frequently will never hurt.

Drive as if your car depends on it

We all get busy. We rush from home to work, trying to fit in as many errands as possible. It’s easy to forgo washing the car, push back on how frequently you change the oil, and allow stuff to pile up in the back seat. When you’re late, you push the accelerator to the floor, trying to make up for lost time.

Yet driving your car like you’re in a road race is hard on your car. High speeds can put your braking system at risk as you pounce on the brakes, wear down your tires before their time, and impact the efficiency of your vehicle. Strong braking will rapidly deteriorate your brake pads. Coming to hard stops puts unnecessary wear and tear on your tires. And quick acceleration when your engine is cold can harm parts throughout the system.

Practice better driving not only for the wear and tear of your vehicle, but also for the safety of you and your passengers.

Fix the little problems

We’ve all heard a funny noise coming from somewhere in the engine compartment, and ignored it until we have “time.” That’s the fastest way to allow little issues to grow into big problems.

Cars are designed with warning signals built into all major parts and systems to give you a chance to repair them before they increase in severity. Technology has made it easier with dashboard diagnostic icons that light up when sensors are alerted of a potential problem. When these lights illuminate, it’s a signal to pull in for servicing as quickly as you can.

Rattles, squeaks, hums, bangs, and even smells are often signs of potential problems. Pay attention, and your car will thank you by providing a longer life.

Following a few maintenance tips will make your car last longer

Being proactive means keeping your car in the best possible condition for as long as possible.

The easiest way is to schedule maintenance visits regularly to ensure every system is working well. Notice noises and smells. Question if something doesn’t feel right about the way your car is operating.

It’s the best way to ensure a long life for 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.

7 Maintenance Tips For Keeping Your Car’s Engine Running Smoothly

May 14, 2022 by Denver Express Car Care

According to a new report, today’s average car price is just over $47,000 and continues to rise.

When you invest in a car today, keeping it running well is top priority. It costs enough for monthly payments and insurance fees, who needs the added expense of repair bills?

The adage of “an ounce of prevention is worth a pound of cure” applies to keeping your vehicle running smoothly. The engine is at the heart of your car’s operating system. While you might not think much about your engine while moving down the road, you will if it starts making noises, or when the drive isn’t as comfortable as it once was.

Engines need maintenance too. If you keep your engine in good operating condition, it will provide you with years of service. Ignore it, and you’ll pay for it many times over.

What can you do?

Start with an oil change

Changing the oil is drilled into every driver from the moment they get their license. There’s a good reason for that. It’s the lifeblood of your car.

When you change the oil regularly, you’re providing fresh, high-quality fluid into various engine parts, protecting them from potential danger. Oil keeps parts lubricated so they won’t overheat.

7 Maintenance Tips For Keeping Your Car’s Engine Running Smoothly

Most repair shops and oil changing stations will recommend changing oil every 3,000 to 5,000 miles. Check with your car’s manufacturer for specific guidelines. Err on the side frequency. It’s better to ensure your vehicle is operating with high-quality fluids rather than allowing contaminants to reside inside. Age of the motor oil matters just as much as mileage if you work from home and rarely drive.

Change out the oil filter when you add new fluid. The oil filter collects dirt and debris and prevents it from circulating back into the engine. This ensures motor oil runs freely through the system, and won’t clog up because of contaminants.

Keep the cooling system in good condition

The cooling system includes the radiator, thermostat, water pump, and coolant. The easiest way to prevent your car from overheating is to ensure coolant is flowing through the system, protecting the major components.

Coolant circulates when the thermostat determines enough heat is in the system to start cooling it down. The water pump pushes coolant from the radiator to the engine block, then back down to the radiator to be cooled once again.

You can check the coolant levels by looking at the coolant tank underneath the hood. It’s a clear tank with green or orange liquid. You can also bring it in for an inspection, and we’ll ensure your coolant levels are topped off.

Check the air filter

Just like a dirty air filter won’t allow proper flow of motor oil throughout the engine compartment, an air filter won’t operate correctly if it’s clogged with dirt and debris. Air filters keep things like bugs, dirt, and leaves from circulating through the air supply as you drive from making it into the engine. Depending on how you drive, the air filter can last a long time, but if it’s allowed to get too dirty, it will impact your engine in several ways. It stops airflow and lessens oxygen needed for the engine to function correctly. It decreases efficiency, which can also reduce your gas mileage. If it’s allowed to get too dirty, it can block the system and cause irreparable damage to your engine. If you’re getting your oil changed regularly anyway, have the technicians look at the air filter to ensure it’s clean.

Check for leaks

One of the benefits of parking in a garage, driveway, or parking spot is you can pay attention to potential problems. As you pull away, look to see if there are any fluids on the ground. The two main fluids you want to ensure aren’t leaking from your vehicle are motor oil and coolant.

The engine is constantly under pressure, with extreme heat forming as you drive. Over time, parts wear out, rubber hoses can crack and break, and they can cause fluid to leak and pool when your car sits for a while.

You can also pop the hood from time to time and see if anything is pooling near the engine compartment. Take a whiff – some fluids have distinct smells. If you do notice fluid, note its color. Motor oil will be dark brown or black. Engine coolant will be green or orange. Automatic transmission fluid will be red or brown. Power steering fluid will be reddish-brown, or darker as it ages. Brake fluid is clear when new, but will turn darker brown over time.

Follow up on all dashboard lights

Dashboard lights illuminate for a reason. While it’s easy to ignore them, they light up to give you ample time to take action.

The check engine light turns on frequently, and warns of a variety of problems, including alternator, battery, or even temperature problems. The best way to find where the issue originates is to bring it in for a diagnostic test.

Replace the fuel filter

The fuel filter is similar in function to the oil filter. They both filter out particles in the fluids they use. Where an oil filter filters particles out of engine oil, the fuel filter takes particles out of the fuel. Fuel filters keep the fuel source cleaner, giving your system better energy to operate with. This can impact your fuel efficiency too.

Change spark plugs

Spark plugs and wires run from the distributor to the cylinders, sending an electrical current to the spark plugs to ignite the fuel. They are used every time you turn your vehicle on. When they get too old, they cause your engine to run rough. Most manufacturers suggest to change them every 30,000 miles or so, but a technician can run diagnostic checks to determine if it benefits you to change them now.

What do you do to your car to keep it running smoothly?

Regular maintenance helps protect your vehicle as well as keep your repair bills to a minimum. Is today the day you give your car an inspection to ensure everything is working well?
