Buying Auto Parts or Visiting a Mechanic – Which Is Better?

February 24, 2021 by Denver Express Car Care

No matter what type of vehicle you own, you’ll eventually have to replace a few parts to keep it running. Whether it’s a can of oil, a new belt or hose, or replacing an entire system, you have a choice:

Buying auto parts yourself and handling the fix yourself
Visiting a mechanic and letting an expert handle the repair

There’s never a right or wrong answer every time. It depends on your knowledge, your skills, and how much time you have to invest in the outcome.

Buying auto parts may seem like a great way to save money. But so much can go wrong.

There are no guarantees or warranties to help you down the road

There are two scenarios at work here.

Let’s say you buy the auto parts necessary to repair your vehicle. The part itself may come with a guarantee, but it often is limited to the part; it will not cover a potential problem when you install it yourself. A manufacturer can’t take that risk – what if you install it incorrectly? It’s limited to what you spend on the part itself.

Some budget-minded drivers attempt to buy parts at a low cost, then take them to a mechanic in an attempt to counter this problem. In this case, it depends on the mechanic helping you out.

Mechanics often won’t use auto parts supplied by the driver because they can’t guarantee the parts are in good working order. This is their reputation on the line. They don’t want to be held liable for using a part that simply won’t work.

An expert will want to take control over the entire situation, to ensure your car is safe as you drive away.

You might not buy the right equipment

One trip to the auto parts store will tell you there are dozens – hundreds – of parts for your vehicle, and when it comes right down to it, they all look the same.

The size may change slightly. Ratios may be off. Parts often vary from make, model, and year.

Imagine ripping your car apart, running to the auto parts store, buying a part, and coming home only to realize it isn’t the right part. Rinse. Repeat.

In some cases, you might not have the right tools for the job either. Different parts have different installation methods – do you have the right wrench?

It’s a matter of time, expertise, and money. Bringing your car to a mechanic will get the job done the right way. Trying it yourself is always a hit or miss at best.

Are you convinced visiting a mechanic is in your best interest?

Want your visit to run smoothly from beginning to end?

Communicate clearly

A mechanic can’t guess at what’s wrong with your car. They don’t drive it every day like you do. Instead, they rely on you to help them determine where the problem is.

Whether you’re bringing it in for a routine checkup, or have a larger problem that can no longer be ignored, spend a few moments creating a list of the things you want the mechanic to check out. Even if you aren’t sure if something is a problem or not, a working list will help a mechanic get to the root of the problem. Noises, smells, rattles, leaks, sensations – even if it seems to be little, it’s better to bring it to a mechanic’s attention to help determine where the problem is.

Be prepared

Cars cost money to operate. Too often, drivers attempt to ignore problems until they become so bad they can’t drive. That ends in a very large bill repairing multiple problems and big-ticket items.

Often, a regular maintenance schedule can find problems as they start, and make minor repairs that will keep your car operating well for the life of the vehicle. Still, cars will eventually need larger services, such as brake replacement and new tires. If you understand how each system is wearing on your vehicle, and you monitor it as you drive, you can save for the larger repairs.

Your car isn’t a storage unit

Today’s vehicles are bigger than ever. That means we see many drivers come in that use their vehicles as storage units. There are golf clubs in the back, boxes stacked from bottom to top. There are leftover papers everywhere, even a stroller tucked behind the front seat.

Trouble is, in some cases, a mechanic will have to remove those items to get where they need to be.

All of that extra equipment adds weight to your vehicle. That might impact the overall quality of the repair. While you might need some of it for your weekly trips and errands, before you bring it into the shop, spend a few minutes decluttering it for your repair visit.

Trust the mechanic to do their job

While you may know how your vehicle drives from day to day, a mechanic is trained to find where potential problems lie, and understands how to fix them. Tell them your concerns, even give them your list, then let them take over and do their job the right way.

If they have questions, they’ll be in touch. Do they have your cell number to reach you at any point during the repair visit? This can speed up the process, and allow you to make decisions as they come up.

Is it time for visiting a mechanic that can help you keep your car in good working order?

When it comes time to finding the right mechanic, sometimes trusting a local service will ensure you learn how to work with the people, and that they understand working with you.

It gives you a chance to build a team to help you keep your car in as good of condition as possible. No matter what.

Maintenance Tips For Your Older Pickup Truck

February 21, 2021 by Denver Express Car Care

How old is your pickup truck? Statistics show it’s getting older.

According to research from IHS Markit, the average age of a light vehicle has grown to 11.9 years, which has increased by one month from the average set one year ago.

There are a lot of reasons for that, including better technology and quality improvements. If you consider your vehicle to be more reliable longer, why trade it in and bump up your expenditures once again?

Of course, where your money goes is a constant ebb and flow. You may not have monthly loan payments, but the older your vehicle is, the more likely you’ll be replacing parts and servicing your car from time to time.

Add in the fact that more people are looking for high quality previously owned vehicles. IHS also has predicted that the number of light vehicles on the road will jump to 16 years and older will jump 22 percent over the next few years, reaching 84 million by 2023. People are no longer demanding new each time they look for new vehicles. Instead, they look for used. It’s no longer unheard of for a vehicle to be sold multiple times.

Technology and quality assurance may be the starting point for making vehicles better today, but an equal handshake has to go to the maintenance market.

If you want your pickup truck to last ten, fifteen years or more, you have to be forward-thinking on your maintenance routine. Instead of waiting for problems to arise, you have to schedule regular visits and fix minor problems before they explode into larger ones.

Want to keep your pickup truck looking and operating like new for years to come? Here’s what to do.

Start with oil changes

An oil change is one of the most basic services your pickup truck needs. It used to be that vehicles needed oil changes right at 3,000 miles, but times have changed a bit. Thanks to synthetic oils being produced today, some of the latest models are pushing the envelope of how long you can travel between oil changes. It’s not unheard of for manufacturers to recommend intervals between 5,000 and 7,500 miles.

But keep in mind that this is a ballpark number. It also depends on your driving habits. Thanks to our recent staying-in-place orders, if you’re spending more time at home, your pickup truck may take longer to reach the specified numbers. The age of the oil is important too. Our advice is to stick with a schedule – base it on miles traveled or months in service, either/or. That ensures your vehicle has fresh oil running through the various parts and systems, and won’t let you down when you need it most.

Check the brakes

Some pickup trucks are treated as the family sedan. They drive to and from work on paved roads, with the occasional stop at the hardware store for little DIY projects around the house. Others are full-out work vehicles, hauling thousands of pounds all over town regularly. Each of those impacts your brake system in different ways.

Do your brakes feel spongy when you press down on the brake pedal? Are you having to push down farther to achieve the same results? It could be a sign of failing brakes. Part of increasing the longevity of your vehicle is in becoming attuned to how it drives. Pick up on the small feelings, noises, or smells that suddenly change. This alerts you to potential problems, and helps you bring your pickup truck in for maintenance sooner. It can be the difference between a small repair and an expensive overhaul.

Spend time with your tires and wheels

One of the easiest places to keep watch for potential problems is with your tires and wheels. When tires are low, they don’t roll and connect with the pavement as easily. That requires more power from the engine to ensure the proper connection. Next time you stop at a gas station, pull in and check your tire pressure. Inflate them according to your vehicle’s guidelines. You should find the levels printed on a label in the driver’s door jamb, or head online and search.

Do you notice uneven wear on your tire’s tread? Do you notice your car bouncing along, a less comfortable ride than normal, or have your vehicle nosedive when slowing for a stop sign or stoplight? Or maybe your vehicle pulls to the right or left as you’re driving along?

All are warning signs it’s time for a maintenance visit.

Shocks and struts can cause handling problems, which could be dangerous to you and others on the road.

An alignment problem can wear down the suspension system, something that can occur slowly over time.

All of these conditions happen gradually over time. That’s why it’s important to keep an eye on basic things to ensure your pickup truck is running well. Inspect your tires regularly and notice any changes in their tread or performance.

Give your pickup truck regular cleanings

CDOT uses a variety of different products on the highways and roads to keep them drivable all winter long. And while they’ve improved the chemicals they use to lessen the impact on a vehicle’s wear, it’s still a good idea to wash it off regularly.

A good cleaning can remove caked-on dust, dirt, chemicals, and other pollutants your pickup truck picks up from normal driving conditions. It also gives you a chance to see your car in a different light. A clean car makes it easier to spot damage. And if you’re handwashing it on occasion, you can see the little things you might miss otherwise.

Dirt can penetrate through even the tiniest hole or crack. And if it’s left to sit, the damage can penetrate, grow, until it does a lot of damage.

Give your pickup truck what it needs to live a long life

Your vehicle isn’t just an object that’s ready and waiting for whenever you need it. It has value that can last for years if you treat it well.

When you purchase your vehicle, whether used or new, spend some time getting to know your pickup truck on the inside and outside. Then watch, listen, and notice how it drives. Just being aware of how your vehicle moves will allow you to notice things quicker.

That can keep your pickup truck in good working condition for years to come.

Are Suspension Systems Different In Pickup Trucks Than In Cars?

February 18, 2021 by Denver Express Car Care

Since the very first horseless carriage was created, focus has been placed on creating a smooth ride. Imagine the first vehicle hitting a rock or a dip in the road – there wasn’t pavement back when the first vehicle was moving around.

Every bump moved from the wheels into the car, jostling the passengers around.

As more cars were built and sold, more time was spent on keeping the passengers safe, comfortable, and happy. Suspension systems are designed to provide each of these things and more.

What is a suspension system?

The suspension system includes all of the parts in the body of the car that allow it to connect with the road – wheels, tires, brakes – as well as the parts that help each of those systems operate – springs, shock absorbers, and other hardware. A suspension system is designed to support the weight of the vehicle, to absorb the shock that comes up into the vehicle with every bump and movement it makes, as well as provide a pivot point for the wheels. Its ultimate goal is to provide passengers with a smooth ride, while keeping you and the vehicle safe during the process.

A suspension system works to absorb the shock when you hit a bump, as well as to decrease the impact sent up through the axel and into the passenger section. The two are connected, yet through a variety of components, it’s designed to lessen the impact. How this occurs often determines the comfort level of the vehicle. This is where trucks and cars move apart.

Front end suspension systems

Most passenger cars and light trucks on the market today use a front suspension system. This includes a conventional coil spring, a Torsion Bar, and MacPherson Strut systems. You’ll find full-sized vehicles use a coil spring or the torsion bar systems frequently, while struts are more widely used on import vehicles and newer domestic vehicles.

No matter how it’s constructed, all suspension systems are designed for the same function – they support the vehicle to maintain proper wheel alignment, to connect with the road efficiently, and to absorb road shock as it moves up through the tires. How this is accomplished may change from system to system, but the final impact is always the same.

A coil spring system works by supporting the weight of the vehicle on coil springs and controlling impact by spring weight. The springs are mounted on either the upper or lower control arm, which also determines where the ball joint will be placed. The load-carrying ball joint is always on the same control arm with the spring.

With the torsion bar system, the vehicle’s weight is supported by the twisting of the bar. The torsion bar performs the same function from above as the coil spring in the vehicle.

With the MacPherson struts, the shock absorber, coil spring, and axis pivot have all been combined into one strut assembly. The weight of the vehicle is supported at the top of the spring plate, while the shock absorber dampens vibrations as the coil spring controls the ride.

Rear suspension systems

Most read wheel drive vehicles on the road today use a leaf spring and coil spring suspension.

They are designed with a solid axle that has some of the same characteristics as a solid axle front system. But the difference lies in movement – the rear wheels don’t pivot. Because more cars are coming with front wheel drive systems, you’ll also find more independent rear suspension systems. They offer improved performance and better control overall.

With a leaf spring system, the control arms are eliminated. A U-bolt connects the springs to the axle, which in turn connects the spring to the frame.

With a coil spring system, the coils sit on the axle housing on the underside of the vehicle. Movement is handled through control arms.

With an independent rear system, it’s used on a non-solid axle. This means that the vehicle will pivot independently based on suspension movement. This encourages better traction, since the wheels have flexibility in the angles they turn to as the wheels turn and move. This provides better acceleration and braking, and less resistance overall.

While independent systems provide better driving ability, it also adds more wearability to your vehicle. Because the wheels act independently of one another, each side must be aligned to the other, as well as to both front wheels. More parts, more servicing, which ultimately means more cost. But for increased safety, it’s worth the effort.

Car vs truck – what’s the difference?

Every car and truck is designed as the manufacturer chooses to produce it. Traditionally manufacturers used a leaf spring layout for the suspension system because they felt it was the safest for heavy loads. However, rules are always meant to be broken, and many have deviated and tried other things.

While most cars on the road today will use front and rear independent suspension systems for maximum control and comfort, many trucks also move to live axles placed at all four wheels.

It’s the shock absorbers’ job to control the axle’s motion as it takes in every bump in the road. For a truck, this task requires different degrees of control, which requires a heavier duty component the more weight you carry.

Trucks also have other considerations for the way they move. Many trucks need ground clearance and lift kits to ensure they navigate safely over rough roads. That means the suspension system must be longer to travel and up and down with every bump it takes in.

Off-road driving can also increase heat. The shock absorber must be able to dissipate that heat as it’s generated in each of the conditions you may put it through. From hauling to off-roading, the suspension system has to be ready for the job at hand.

When was the last time you had your suspension system thoroughly evaluated, to ensure your comfort and your safety? Suspension systems send out early warning signals about potential problems. Are you paying attention to what your vehicle is trying to tell you?

Your Nose Knows Gasoline

February 15, 2021 by Denver Express Car Care

Each time we fuel up our vehicles, we get a little whiff of gasoline, so your nose knows the smell. There shouldn’t be any gasoline smell in or around your vehicle when you are away from the gas station. When you do smell gasoline away from the gas pump, the causes can range from something simple to something that could be very dangerous.

Let’s begin with the simple causes. It could be a loose or faulty gas cap, or you might be missing one entirely. You may also have a leak in the fuel tank vent hose. These are relatively straightforward things to repair. By the way, because your vehicle has fans that draw in outside air, you may be able to smell these outside gasoline leaks inside the cabin.

Here are some other possible sources of a gasoline smell. You could have a leak in your fuel tank, and these are more common than you might think. Fuel tanks can rot or get punctures by road debris. The tank can be fixed or replaced.

The fuel lines can also deteriorate or be damaged by road debris. Vehicles with fuel injectors have high pressure in their fuel lines, so any small holes or leaks can allow vaporized gasoline to escape, sometimes near hot engine parts. Obviously, this is something that a technician should repair as soon as possible.

Another couple of causes of a gasoline smell? A leak near a fuel injector can also allow small amounts of gasoline to escape. A technician can replace the seals or O-rings if they have deteriorated. Also, you could have gasoline leaking out of your vehicle’s charcoal canister, which is a device that prevents evaporating gasoline vapors inside your fuel tank from venting out to the atmosphere. This will often cause the Check Engine Light to illuminate.

Gasoline fumes and leaks can be dangerous for a couple of reasons; they could be a fire hazard and inhaling fumes can cause health problems. It’s always wise to get fuel leaks checked out at your auto repair center as soon as possible.

Brake Shoes – Here’s What You Need To Know

February 14, 2021 by Denver Express Car Care

When you put on a pair of shoes, you use them to move freely. A pair of running shoes can help you travel far distances, and even dress shoes can take you out for a night on the town.

When it comes to your vehicle, brake shoes serve a different purpose. Not all cars have brake shoes, but they are an essential element for some braking systems.

What are brake shoes?

Brake pads are one of the most common elements of a modern braking system. When brake pads are used, they are squeezed together by a caliper, pushing against a rotor disc, which is how they were named “disc brakes.” It’s the brake pads that create friction – energy – to control and stop a car.

But not all cars use disc brake systems. Some use drum brakes instead.

For a drum brake system, brake shoes are used to slow down a vehicle. Brake shoes are crescent-shaped with a rough material on one side. They sit inside a brake drum, and as the brake pedal adds pressure, they are forced outward, pushing against the brake drum to stop the vehicle.

With the popularity and ease of disc brakes, drum brakes are lessening and are usually found only on older cars. However, some vehicles do include drum brakes on the rear wheels of a vehicle in an attempt to lower the cost of manufacturing.

What are brake shoes made from?

Like brake pads, brake shoes are made from organic and metallic materials, tough enough to survive the friction required for the braking process. These materials are bonded together to keep them from shedding or breaking under intense heat and pressure. This material is packed into the brake shoe, and is created to fit precisely within the brake drum as well as the contact surface of the cylinder pistons.

If your vehicle uses brake shoes, they most likely sit only in the rear wheels. The drum brakes often incorporate the parking or emergency mechanism within the system as well.

What are the differences between brake shoes and brake pads?

Because a disc brake system in general, has more controlled stopping force when braking, they are almost always found on the front wheels of modern day vehicles. However, there are other differences between brake shoes and brake pads.

Braking action – one of the biggest differences between the two comes from the force they use to put braking in action. Brake shoes create force by pushing outward towards the drum. Brake pads squeeze together to connect with the rotor.

Stopping power – even though brake shoes are sized somewhat larger than most brake pads, they require more friction to bring the vehicle to a stop. That’s why disc brakes have increased in popularity, and you’ll find them used at the front of the vehicle, to allow the car to stop sooner with less force.

Lifespan – brake pads tend to wear faster because they are at the front of the vehicle, which absorbs more of the force of the braking process. Additionally, brake shoes are enclosed within the brake drum, giving them more protection from the elements, meaning they won’t rust, corrode, or wear down at the same rate as brake pads.

Service – brake shoes are enclosed within the brake drum, meaning they will stay cleaner longer, and require less maintenance overall. However, drum brakes still require servicing to ensure they are working at their best. In some ways, drum brakes are a more complex system, meaning they are more difficult to replace.

Whether you have disc brakes, drum brakes, or both, none are immune to wear. Typically, you’ll find that servicing brake pads to be a faster job. Brake shoes may also require adjustments over time to ensure they are properly connecting with the drum.

The key, no matter what type of braking system you use, is to have them checked regularly. Your braking system is one of the most important systems on your vehicle – ensure they are always working at their best.

What causes brake shoes to fail?

Brake shoes usually fail for one of two reasons:

They fail from normal wear, caused by friction over time.
They are contaminated. This is usually caused when an axel leaks oil into the drum container.

As the brake shoes wear down, they produce a few symptoms to alert you they are failing.

Noise – like every part of your vehicle, brake shoes will make noises as they reach their end of life. When a brake shoe is worn, it will produce a scraping noise as the shoe contacts the drum. If a brake shoe is dusty, it can change the way the materials connect with one another, producing a squeaking noise instead.

Lack of response – as the brake shoe wears down, it will have to move closer to the drum in order to accomplish the same action. You’ll push down harder on the brake pedal to come to a full resting stop. The longer this goes on, the more dangerous it can be, especially when you reach highway speeds and have to come to a quick stop.

Loose parking brake – because the drum brakes also house the emergency brake, when you notice a loose parking brake, it can be a sign of brakes failing. As the brake shoes become worn or dusty, they may not hold the weight of the vehicle without slipping. Even after you apply the emergency brake, you might notice it rolling. Of course, this could be just a problem with the parking brake. But this provides you with time to get your braking system inspected to ensure the system is working at its best.

What’s your next step?

Whether you use brake pads, brake shoes, or a combination of the two, it’s important to note that neither will last forever.

Have your braking system regularly inspected, especially as you’re nearing the manufacturer’s guidelines on the lifespan of your braking system. If you notice one of the warning signs, it’s another reason to have your braking system checked out.

We’ll help you keep your car on the road, and ensure you have a safe vehicle for you and your family to drive.

How To Improve The Gas Mileage Of Your Pickup Truck

February 10, 2021 by Denver Express Car Care

When gas prices are low, how much you spend filling up your tank each week might not be of concern. But the higher the prices climb, the more aware you are of the vehicle you drive.

On average, today’s passenger vehicles get just over 24 miles per gallon. For light trucks, that number falls to 17.5.

That can be a big deal if you drive hundreds of miles each week. It can cut into your budget very quickly.

Yet a vehicle comes predisposed with limits to the mileage it can achieve. You can’t change that. Right?

Turns out, you can. If you’re looking for ways to improve the gas mileage of your pickup truck, read on.

Regular maintenance is key

Every bump you hit in the road, every mile you put on your pickup truck, every trip you take, adds to the wear and tear of your vehicle. Regular maintenance is the best way to counter problems that arise over time.

This includes getting the oil changed according to manufacturer’s guidelines. It also includes ensuring your tires are inflated to proper levels, and maintaining them so you aren’t driving on under-inflated or poor quality tires.

Check your owner’s manual for the ideal pressure for each tire. It’s also listed on the panel inside the driver’s door. Do not go beyond the maximum pressure, and ensure it doesn’t fall below minimum pressure as you drive. Especially in Colorado’s harsh driving conditions, both can put you at risk for blow-outs and flat tires.

Be aware of aerodynamics

Pickup trucks are meant to haul. That’s why you bought your truck. It’s a workhorse, designed to help you do your job well.

Yet as you’re driving around each day, be aware of how you carry different loads. Would a bed cover help protect what’s inside? It might also provide better aerodynamics as you sail down the highway. Can you avoid roof racks and large items challenging the way you drive? Every item that changes the dynamics of your vehicle has the potential to reduce the way your truck moves.

Stop aggressive driving behavior

Traffic on Colorado roads can be crazy at times. How you approach each drive determines how many miles per gallon you’ll get with each tank of gas. Aggressive behavior means you consistently stop and go, apply the brakes, and waste gas.

Back off the person in front of you and learn to slow down and take it easy. Tailgating won’t get you where you’re going any faster, and it puts you and the cars around you at risk. When you can, use your cruise control to help remain at a constant speed. And slow down and respect speed limits, they are designed to help you achieve the highest gas mileage possible. Plus, it keeps your car safer, which means less risk of accidents and potential servicing issues.

Use the right gas

When manufacturers designed your pickup, they did so with optimal performance in mind. They build systems to accept certain types of oil, and specific types of gas. Don’t skimp on which fluids you select to put into your truck.

If the manufacturer suggests regular, it’s for a reason. Don’t add premium, assuming it will be better for your vehicle. If you select a reputable brand of gas rather than finding the cheapest in the city, you’re also ensuring the gas is high quality and contains additives designed to keep your truck running well.

Stop hauling extras

It’s a pickup truck; why not throw a few extra things in the back? A few sandbags for weight. A toolbox just in case. Pretty soon, you’ve added dozens of additional pounds to your vehicle, which ultimately takes more energy to move around town.

Your pickup came with suggested gas mileage ratings based on how it performs as designed. The more weight you add to it, especially unevenly as things are scattered around your truck, it can throw those averages off. Want an easy way to improve your gas mileage? Keep your truck bed clean.

Stop idling

Most drivers would be amazed at the amount of time they spend idling in their vehicles. You sit on the highway in rush hour, you sit multiple cars deep, waiting for drive-thru service. Instead of spending minutes every day wasting your gas in this manner, pull into a parking spot and go inside instead. In many cases, you’ll be in and out faster, and you’ll save on gasoline in the process.

Plan your route

How many trips, on average, do you take each day? Do you leave your home or office multiple times, stopping by to pick things up, running errands, and driving just to stay busy? Driving multiple short trips each day cuts into your gas mileage.

Instead, plan your trips before you ever leave. Can you drive a loop, completing errands as you go? Can you put off certain trips until you have multiple things to do in one area? Can you create days where you run errands, and days where you stay and work from home or the office? This might even add to your productivity levels.

Pay attention to gauges

Today’s vehicles are more automated and technologically advanced than ever before. It’s easy to ignore those little icons as they light up on your dashboard, or the service messages that dance across your instrument panel. They are there for a reason.

Think of them as an extension of your to-do list. They are a gentle reminder that it’s time to give your pickup truck a little TLC.

Staying ahead of potential problems not only produces a more reliable vehicle, but it also extends the life of your truck.

Are you getting the best gas mileage possible with your pickup truck?

What Is A Turbocharger and How Does It Work?

February 7, 2021 by Denver Express Car Care

Imagine sailing down the highway, a cool breeze in your hair, passing by other cars like they are standing still.

It’s been something of fantasy since the early days of automobiles, pushing them to see how fast they can go and how quickly they can get up to speed.

We’ve even written songs about it. Back in 1961, the Beach Boys immortalized a turbocharged engine by writing the song 409. It was created about a Chevrolet 409 engine, dubbed “Turbo-Fire”, that could move zero to sixty in four seconds flat. That started a revolution in the auto industry, with people demanding more from their cars than ever before. Giddy up 409!

Of course, nowadays, it doesn’t take a street car to add power and control to a vehicle. People don’t want that in hot rods and street cars, they want it in the family sedan as they drive to and from work each day.

When you see an auto advertised as being turbocharged, you automatically assume it has extra performance, more power, and greater speeds. But is that truly the case? What does turbocharged really mean? Is it worth it to add it to the next car you buy?

What is a turbocharger?

You’ll find a turbocharger sitting between the engine and the exhaust. It’s a small turbine that connects both pieces together, as well as to the car’s air intake. The turbine uses the exhaust to spin and force more air into the engine, increasing power as it goes.

Most cars on the road today use an internal combustion engine. As the car operates, it’s the downward motion of the pistons that brings air into the engine cylinders. This air is mixed with fuel, and the vapor ignites and creates power. By pushing your car to higher speeds, you’re not adding fuel to the process as much as you are drawing in more air, which vaporizes more fuel to create more power.

The turbocharger changes that around using an exhaust driven process instead.

How do turbochargers work?

A turbocharger has four main parts to make it work.

The turbocharger resembles a snail. It has an air intake, an exhaust intake, turbines in the front and rear, as well as a hose line for bringing in oil.

The intercooler helps control the temperature of the charged air as it’s forced out of the turbocharger. It uses coolant for control.

The wastegate valve provides a boost of pressure.

The engine’s electrical control unit (ECU) controls the air mixtures and ignition timing, which is different from a standard internal combustion engine.

A turbocharger is designed to give you more power. How much power is a difficult question to answer. Car enthusiasts will tell you they can gain as much as 40 percent more power than average vehicles. However, that depends on a host of different variables. It’s safe to say that car gains will vary.

Is a turbocharger bad for your engine?

The main purpose of a turbocharger is power. If you’ve ever felt like you needed to push your car to make it up a hill, or even get through traffic without feeling a lag when you step on the gas pedal, a turbocharger can give you the added boost you might be looking for.

But keep in mind that by adding a turbocharger, it adds another element of maintenance to your regular needs. A turbocharger makes your engine work harder. A turbocharger increases both the pressure and the temperature in the combustion chamber, which will add strain to all parts involved.

The harder the engine works, the faster it will need repair. And replacement.

Having a turbocharger also works under more extreme conditions. This means there is less forgiveness if you don’t adopt a regular maintenance plan that changes oil and checks pressure periodically. Most turbochargers need higher quality oil, and demand shorter maintenance intervals to keep it working at its best.

Are turbochargers reliable?

According to Motortrend, turbochargers are more popular than ever, with about one in four cars being produced today having a turbo engine underneath the hood.

Is it right for you? Here in Colorado, turbochargers can give you the added boost you need, especially if you drive up into the hills often.

Yet keep in mind that by adding more components to the engine compartment for a turbocharger, you’ll also have more potential for things to go wrong. Each of the parts of the turbocharger – turbocharger, wastegate, intercooler, control system – add more pieces to the engine compartment, which means greater chance of potential error, especially as your vehicle ages.

As with any engine, any vehicle you purchase, the key to keeping your car in peak performance is to adhere to a regular maintenance schedule.

Are turbochargers better at towing?

Since turbochargers add power, it’s only natural to think they would be worth the investment if you plan on towing. Not so.

A turbocharger is great for bursts of power and acceleration. If you pull over and want to jet around the person in front of you, a turbo is the way to go.

Long term power for towing heavy objects such as campers and boats is better left to a heavy duty engine, such as a V6 or V8.

Thinking of buying a used car with a turbocharger?

Before you purchase any used car, it’s a good idea to do a little research first. Check reliability ratings. Does the car require premium gas? Have there been major upgrades to the vehicle because of problems with the turbocharger? A quick search in Google will give you plenty of advice on what other drivers are facing with the vehicle you’re considering.

One of the biggest problems you may find is a turbocharged engine that consumes oil. Check for low oil levels. Ask for service logs. Do you notice a trend that the engine needed a greater amount of oil than average? You can also check for oil leaks. Be aware if you notice a burnt oil smell when you look under the hood.

Of course, it’s also a good idea to bring in any used car before you sign on the dotted line. We can perform a full evaluation and inspect the vehicle from top to bottom, giving you a better idea of potential problems lurking in the near future.

Maintenance Tips Before You Tow a Camper Behind Your Pickup

February 3, 2021 by Denver Express Car Care

Planning your first camping trip of the season? Want to make sure your pickup is in great shape before you add the camper behind?

Towing that extra weight can be a big deal, especially if you are up and down the mountain regularly. Hauling is a big deal. Even newer pickups can have trouble if your vehicle isn’t prepared for the added stress.

Whether you’ve been towing for years, or you’ve just purchased a pickup and camper and are excited about your first trip, it’s important to ensure your safety before you go.

Start with your owner’s manual

It may sound like simplistic advice, but the best place to start is with your pickup owner’s manual. The owner’s manual can tell you things about hauling that you may not know, like the maximum load limit, and any special recommendations associated with towing.

Towing takes a new set of skills. There’s a process for hitching and unhitching a trailer, as well as know-how for how to drive in traffic with the added length and weight of your vehicle. Do you understand the process? If not, you could be putting yourself, your passengers, and everyone around you at risk.

Check your hitch

Whether your hitch is brand new, or you’ve been using it for years, this is something you don’t use on a daily basis. Are the parts still in good shape? Is the connection solid? Be sure to check all light connections, making sure they are visible when you use your controls.

Check your tires

Start with your pickup and ensure your tires have proper pressure, have ample tread, and are weighted and balanced correctly. A lot of drivers pay attention to their pickups, but forget their camper or trailers. It’s equally important to check all tires, as a blowout at any point can put you at risk.

Is your camper stored outside? If it hasn’t operated in a few months, especially sitting here in the Colorado cold, ice, and snow, dry rot and cracking is always a potential problem. Even if your tires appear to have plenty of tread, it’s still a good idea to give them a full inspection to ensure their safety and yours.

Think about potential problems

The good thing about hitting the open road and pulling a camper behind your pickup is you can go wherever the road takes you. The problem arises when you’re in the middle of nowhere and are stuck because you didn’t think ahead.

Do you have a spare tire just in case something happens to one of them? Consider your truck and your camper when you pack spares. Do you have the proper tools – a missing lug wrench could leave you walking for miles. While your extra planning might not be necessary, you’ll be thankful you spent the extra time if you need anything from your aid kit while out on the road.

Always get a maintenance check first

Towing puts added stress on a vehicle. Instead of hoping your pickup will do okay throughout the trip, bring it in for a thorough inspection to ensure your safety while you’re gone. Inspections should include an oil change, ensuring the brake pads have plenty of life remaining, and that all fluids are properly filled and operational. If there are any potential problems, one of our mechanics will bring it to your attention, giving you a chance to fix it before you hit the road.

Ensure hitch is properly supported

According to the National Highway Traffic Safety Administration, nearly 50,000 accidents occur each year because of problems with the hitch.

Some of the most common problems with hitches include:

Using the correct hitch – not only should you use the correct type of hitch for your pickup and camper, but you should also make sure that it works for your vehicles. Hitch balls typically come in three sizes: 1 ⅞ inch, 2 inches, and 2 5/16 inches. Do you have the proper connection between the two pieces? This will ensure you have a smooth drive as well as ensure that one of the pieces doesn’t sit lower to the ground, causing you problems when you hit bumps in the road.

Having a proper hitch attachment – with the correct hitch in place, ensure that the pickup and trailer are properly locked and secured and won’t be coming apart while you travel down the road. You should also ensure that proper connections are made all around, with lights functioning, brakes in place, and mirrors to allow you to see all the way around.

Weight awareness – both your pickup and camper come with weight ratings. You’ll find they list curb weight, gross vehicle weight ratings, gross combined weight ratings, gross trailer weight, and tongue weight, among others. Don’t look at one rating – curb weight, for example – and assume you’re ready to go. This can cause poor vehicle performance, give traction problems, and cause steering and braking difficulty.

Proper weight – just because your set to go with your pickup and camper weight, doesn’t mean it’ll stay that way if you load both vehicles down. A balanced load will also ensure you’re safety throughout your trip.

Change your mindset for pulling a camper

No matter how your pickup handles under normal driving conditions, that’ll change once you add a camper behind the bed. Connecting a camper behind your truck changes everything.

It’ll take more power to get the truck moving, more time to get it up to speed, and a greater distance to stop when you push on the brakes. If you don’t take each of these into account, you put everyone at greater risk.

Driving changes mean you’ll have to be more prepared for all conditions. If you brake quickly, you risk causing both steering and braking to skip, throwing off both pieces’ centers of gravity, and risk tipping your load over. Slow and steady wins every time. That means

Slowing down in congested areas.
Always leave space around you, but especially between you and the vehicle in front of you.
Be aware of what’s happening all around you.
Allow plenty of time for passing, especially as you’re moving through the mountains. Always give yourself plenty of time for the move, and ask yourself if changing positions is really necessary.

Before you head out on your first camping trip of the season, ensure your pickup is in good working condition. Schedule your maintenance visit today.

Ball Joint Boot Replacement

February 1, 2021 by Denver Express Car Care

There’s a little part on your vehicle you may not know about, but when it develops a problem, getting it fixed sooner rather than later can save you a lot of money in the long run. Have I got your attention now?

This part is called a ball joint boot. Ball joints are part of your suspension and allow your front wheels to move up and down and turn left and right. This boot covers and protects your ball joint.

Your suspension is, of course, exposed to nasty stuff getting kicked up from the road. Stuff like rocks, salt, water, dirt, and chunks of asphalt. If all that debris were constantly hitting your ball joints, they wouldn’t last very long. So someone had the bright idea to include protective “boots” that go over the ball joints. Great idea and they work…for a while. Just like every other part on our vehicles, they will need to be replaced eventually.

These boots not only protect against debris but they also protect against heat and friction. Because of this, they must be flexible. In addition to keeping contaminants out of your ball joints, they also keep lubricants in and allow the hot grease to expand. This is vital to make sure metal parts are moving smoothly.

Sometimes the ball joint boots get damaged after constant assault by road junk or temperature extremes. Other times they just get old. Rubber and other flexible materials can eventually just wear out (think of old rubber bands that break because they’re brittle from age). A regular suspension inspection will assess the condition of your ball joint boots. When your Express Car Care service adviser says there’s a problem with one of your ball joint boots, heed the warning. If they have a tear in them and aren’t replaced, lubricant can escape the ball joint and debris can get in and start creating a destructive mess.

Also keep in mind that if a ball joint is bad on one side, the other side might be on the verge of going too. Replacing both ball joints and ball joint boots at the same time saves time and money and just makes sense.

How Do You Maintain Your Car Suspension?

January 28, 2021 by Denver Express Car Care

When you climbed into your car for the very first time, what did you focus on?

The way the seats folded around you, preventing you from jolting and jostling with every bump?
How quiet the car was when you took it out on the highway?
How comfortable you were as you drove at different speeds?

You can thank your car’s suspension for that.

A car’s suspension system is responsible for two things:

Creating a smooth driving experience
Keeping the car under control

This may be an innate structure of every car on the road today, but it is also something that fades over time.

A suspension system is made up of several different components:

Wheels and tires

While not everyone considers tires a part of the suspension system, we’d say it would be hard for a car to handle well without tires in place. Tires protect the wheels as you move your car over every bump in the road. They protect jarring from rattling other pieces of the suspension system loose.

Springs

Every car on the road today has a spring mechanism to absorb large bumps. They are built to take extreme pressure, and to prevent failure in other suspension components.

Shock absorbers and struts

While springs absorb bumps, shock absorbers and struts dissipate the motion and give you a smoother riding experience.

Connections

Every component of the suspension system is placed together with kinks, bushing, bearings, and joints. These connections can be made from metal, plastic, or rubber, and wear down over time.

Steering

The steering system is created from a steering box and a steering column, and allows you to gain control over your vehicle in all sorts of conditions. The type of steering system can change depending on the car you drive, with hydraulic or electric power steering systems being at the top of the list.

That’s a lot of parts!

One rule of thumb that mechanics often use is that soft parts will wear faster than hard. Rubber joints and hoses will need replacing sooner than a metal rod.

Yet every vehicle on the road today experiences driving conditions differently.

Today you might slide on a sheet of ice. A few months from now, you may sit in a traffic jam in the scorching heat. You may take a dip into a pothole at 40 miles per hour. You may hit the speed bumps in your area multiple times each day.

All of that can wear your suspension differently over time.

To keep your car in good condition, it’s important to pay attention to the various systems that make your vehicle operate smoothly. A car suspension system needs maintaining in the following ways:

Check the air in your tires – this is one of the easiest maintenance items. Properly inflated tires help protect the entire suspension system from damage. If they are under-inflated, they hurt handling and performance, and may reduce gas efficiency in the long term. If the air becomes too low, you risk safety while you drive. If you don’t have a computerized system that warns you if your tire pressure falls outside the norm, check the pressure every thousand miles or so to ensure proper inflation.

Check tire tread – as you check tire pressure, check the tread too. An easy test is often referred to as the penny test. Place a penny in one of the grooves. If you can’t cover up a portion of Lincoln’s head, you don’t have enough tread for safety. This means you’re more at risk of your vehicle moving out of control, especially in rainy, snowy, and icy conditions.

Get your wheels aligned – proper alignment means you’ll have proper handling in all driving conditions. This keeps you safely on the road in all sorts of conditions. Check your owner’s manual for guidelines on how frequently you should have your wheels aligned, keeping in mind that the rougher your daily drive, the more often it should be a part of your maintenance routine.

Check power steering fluid – if you have a hydraulic steering system, a mechanic should check fluid levels at every oil change. Power steering fluid is usually changed about every 30,000 miles or so, or you can check with your vehicle’s manufacturer for specific guidance.

Inspect shock absorbers and struts – there are a variety of telltale signs your shocks and struts are failing. If you’ve noticed your car bouncing as you drive, or diving forward as you brake, it’s time for new shocks and/or struts. Different vehicles use different systems; not every car has both shocks and struts. Check with your car’s manufacturer for guidelines on how often they should be replaced.

Have you been in an accident – even minor bumps can shake your suspension system loose. If it was strong enough to put a dent in the body of your vehicle, it’s worth having one of our mechanics check your car over. An inspection will ensure that your car is working the way it should, and will get you where you’re going safely and securely.

Pay attention to where and how you drive – even here in the Denver Metro area, people live and work in different conditions. Do you routinely drive on dirt roads? Is there a pothole-ridden road right outside your door? Do you mostly put on highway mileage, or are stop signs and stop lights a big part of your routine?

Because every component of your vehicle’s suspension system is connected and operates in a unique way, there isn’t a proper sequence of where and when things will start to fail. If one part is damaged, it can quickly accelerate problems, and impact many other parts in the suspension system.

Whether you suspect damage, aren’t sure how long it’s been since your suspension system was inspected, or are planning a major road trip in the coming weeks, make today the day you schedule an inspection to ensure your vehicle is working as it should.
