How Do You Maintain Your Car Suspension?

by

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

How Do You Maintain Your Car Suspension?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.

Steering and Suspension Repair – What You Need To Know

by

Picture driving a luxury car. Your mind instantly thinks of words like “performance” and “efficiency.” How about “a smooth ride”? That’s important too, something an owner of a luxury vehicle demands.

Now picture yourself driving an old truck. You feel every turn, every bump in the road.

Big difference, right? Yet as drivers, we understand that different vehicles are designed for different needs. You’ll experience riding differently in an expensive sports car when compared to an old truck.

But we still have expectations of how the vehicle will perform. You wouldn’t want to take a corner and have your vehicle roll. You wouldn’t want to hit a bump in the road and feel like you’re bottoming out the car. No matter if you’re in the sports car or the old pickup.

Your steering and suspension system ensure balance, stability, and smoothness of the ride. These systems ensure a comfortable ride for you and your passengers. Steering and suspension are also responsible for keeping your wheels on the ground.

How the steering and suspension systems work 

Before we get into the problems your car may face with steering and suspension, it’s important to understand how they work.

Vehicles are built with one of two steering systems: reciprocating ball steering and rack and pinion steering.

Reciprocating ball steering works through a series of links and arms to ensure all four wheels turn together and at the same time. It uses a steering box to control the movement of the steering wheel and steering column, and connects it to the functionality of the wheel movement.

Steering and Suspension Repair - What You Need To KnowRack and pinion steering connects the steering wheel and steering column to a rack, which moves a piston as the wheels turn.

The suspension system uses a series of shocks that connect your car body to the wheels. The suspension system is in control of ensuring your wheels connect with the road and giving you a smooth ride while operating the vehicle. The suspension system utilizes a variety of components, including springs, shocks, and struts that absorb the impact of the road as you drive.

What are signs of steering problems?

While some components can wear down quickly with very little warning, your steering system isn’t one of them. It will almost always give you plenty of advanced warning that something is wrong.

Don’t ignore the warning signs. Ignoring them can result in a system fail, causing an accident that will impact you and the drivers around you. Steering problems include:

Difficulty when turning the wheel – especially if you have power steering, this is one of the first things you’ll notice. It may be a leak in the steering fluid, which helps give you easy control in how easily the wheel turns.

Vibration in the steering wheel – you’ll feel the wheel vibrate or pulse as you drive the car. It could be a steering wheel problem or an alignment issue, which is why it’s a good idea to let a trained mechanic inspect your vehicle.

Looseness in the steering wheel – this is usually caused by a worn steering rack that won’t hold its position.

Vehicle wanders or pulls to one side – worn equipment won’t keep your vehicle on track without extra help from you to hold it in place.

A screeching or grinding noise as you turn the steering wheel – if any noise continues every time you use your vehicle, it’s worth a trip into our service station to inspect it and find out where the problem lies.

What are signs of suspension problems?

Like other systems in your vehicle, the suspension system will have distinct issues as components start to wear and fail. The most common include:

Vehicle that pulls to one side – that’s a sign there are one or more issues with your suspension system. It could be uneven tire pressure, uneven tire wear, poor alignment, or a bad steering rack. This is often caused by driving on rough roads – have you hit speed bumps or potholes especially hard lately?

Feeling every bump in the road – when you start to notice a rough ride, it’s a clear indicator of a problem with your shocks and struts. It gives the distinct feeling of bouncing as you drive on the road. You can test by performing a bounce test – with your car parked, press down on the front end and release. If it bounces back and forth more than three times, the shocks and struts are worn.

One corner of your car sits low – a damaged spring may cause one corner of your car to sit lower than the others. You may also notice a clunking noise as you drive because of compromised equipment.

Braking or accelerating makes your car squat or nose dive – this is a very distinct feeling as you notice this extreme handling.

Difficulty in steering – if you find steering especially difficult, especially when first starting out and traveling slowly, it’s usually a sign of a suspension problem. You may also feel it slipping or difficult to hold onto the wheel. It can be a number of issues, including low power steering fluid or a leaking power steering rack.

Don’t ignore steering and suspension repair

One of the primary reasons why people put off regular maintenance is time and fear of the cost.

Time is always a factor – why pay attention to something that works well when you have a lot of little fires all around you? The best way to keep little fires at bay, avoiding them in some cases altogether, is to stay ahead of potential problems. Regular maintenance will ensure you fix items before they grow in size, often reducing the amount of money you have to invest in the repair.

That also impacts your final cost. Repairing a part limits your financial output. If you ignore a problem – a worn shock, for example – can quickly escalate and cause other major damage to your vehicle. That can increase your cost exponent, also increasing the likelihood of being without your vehicle for days rather than a few hours.

Why Your Pickup Truck Maintenance Won’t Be The Same As Your Car Maintenance

by

When you look at a pickup truck and a car, the differences might seem obvious. But there are distinct differences that separate the two apart.

Vehicles are classified by many different things:

  • Size
  • Weight
  • Design
  • Function
  • Purpose

The difference between a pickup truck and a car can ultimately be brought down to one thing: function. Cars are designed to carry people, not things. Trucks are designed to carry cargo. The emphasis isn’t put on the comfort of the passenger; rather, it’s designed for use and function.

The auto industry has labeled vehicles into distinct categories; your driver’s license lists what you’re licensed to drive. Passenger cars are listed as Class A. Light vans, minivans, SUVs, and pickup trucks are Class B. Medium and large-sized trucks are Class C. Each class has different inclusions and requirements as to what vehicle resides in each category. For example, a truck must weigh more than 8,500 pounds and have features for off-street or off-highway operation. That, of course, leaves wiggle room in the way manufacturers design their vehicles.

The difference between a car and a truck is noticeable. But what about a truck and a pickup truck?

Why Your Pickup Truck Maintenance Won’t Be The Same As Your Car MaintenanceTrucks are designed to carry, haul, and tow. They are designed in similar fashion, with a basic cab and some type of chassis attached to the rear. Pickup trucks are trucks with a separate frame and an open bed. They take a design from each category – cars and trucks – and combine them into one vehicle. Pickups are a smaller version of a truck, designed for multi-use. They are compact, perfect for family use as well as functional enough to use for smaller business.

Pickup trucks have become a mainstay in our community because of their functionality. They can be more useful than a typical car, providing a wide open space to carry just about anything you desire. Yet they don’t sacrifice on comfort, with sometimes luxurious cabs that offer you all the comforts of a car.

A pickup truck might not be big enough to handle the largest of jobs, but they offer a wide variety of functionality for both business and commercial purposes.

It may seem like the two are more similar than not in the way that they operate. They both have tires. They both need oil changed regularly. Yet there are many distinct differences that can impact the way you perform pickup truck maintenance compared with your family car.

Pickup trucks require different parts and tools

When you look at the two side by side – a pickup truck and a car – the one distinct difference is size. Pickup trucks are physically larger. They have more weight. That means the internal parts will be scaled to match the size. Bigger parts also mean larger tools to maintain each of the parts throughout its life.

Try jacking up a pickup truck with a standard jack built for a small, two-seater convertible. You put you, the jack, and your vehicle at risk. Small jacks just aren’t built to handle that kind of pressure.

It’s not just the weight. If you jack up the car to work on a flat tire, the tire itself will be larger too. The weight of the wheel will be more. The tire itself will be larger and more difficult to move. Even the tools you may have on hand for standard car repair won’t work on larger truck parts.

Manufacturers also know pickup trucks are put through more wear and tear every day. They screw nuts and bolts into place tighter to ensure they safely stay in place. Can you get them loose? Can you tighten them thoroughly to ensure they stay safe as you get back to work?

Pickup trucks are used differently

When you purchase a car, you tend to use it for normal city driving (even if you live way out in the country.) You stick to pave roads. Even if you lose pavement and return to a dirt road, it’s still graded and fairly easy to drive. All-wheel vehicles may give you the possibility to drive off-road and visit some of nature’s best. But you still understand the limits, and pay attention to how much roughness you put your car under.

Pickup trucks are designed to handle the pressure of dirty, dusty roads, all while pulling a heavy load. From a trailer to a camper, to a boat, pickup trucks are designed and ready for any job. Of course, you have to pay attention to the payload of what your pickup truck can haul. But even when the two match, that puts a lot more strain on each of the systems within your pickup truck, meaning they need special attention when they head in for a maintenance visit.

Towing puts more wear and tear on your vehicle. Suspension, for example, is a system that takes all the abuse of daily driving habits. But when you’re pulling heavy loads, bumping over rough roads, and doing so sometimes in the worst road conditions possible, it places additional stress on every part of the suspension system, springs, shocks, steering, and driveshaft joints.

Pickup trucks may use different products, but they still need the same care

You know all the rules you learned about regular car maintenance? They apply similarly to pickup truck maintenance too.

Your pickup truck works hard for you every day of the year. It needs oil changed on a regular schedule. It needs tire pressure checked and evaluated several times throughout the year.

When you pull in for an oil change, our mechanics still give your pickup truck a thorough inspection, similar to a car. But we pay close attention to the amount of fluids used, and talk with you about expectations.

Trucks engines are bigger than cars. Bigger engines need more oil, coolant, and other fluids. And in some cases, they even need a different formula of motor oil. It depends on the engine size, and what your pickup truck is put through regularly. We’ll talk with you about the different functions of modern motor oil, and help you make the right choice.

Is your pickup truck operating at peak performance?

A Checklist To Help Keep Your Pickup Truck Running Well

by

In today’s society, most of us can’t imagine life without a vehicle. But for many of us, a vehicle is simply a way to get around. Sure, we buy something we like. We may choose a color we love, get a few accessories we think we can’t live without. But it doesn’t become a part of who we are.

Pickup trucks are a different story. If you have someone in your life who loves their pickup truck, you know this to be true. It’s not just a vehicle, it’s a part of their identity – almost a part of the family. They can’t imagine life without a pickup truck in their lives.

A recent article in MotorBiscuit said it best:

Americans own pickups because they are the ultimate union between the things we love most: utility and freedom. You can race or “mud” your pickup. You can start your own business or move your entire home with a full bed and a trailer hitch. Heck, you can pitch a tent in the bed and go truck-camping. Pickup trucks embody the American dream.

Are you a pickup truck owner? Chances are you see yourself with your truck for a very long time. In order to do that, maintenance will be key. But what do you do to keep your pickup truck running well year after year? Luckily we have a checklist for you. Follow these simple guidelines and your pickup truck will be part of your family for years.

Routine oil changes

A Checklist To Help Keep Your Pickup Truck Running WellOil changes are an important part of any car maintenance routine, but especially for a vehicle you hope to keep for years to come. While you may use your car simply to run around town running errands and bringing the kids to daily activities, your truck may do a variety of different things during the day. Drop the kids off at school, pick up a load of lumber, head out on dirt roads to camp for the night – it can experience a variety of road conditions all in the course of a few hours. Because of this variance, you should ensure the oil is changed frequently to keep all working parts operating correctly. Heavy hauling can deteriorate certain parts quicker than normal driving conditions. Error on the side of getting the oil changed on a frequent schedule.

Battery health

Colorado weather can be considered harsh. It’s a place where it’s not unusual to have multiple days below zero in the winter, and just as many days above one-hundred in the summer. Summer heat and winter cold can take its toll on any vehicle, but especially on a pickup truck that works hard in each season. The inbetween seasons are a great time to check your battery’s health. The best way to check it is by using professional test equipment. With just a quick check, we can help determine how well it’s operating, and give you a chance to install a new one before it leaves you stranded on the side of the road. That’s a big deal if you’re miles away from a mechanic.

Inspect your tires

While your pickup truck won’t survive harsh driving conditions without a proper oil change or a healthy battery, it also won’t do well with poor tire conditions. Tire pressure can drop substantially as the temperatures fall, causing all kinds of handling issues. If your truck can’t gain proper traction, it can put you and everyone around you at risk. In order to to ensure your truck operates correctly under all sorts of conditions, check the tire pressure of all tires, as well as your spare, to ensure they are properly inflated. You can also conduct the penny test to ensure proper tread. Place a penny in the tread of each tire so that Lincoln’s head is facing you. If his hair isn’t covered, it’s time to replace a worn tire. Remember, tires can wear at different levels, so it’s important to test each tire periodically.

Pay attention to visibility

With all that your truck goes through each day, visibility factors can be impacted along the way. While you might wear a dirty truck as a badge of honor, it can impede how well your truck lights up on a dark night. Be sure your lights are working well and that they aren’t caked with dirt, or not working at all. Clean out any grime or insects from the lenses to ensure you have proper lighting control. You should also ensure your heater and defroster are in good working condition. While you may be okay in a cold cab, it’s not okay if your windows fog up and put you and others in jeopardy. Replace worn windshield wiper blades regularly and ensure they work well.

Keeping your pickup clean

While a dirt-covered pickup truck may symbolize all you do with your truck, it can also wreak havoc on various parts and systems in the process. Dirt and dust particles can cause small scratches in the finish. The finish is a protection system to keep water, dirt and debris from penetrating in and causing harm. Removing these particulates will keep this protection in place. An occasional wax job will also create a protective barrier between the harsh sun rays we receive year-round here in Colorado. Think of it as sunscreen for your pickup. You should also pay attention to the undercarriage. Traveling dusty roads can allow dirt to cake to some of the most important systems, including your brakes. Mag chloride, sand, and other winter road treatments can adhere to parts. This is about ensuring every part of your truck stays in good working condition, no matter what it goes through each day.

Find an auto mechanic you can trust

No matter what your busy days entail, the last thing you need to worry about is if your car will be ready for all you can dish out the following day. By finding an auto mechanic you can trust, you can schedule routine maintenance checks to find out where your potential problems lie. That way you can stay ahead of issues that can leave you stranded, or build up into bigger problems down the road. They can alert you to simple changes that will make a world of difference, and keep you on the road. Or off the road if you desire!

If you love your pickup truck, keeping your pickup truck running well doesn’t have to be a difficult process. It starts with being proactive with everything you do.

Thermostat

by

The thermostat is part of your cooling system.  The thermostats in your vehicle perform a similar function to the thermostats in your home.  At home, you set your thermostat to maintain a comfortable temperature range.  Then when your home gets too hot, the air conditioning kicks on or when it gets too cool, the heater turns on.

So your engine also has an optimal temperature range:  warm enough to run efficiently and not so hot as to cause engine damage.  Your vehicle’s thermostat is a valve between the engine and the radiator.  When Denver residents first start a cold engine, the valve (thermostat) is closed, allowing the coolant surrounding the engine to warm up to the proper operating temperature.  As the coolant gets hotter, the thermostat opens, allowing coolant to flow through to the radiator to be cooled.  The thermostat opens and closes to keep the engine within a certain temperature range.

Now thermostats are rated for a specific temperature depending on the engine – not a one size fits all proposition.  Thermostats are subject to normal wear.  Proper operation depends on a special wax that expands as it heats up to open a spring-loaded valve.  A worn thermostat could stick in the open position causing the engine to run too cool.  This is inefficient and could affect performance and fuel economy.  If a thermostat sticks in the closed position, the engine can be subject to the results of overheating.

There isn’t a specific routine for drivers to maintain their thermostat, but maintaining the cooling system by changing the coolant/antifreeze on a regular schedule will make sure the coolant has enough corrosion inhibitors to protect the thermostat and other system components.  Cooling system experts and the team at Express Car Care in Denver recommend replacing your thermostats when you do a coolant flush or exchange.  Also, thermostats usually wear out faster than your hoses, so if a worn hose replacement is performed, replace the thermostat at the same time.

If your temperature warning light comes on, have an inspection of your cooling system right away.  This could be a thermostat.  The thermostat could also be the culprit for Denver residents who aren’t getting hot air when they turn on their heater.

The thermostat is a relatively inexpensive part that stands guard between you and catastrophic engine damage.  Follow your owner’s manual instructions or check with your friendly and knowledgeable Express Car Care service adviser to see if it’s time for a cooling system inspection or service.

Helping Your Truck Run Well As It Ages

by

People don’t buy trucks with the thought of keeping them a couple of years and trading them in for the latest model. Many purchase their pickup trucks with the intent of owning them for years. They become a friend.

But if you want it to last for years while running well at the same time, you’ll have to perform regular maintenance. It’s the best way to keep a truck running well as it ages.

What advice do we have to share on keeping your truck running well? Here’s what we advise.

Keep your oil changes scheduled

This is one of the easiest yet powerful ways to keep your truck running well. Trucks work hard throughout the day, performing any task you ask it to do. In order to keep running well, it takes fluid to ensure each part performs as it was designed. Today’s trucks are technologically advanced, and can operate well with an oil change about every 7,500 miles or six months, whichever comes first. For older trucks or vehicles with higher mileage, change it more frequently. Be sure to get a new oil filter with your oil change as well. Also ensure that you use the right oil for your situation. Your owner’s manual will point you in the right direction. Or speak with one of our mechanics; we can help you decide the right motor oil for your needs.

Make sure all fluid levels are up

Helping Your Truck Run Well As It AgesMotor oil isn’t the only thing your truck needs. While this is the one fluid you should monitor and replace regularly, other fluids need occasional work too. Engine coolant helps keep your engine cool and prevents it from overheating. You’ll find the cap identified by a warning label and illustration to ensure you never open it up while the engine is hot. It should also be checked and filled according to manufacturer’s guidelines. It’s also a good idea to fill up your windshield washer fluid reservoir regularly, and even keep a jug of the cleaner somewhere in your car. The more time you spend on dusty, off roads, the more you’ll need to add to help you drive. While there are other fluids – brake fluid, for example – letting one of our mechanics evaluate your systems will ensure the equipment isn’t compromised, preventing you from driving.

Check your tires

What’s the most important part on your vehicle? While there are many you could argue would be at the top of the list, your tires would definitely be one of them. Think about all your tires go through as you drive. Flying down the highway keeps your truck balanced. Now imagine it driving down a dirt road, as it rotates with every dip and bump you hit. That impacts each tire differently. Rotating the tires regularly ensures even wear over time. While manufacturers have guidelines established, we recommend rotating them more especially if you put your truck through a lot of stress. The front tires will see the most wear, so rotating them periodically will help the tread and extend the life of each of your tires.

When having them rotated, it’s also wise to have them balanced as well. This ensures that the weight of each tire is evenly distributed around each axle. Every time you hit a pothole, or head off-road on a mission, it risks throwing your tires out of balance. Getting them balanced means keeping your tires in better condition, and extending the life of each tire.

Don’t forget about alignment

Do you notice your truck pulling to one side or the other? It’s probably time for a wheel alignment, as driving on rough roads can increase the chances of misalignment. When a misalignment occurs, it creates more wear and tear on the tires. It will also cause poor handling on the road, and decrease your gas mileage. If your truck is out of alignment, it can cause uneven distribution of your truck bed. That means every time you haul something it can place undue pressure on the tires. That can lower tire pressure, and increase the pull. It’s a constant circle of damage that can happen to various parts on your vehicle. Alignments are easy to do on a regular basis, and one of the best ways to ensure your truck is running well as it ages.

Monthly checks

A lot can happen to your truck over the course of a few days. Instead of waiting for a regularly schedules maintenance visit, or waiting until you notice a problem, be proactive in checking things out. A monthly check walking around your vehicle for a visual check will help you notice small problems that can lead to big issues. Turn on your turn signals; do they work? Check to see if your lights are bright and fully illuminated. Do your brake lights work? This is also a time to ensure you have supplies in your truck. Carry windshield washer fluid for easy fill-up. Put spare fuses and lightbulbs in the glove compartment in case one goes out. Having a few extra parts will ensure you never get stuck for something easy to fix.

Change your air filter

While your vehicle can’t survive without fluids, it also needs clean air circulating through the system to function at its best. Over time, the air filter can accumulate dust, dirt, debris, and other pollutants simply from driving on the road. Change out the air filter regularly at least 15,000 miles or more frequently if you drive a lot. It’ll help your engine last longer, and can make your gas mileage more efficient, meaning you’ll save every time you pull into the pump.

Pull in for an inspection today

Just like you see your dentist and doctor regularly to ensure you’re in top health, so to should you bring your truck in frequently to ensure it’s in good condition as it ages. A mechanic can help pinpoint issues to watch for, make suggestions for repair and maintenance work, and keep your truck running in the best manner possible. All of that will ensure you stay on the road for years, and your truck remains loyal and with low maintenance for as long as you own your truck.

Are There Traction Control Problems With Your Car?

by

Have you ever been in a position where your car’s wheels slip, spin, or skid?

It can be a scary experience. You have control over your vehicle, and in a split second, you don’t.

YouTube is filled with videos of people in precarious situations after losing control. They even make television shows about it. But when it happens to you, it’s no laughing matter.

That’s how traction control was created.

What is traction control?

When cars were first created, safety was minimal at best. As more cars found their way to the roads, manufacturers started adding in safety features based on what drivers were experiencing.

Engineers tackled the skidding problems first by introducing antilock braking, or ABS. ABS is an antilock braking system that helps prevent cars from locking up, and improves the steering control process at the same time. While the technology was developed early in the automotive industry, debuting in 1928, it wasn’t until 2013 where the US made it a mandatory inclusion on all vehicles produced.

Are There Traction Control Problems With Your Car?That was the starting point for traction control. As engineers looked at how well ABS controlled skidding, they also played with sensors, actuators, and computer technology to detect and prevent tires from spinning.

Traction control is a safety feature that prevents tires from spinning, allowing maximum connection to the road surface. A traction control system can be turned on and off with a button marked TC, TCL, or an icon showcasing the rear of a car with two skid marks.

Traction control is designed to monitor the speed of each wheel individually, as well as the overall speed of the vehicle. This data is monitored and compared in real time, and when one wheel is determined to be spinning faster than necessary, the system intervenes. The system relies on the sensors of the vehicle, accelerometers, or even leverage satellite navigation systems to track speed. Once detected, it utilizes ABS hardware to bleed off some of the brake pressure to allow the skidding wheel to regain traction. Traction control needs to be about to add hydraulic pressure to control the spinning of individual wheels.

Traction Control Problems

Now that you understand how traction control works, you can better understand traction control problems that can materialize over time.

Problems with sensors responding

One of the most common problems that can develop are problems with the wheel speed sensors. These sensors are exposed to the elements, making them vulnerable to driving conditions. Over time, buildup can occur from dirt, chemicals, and other contaminants that are splashed back underneath the car.

Another common sensor problem is between the electrical connections from the sensor to the computer. If the connection is disrupted, it leaves the traction control system vulnerable to error. And that impacts the drivability of your car.

Warning light

Today’s vehicles are built with technology in mind. Every major system is connected to a monitoring light that illuminates on your dashboard if it senses a problem. Some vehicles have one warning light for both traction control and ABS, while others split it out and have two. Two lights are becoming more common as drivers have the opportunity to turn traction control on and off.

If you notice the warning light turn on and off while driving, it may be sensing a problem with the electrical connections. If the light comes on as you turn your vehicle on, it indicates the system isn’t functioning properly.

Sensitive system

Though traction control offers many benefits, especially to drivers here in Colorado, it can sometimes be a hassle in short term situations, such as leaving a parking space with rutted snow. Some traction control systems are hypersensitive, and turn on at the first sign of a wheel slipping. They reduce power, apply the brakes, and you’ll have nowhere to go. Fortunately, most vehicles have a manual technique of turning off traction control. Then you can revert back to rocking your vehicle back and forth to get it out of the rut. The traction control system can be tested for sensitivity, but in some cases, you’ll have to work with the system when you are in this type of a situation.

Faulty sensors

Like every part on your vehicle, the sensors will only last for so long. Wheel speed sensors are designed to detect the speed of each wheel, noting when one wheel is speeding faster than another. If a sensor isn’t tracking speed correctly, you’ll have to turn off traction control and gain control over your vehicle without using it as an aid. If it’s a problem you notice over and over again, it could be a problem with the sensor.

System problems

Every make and model has different ways of building ABS and traction control into the vehicle. Some systems use hydraulic valves and actuators, while others rely on the electrical system.

Fortunately, our mechanics are trained to work with both types of vehicles. If you notice a problem with traction control, the first step is to bring it in and have us evaluate the entire system. We can pinpoint exactly where the problem lies, and bring it back to good working condition.

The future of traction control

If you’ve recently purchased a new vehicle, you may notice that traction control has an upgrade. Just like ABS hardware and electronics were modified to add traction control to your vehicle, modern technology has provided electronic stability control (ESC).

Depending on the make and manufacturer of your vehicle, it might also be listed as active yaw control (AYC), electronic stability program (ESP), dynamic stability control (DSC), vehicle stability control (VSC), vehicle stability assist (VSA), and more.

What it takes to move from traction control to stability control is more computing power, and a way for measuring the rate at which the vehicle pivots on the center axis. Stability systems help ensure the vehicle goes in the direction of its steering wheel, monitoring its behavior in a way ABS or traction control never could.

All stability control systems use traction control, but the reverse isn’t true. The US mandated that stability control would be included on all new vehicle production starting in 2012.

Simple Answers: Exhaust Service

Question:  My car failed its emissions test -what do I need to do?

Express Car Care Answer:  Let’s get this out of the way…a leak in your exhaust system could be deadly.  If you smell exhaust in the passenger cabin or hear an unusual exhaust sound, get your exhaust system checked and repaired.  This is important:  Carbon monoxide in your exhaust is odorless, colorless and tasteless and can be fatal to you and your passengers, so don’t delay if you suspect an exhaust leak.

There could be several reasons for a failed emissions test, so some diagnostic work is in order.  A common reason is that the catalytic converter has failed.  The catalytic converter removes some of the harmful elements in exhaust.

When a catalytic converter fails it must be replaced, which isn’t cheap, so many people stop there…but the converter failed for a reason.  There may be any number of engine run conditions that led to the failure.  It would certainly be smart to have your technician diagnose the cause so that you don’t end up with another catalytic converter replacement down the road.

Oh, and that check engine light that so many people ignore…it might just be illuminated for a condition that could lead to catalytic converter damage.  Have your service professional get to the bottom of any check engine light situation.

EVAP System Leak, Now What?

by

When you buy an automobile, you quickly learn how it operates and functions. You adjust to the noises it makes. You become attuned to the way it performs. One tiny change – a noise or a smell – will alert you to a potential problem, and give you ample time to have it fixed before the issue escalates.

Luckily, with today’s modern vehicles, it’s not just about relying on your sense of smell or hearing to detect a potential problem. Technology is now integrated into every vehicle, being the internal sight and sound that watches over everything that happens every time you start your car. Every system is calibrated to acceptable levels, and if anything moves beyond those measures, it alerts you with a tiny dashboard light.

The check engine light is one that alerts you to a variety of potential problems. Some can involve minor fixes. Some can be massive system failures – especially if you don’t fix the situation quickly.

An EVAP leak is one of those potential problems that impacts your check engine light. What is it and how do you fix it?

What is an EVAP leak?

EVAP System Leak, Now What?An EVAP leak is a problem somewhere in the evaporative emission control system (EVAP). The EVAPs purpose is to contain any fumes released from gasoline, and prevent them from seeping out and impacting the environment.

The EVAP system is an important part of your vehicle’s pollution control feature, but it also serves another function: it keeps dangerous fumes from entering the cabin of your car.

How does the EVAP system work?

A vehicle’s EVAP system controls fuel vapors from escaping the fuel tank as your car sits and runs. These vapors are collected and condensed before being returned into the fuel tank. The fuel tank is a sealed system that is vacuum controlled and has purge control solenoids for the process.

As the engine runs, a vacuum is used to draw fumes into a charcoal canister where vapors are collected and condensed. As you turn the key, the engine activates a control valve which releases this vacuum into the system. The purge solenoid moves into operation and helps control the vapors, moving them back into the fuel tank.

The fuel tank has a pressure sensor to monitor this supply cycle and ensure it’s working correctly. It’s a continual process, keeping you safe while you drive, but also ensuring your car remains safe as it sits, unused.

What can go wrong with the EVAP system?

When any part of the EVAP system is compromised, it can cause a problem inside the vehicle. If a problem arises with the vacuum, solenoid, or sensor at any time, it will deliver a code to the main computer memory, alerting it to a problem within the system. It illuminates the check engine light to warn you of a potential problem.

Potential problems can include:

  • Gas cap failure – this is one of the most popular shortcomings, due to regular usage
  • Gas cap O ring is damaged
  • Gas tank filler tube is damaged
  • Vacuum feed line leaks
  • Vacuum control valve leaks
  • Vapor tube from the charcoal canister to the tank is damaged
  • The charcoal canister is leaking

Is it safe to drive with an EVAP leak?

While it isn’t dangerous to drive with an EVAP leak, there are several reasons why you shouldn’t.

First, it is potentially harmful to the environment. Every time you drive, your car emits exhaust fumes that contribute to the destruction of the ozone. Without the EVAP fully working, you’re emitting various levels of harmful chemicals into the world.

It also impacts your drive. While you might be able to drive your car with EVAP problems for a while, eventually, you’ll have to undergo an emissions test to update your vehicle registration. An EVAP leak will prevent you from passing this test. The longer you wait to fix the problem, the more potential damage may be done.

Finally, while the EVAP is a closed system, and won’t directly impact your health if there’s a leak in the system, it can impact other comforts of driving your car. A leak can impact the pressure in your gas tank, which can affect your mileage. It’s also something to pay attention to if you park in a closed environment.

Can you pass smog with an EVAP leak?

The short answer is: maybe. It depends on the source of the problem.

In some cases, this may be the first sign you have a problem. A negative test alerts you to the fact your car isn’t working properly.

If you do notice a check engine light before an emissions test, scheduling a maintenance visit to ensure every system on your vehicle is fully operational will help keep your car in good working condition all throughout the year.

Does EVAP system affect performance?

The EVAP charcoal canister valve – the purge solenoid – acts as a switch to move vapor into the engine. If this fails, one of the first symptoms you may notice is a rough ride. You will notice your car running inconsistently when you come to a stop, or while you’re driving at low speeds. If it sticks open, it can create a vacuum leak that impacts your idle speed. If damage to the solenoid continues, it can also lead to your engine stalling out completely.

The EVAP controls vapor. A leak within the system can impact how well your vehicle starts and stays running. Any issue with interrupted internal combustion may cause your engine to stall or refuse to start altogether.

How do you fix evaporative emission system leak detected?

One of the easiest fixes is simply to replace the gas cap. Since broken seals and a loose fit can impact how much emissions are escaping, Inspect the O ring. Because the gas cap is removed continuously when you fill up, it can stretch and loosen over time.

It may also be the vacuum feed line. This line feeds from the engine intake manifold to the EVAP system control valve. Engine heat and vibration can loosen connections or even deteriorate the rubber over time.

The main component is the charcoal canister. While it’s not something that deteriorates with regularity, it can need replacing if you’re having emissions problems.

Every system on your vehicle works to keep your car running smoothly.

Whether you have a check engine light that won’t turn off, or are noticing your car is running rougher than before, don’t wait for bigger problems to arise.

How Much Do Today’s Cars Pollute? Reducing Pollution Through Better Car Maintenance

by

Global warming. Climate change. Energy efficiency. Green technology.

Each of these concepts stirs up a lot of debate. But no matter how you feel about each subject, chances are you’re doing something to reduce your carbon footprint and make your world a better place.

Take car pollution, for example. According to the EPA, automobiles and other light vehicles are one of the leading causes of air pollution.

Think back to cars from the 40s, 60s, or 80s. What’s the one thing that continually changes over time? Efficiency. All you need to do is follow a car from the 60s for a few miles and you’ll realize just how much progress we’ve made with car pollution.

What causes air pollution?

The main cause of car emissions is gasoline. When you start your car, it requires gasoline to operate. (Electric cars are changing this, but for now, we’re talking about gasoline operated vehicles.) As gasoline burns, pollutants such as carbon dioxide, nitrogen oxide, and other hydrocarbons escape through the tailpipe. They also escape as the gas flows throughout the vehicle, operating the various systems that make your car run.

How Much Do Today’s Cars Pollute? Reducing Pollution Through Better Car MaintenanceThese pollutants escape and cause problems as they react with the environment. When exposed to sunlight, for example, hydrocarbons impact ozone. Nitrogen will linger in the atmosphere and add to acid rain. Carbon dioxide traps heat here in the earth’s atmosphere. And all of this has been building over time – for over a century as auto production has scaled over the years.

If you want to reduce car pollution, your first steps are to clean up your car and the way you drive.

Upgrading your vehicle is a step in the right direction – every new make and model adds more efficiency to the cause. But even models several years old can be maintained for maximum efficiency.

How do you reduce emissions, and reduce car pollution to the best of your ability?

These are the parts and systems that help reduce air pollution

Today’s vehicles come with an emission control system. Chances are you need an emissions test every so often in order to license your vehicle for the road. An emissions control system is specifically designed to reduce nitrogen oxides and volatile organic compounds that impact the environment.

Your vehicle also has an onboard diagnostic monitoring system to monitor the inner-workings of your car. If it finds a problem somewhere within the engine compartment, for example, it will trigger the “check engine” light to come on. This often is a problem related to the transmission system, or to emissions feeding through your tailpipe. Acting quickly can fix the problem and eliminate costly repairs down the road. The most common auto parts that play a part in reducing car pollution include:

The air injection pump – pushes air into the exhaust manifold to allow fuel to burn more completely.

The catalytic converter – it oxidizes the volatile organic compounds and reduces nitrogen oxides.

The exhaust gas recirculation system – also known as EGR, this system returns exhaust back into the combustion chamber to aid in lowering emissions.

The misfire monitor – this turns on the check engine light whenever a misfire occurs in the engine compartment.

The oxygen sensor – monitors the best possible mix of fuel and oxygen. If this sensor isn’t working right, it can cause your car to waste more gasoline.

The positive crankcase ventilation valve – also known as PCV valve, it redirects vapor into the intake manifold. This helps prevent engine corrosion, and reduces emissions by increasing efficiency.

How to reduce car pollution and emissions

Colorado has rules in place that require your vehicle to meet certain guidelines to car emissions. Counties that require emissions tests include Boulder, Broomfield, Denver, Douglas, Jefferson, and portions of Adams, Arapahoe, Larimer, and Weld. If you are unsure, you can contact your local county office for more information.

Your vehicle will need periodic testing in order to receive your updated vehicle registration and license. If your vehicle fails the test, you’ll need to repair your vehicle in order to gain a positive reading before you’ll be allowed to renew your registration.

To keep your car in good working condition and to avoid potential emissions related problems, a good maintenance schedule will benefit both your vehicle and the environment.

Get regular tuneups

If your car is running rough, it is more likely to be releasing higher emissions into the environment. It may be a clogged filter, poor oil quality, spark plugs that aren’t firing correctly, or a timing problem that’s preventing fas efficiency. Schedule regular tuneups to ensure your car is always working at its best.

Tire pressure

While many drivers associate efficiency with the engine, your tires play a big part as well. Proper tire pressure ensures your gas mileage is as high as possible, and that your vehicle is operating correctly. Every piece in your car plays an equal part to help in achieving efficiency.

Read your owner’s manual

We all lead busy lives, and have priorities weighing on us all the time. Sometimes it can be easier to push maintenance aside and focus on things that are more pressing. That creates a cycle of responding to emergencies rather than performing preventative maintenance. It also creates a pattern of paying more for repair work than is truly needed.

If you haven’t taken the time to become familiar with your vehicle’s owner’s manual, spend some time getting to know your car. Pay attention to service markers that can impact how your car operates:

  • How often you should change brake pads
  • How often you should replace the timing belt
  • How often you should service the transmission

Of course, these are just a few of the systems your car needs serviced throughout its lifetime. By being proactive, paying attention to mileage markers, and knowing how long individual parts should last, you’ll be able to replace parts before they turn into bigger problems.
