Even in the months where temperatures are cooler, heat is still an enemy of your vehicle. When your engine runs, it creates heat, so there are numerous heat shields that protect other parts from those higher temperatures. Heat shields are installed around several areas of the exhaust system. Others prevent heat from reaching parts of the vehicle. Still others prevent heat from reaching the ground (or maybe grass underneath) and starting a fire. If you remember your space travel history, you'll know how important a heat shield can be. John Glenn was the first American to orbit the earth, but during that maiden orbital flight, a sensor on board was indicating the heat shield on his capsule, Friendship 7, was loose. If it had come off, his spacecraft could have burned up upon re-entry. Fortunately, the heat shield stayed on, and Glenn made history. Unfortunately, the heat shields on your vehicle don't have warning systems like the space vehicles did.&nb ... read more

If there’s one thing you should pay attention to with your vehicle, it’s the temperature gauge. It’s the one that may say C---H (that means “cold---hot”). Or maybe yours has a picture of a thermometer on it and a blue and red zone. If you see the needle heading farther to the “H” or red area, that means your vehicle’s engine is running hotter than it normally does. One of the most common causes of an engine running hot is a leak in your cooling system. Maybe you’ve seen puddles of coolant under your vehicle, or you’ve smelled the coolant, either inside or outside your vehicle (it has a sort of “sweet” or fruity smell). That’s your engine giving you a warning signal that it’s time to head over to your repair facility to find out what’s going on. Your vehicle’s coolant can leak for several reasons. You may have hoses that are deteriorating (heat and age take their toll) ... read more

If someone told you there was a fairly inexpensive way to improve your vehicle's handling, fuel economy and extend the life of your tires, you'd probably ask, "What do I have to do?" The answer is to rotate your tires. But you have to do it regularly. A lot of drivers think skipping tire rotation is a way to save money. But when you don't rotate your tires, they will almost certainly wear unevenly. That's because when your tires touch the surface of the road, the friction and traction causes miniscule parts of the rubber to come off. And that process isn't exactly the same on each corner of your vehicle. Some vehicles have the drive wheels in the front, some in the rear and some on all wheels. Rotating your tires at regular intervals minimizes the differences in the way the tires wear. The amount and pattern will be spread out equally if your tires spend time at all different positions. The more even the wear, the more consistent traction, hand ... read more

You may remember a song that went, "Objects in the rearview mirror may appear closer than they are." While that was a song about life's lessons, there are a few things we should all know about how important rearview mirrors are to safe driving. While new electronic devices are helping drivers be aware of surrounding traffic in high-tech ways, the good old rearview mirror is still a dependable way of letting you know what's around you. There are usually 3 on each vehicle, 1 attached to the windshield inside and 2 attached outside on each of the front doors. It's important that they be adjusted properly before you start driving (not while you're driving). Experts say the windshield rearview mirror should cover the area behind the vehicle while the outside mirrors should not simply duplicate that view but extend it to the sides, where blind spots normally are. Your rearview mirrors must be able to hold the positions they're adjusted in; it there's play in them or they move around, y ... read more

If you've ever ridden down a rough road on your bicycle, you know how hard a ride it can be. Yet drive down the same road in your car, truck or SUV and it miraculously will smooth out the ride. That's because it is equipped with shock absorbers. They are built to dampen impacts from road irregularities. But after taking hundreds of hits from potholes, railroad tracks and curbs, your shock absorbers can wear out. Besides the rough ride that can cause, there are other ways your vehicle's performance can be affected. When it comes to braking for example, you may take a longer distance to stop. That's because shocks help keep your tires in contact with the surface of the road. If the shocks aren't working properly, the tires won't make contact like they should. So when you slam on the brakes, your vehicle will take longer to stop. Consider what worn out shocks are doing to your tires. Since the bumps aren't being dampened as much, your ... read more

You may have noticed sometimes on a hot and humid day, vapor will come out of your vehicle's vents when you have the air conditioning on. Is that something to be concerned about? Well, it depends. Sometimes that steam or vapor can be caused by water accumulating in the vent system after it has condensed. And sometimes water can pool at the bottom of a vent. When you turn on the blower mower, the air hits the water and may create steam or vapor that you can see in the cabin. One thing to check is if that vapor smells like anything. If it doesn't, that's a good sign. You may be able to run the fan for a while and the issue may just go away when things dry out. But moisture collecting in the ventilation hoses in a hot vehicle may be a breeding ground for mold, and that can have health consequences. There's another possibility. Ventilation systems often have drains to get rid of any accumulated water, and debris can sometimes clog them. A technician can ... read more

Vehicle emission testing has become ubiquitous in North America and for a good reason. Clean air quality is important for the environment and all of us. Since vehicle emissions are among the main causes of air pollution, emission testing can alert you to problems in your vehicle than can be fixed so it won't needlessly pollute. Emissions tests are looking for certain toxic gases internal combustion engines produce, such as nitrogen oxide, particulate matter, non-methane organic gases and formaldehyde. Emissions control systems reduce these gases if they are working properly. The best way to minimize pollution is to keep those vehicle systems working properly, and periodic inspection and maintenance is the key. So if you want to make sure your vehicle will pass an emissions test, it helps to know what might go wrong. Let's start on the easy one. Your gas cap could be loose, allowing vapors to escape into the atmosphere. The most common solution ... read more

We all have joints in our own skeletal system, but did you know your vehicle has some joints of its own? One of the most important is called a ball joint. One of the interesting things is that it's somewhat similar to the ball and socket joints we have in our hips and shoulders. A ball joint allows two parts it joins together to move in more than one direction at the same time. Think about your wheels. They have to move up and down when there are bumps in the road but in sideways directions when you are making a turn. As you can see, the ball joints are important for your steering and handling to work correctly. Since ball joints do so much, they can wear out and become loose. When the ball wears down or the socket gets worn, there can be too much play in them. It can get so bad that the ball can come out of the socket and your wheel can fall off, a dangerous situation. Ball joints can also seize up. Some of them are sealed and never require maintena ... read more

Some drivers don't pay any attention to their vehicles until something breaks. Others take them into their service repair facility for maintenance even before a problem develops. Still, even if you fit into the second group, there are some parts on a vehicle that will simply wear out over time. Your vehicle has gaskets in several places. They use a flexible material to seal the gaps between metal parts that fit together. After time, that material shrinks or gets brittle and fails. Eventually, after time, you will have to get gaskets replaced. Same goes for belts. Your engine has belts that help take the mechanical energy of the engine to drive other parts such as the generator and air conditioner. Heat and age will eventually cause these belts to wear out or break, so you'll need new ones at some point. You'll also find yourself buying brake pads. As much as you may try to go easy on them, brake pads work by wearing off a little bit of them eac ... read more

Automotive design has come a long way since the days of the Model T, especially when it comes to safety technology. You can thank computers for a lot of the latest innovations. Here are a few that have been making their mark in recent years. Adaptive cruise control. This is cruise control with a brain. Not only will adaptive cruise control keep your vehicle going at a steady speed, it will also slow it down and even stop it if the vehicle ahead of you slows down and stops. Automatic emergency braking. We've all been distracted while driving, and you've probably been in a situation where the driver ahead of you has suddenly stopped. Or maybe your attention wandered for a minute and you looked up to see your vehicle closing in fast on the car ahead of you. (After all, there are a lot more distractions in your vehicle these days.) New systems that use cameras, lasers and other types of sensors will warn you to start braking. If y ... read more
