Heat isn't easy on vehicle tires, and as the seasons change, make sure yours are ready to take the heat. Let's talk first about inflation. Heat causes air to expand, so heat alone can raise the pressure in your tires. If you are driving on overinflated tires, they won't have as much contact with the road surface. In that case, it will take you a longer distance to stop. On the other hand, you don't want your tires to be underinflated during hot weather, either. That can cause your sidewalls to flex. Friction will then hike up the temperature and your tire can be in danger of blowing from the added heat. Other things can cause problems, such as uneven wearing. Your service advisor knows the signs to look for and can diagnose where the wear is and what is likely causing it. Another thing a technician will look for on tires is tread depth and the condition of the sidewalls. Any cuts, cracks or bulges could be indications that your tire ... 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

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself. There was a time when vehicles were simpler and it wasn't too hard for a weekend mechanic to replace brakes, adjust a carburetor or perform a tune-up. But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, air bags and fuel injection just a small sample of the new technologies. Like a lot of things these days, technology changes in leaps and bounds. Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more. Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems. Computers are an integral part of much of the latest automotive technology, something you didn't see a lot of until as recently as the 1990s. Today's most hig ... read more

Who thinks about their fuel gauge? You probably don't… until it doesn't work any more. Then you have to guess how much fuel is in your tank, and that's no way to live life on the road. Fuel gauges, like every other part in your vehicle, can fail. And when yours stops working, you will probably want to head over to your service facility soon, because no one relishes running out of fuel. The fuel gauge system is much more than just the gauge you can see on your instrument panel. Most systems have a float inside the fuel tank that goes up and down depending on the fuel level. It's called the fuel sending unit, and it sends an electrical signal to the gauge (on the dash) telling it to display how much fuel is left in the tank. So, what could go wrong? Well, a few things. For one thing, corrosion from bad fuel can cause it to stick and it won't move up and down any more. So you could fill up your tank and the gauge would still rea ... read more

Colder weather brings out the worst in a vehicle's battery. On a very cold day, you may have experienced that your engine cranks slowly when starting. But while it may be the battery itself, it may also be the parts that transfer the power to other the other electrical components, the battery cables. After all, you have to have some way to get the current out of the battery and out to where it needs to go. Battery cables have a couple of enemies: corrosion and age. You may have looked under the hood and noticed a light-colored powder or crust around the terminals. That's what happens when acids corrode the ends of the battery terminals. Corrosion inhibits the connection and may reduce the amount of power getting to the electrical accessories to the point where they are not working correctly, if at all. Here are some symptoms of problems with your battery cables. You might notice a clicking sound when you turn the key, some of your vehicle's electrica ... read more

There's nothing like that sinking feeling when you turn the key and nothing happens in your vehicle. A lot of us are quick to blame the battery. But it may instead be your alternator that's failing. Your battery supplies power to start your vehicle, but the alternator is what sends power when your engine is running. The good news is alternators last a fairly long time, and it's not unusual to get seven years out of one. But they can give up the ghost thanks to the harsh conditions in the engine compartment. Alternators have bearings inside them that keep things turning smoothly. Debris, liquid, dirt and more can team up with the high temperatures your engine generates to cause those bearings to seize up. That's not good, and if that happens, you may even be able to hear the bearings grind. Other symptoms of a dying alternator are a squealing noise in the engine compartment or your headlights may go dim and bright, dim and bright. You might even notic ... read more

Driving along, your exhaust system's rumbling so loud that people turn and stare at you pass by. You're wondering when the police are going to pull you over for illegal noise. Your mind immediately thinks, aha! A broken muffler. Well, your exhaust system is composed of many more parts than just a muffler. Your engine makes power because of thousands of tiny explosions from detonating fuel. Those explosions make a racket, so engineers came up with a system that acoustically dampens that sound in addition to getting rid of harmful exhaust. In the engine is the exhaust manifold that looks like several pipes that join up into one pipe. It directs exhaust to the catalytic converter. The catalytic converter converts harmful gases into less harmful gases using certain chemical reactions. Then comes the muffler that has baffles inside to quiet the sounds of your engine noise. Finally: the tailpipe. All of those pipes and parts are joined together by cl ... read more

Your vehicle is like you in a way. When it gets hot, it needs to be cooled down. And one of the key parts to keeping it cool is the water pump. Now, that's a bit of a misnomer. It IS a pump, but it's pumping coolant, not pure water. Cooling off your engine is vital since it builds up heat when it creates power by burning fuel. Your water pump acts as a way to recirculate that coolant. It goes through a series of tubes and hoses through the engine where it picks up heat, then is sent off to the radiator to get rid of that heat. Cooled off, the coolant is recycled through the water pump to start the journey again. The water pump works by taking mechanical power from the engine, usually from a belt. Obviously, that belt has to be in good condition and adjusted properly or else the water pump won't be able to do its job. Here are some things to look for that will signal problems with your water pump. If your heat gauge is erratic or sho ... 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

Most of us look forward to spring because the days are longer, the weather's warmer and we can finally get our vehicles into warm weather mode. Here are a few things that will breathe fresh energy into anyone's car, SUV, truck or van. First thing is a good cleaning, especially underneath. If you live where salt and brine are used on the roads, it's important to get that off. One thing to note… if you hose off your undercarriage, be careful not to get your spark plugs/wires wet. You could notice your vehicle running rough plus the Check Engine light may come on. It usually dries out quickly, but if the engine light stays on for more than a couple of days, have your service facility check it out. Next, replace your windshield wipers. They've taken a beating through the winter. New ones will have fresh rubber and you'll see clearly (and safely) out your windshield again. Have your brakes inspected. That salt doesn't do your brake's metal components any ... read more
