If you were to name the most important safety feature on your vehicle right now, what would your answer be? A lot of driving experts would agree that it’s your brakes.  Most newer vehicles use a well-engineered and efficient style of brakes called disc brakes.  The name disc brakes comes from one of the components: a disc attached to the wheel hub that is squeezed by parts called calipers.  If you’ve ever ridden a bicycle with hand brakes, you probably have seen how they squeeze against the rim of the bike wheel to stop the bike. It’s similar to the way your vehicle’s calipers squeeze against the disc rotor, with added parts called brake pads attached to the calipers that are what create the friction and stop your vehicle. Here’s why disc brakes need regular maintenance.  Over time, that friction creates wear and tear on the brake pads and the rotors, and you’ll start to see the signs.  Your brakes may have one of the 3 &ldqu ... read more

Winter and freezing temperatures present challenges for different parts of your vehicles.  For example, winter tires give you better traction on snow.  But some parts of your vehicle that may need special attention for winter are your windshield wipers. You may have found yourself in the middle of a snowstorm when your windshield wipers are doing nothing but streaking slush that ices up on contact on the glass.  Now you're more blind than you were before! Obviously being able to see during a snowy or icy winter event is important for the safe operation of any vehicle.  So keeping your windshield and rear window clean can go a long way to guarantee you can see your surroundings. Let's start with the wipers.  Blades that are good for hot weather may not be robust enough for freezing weather. You can buy special winter wiper blades that stay flexible during sub-zero temperatures.  The stiffer frames that hold them have a rubber covering that prevents ice and ... read more

You expect your heater/air conditioner to work like it should.  You have a control for temperature and one for fan speed.  You even have a control for what vents the air comes out of.  Don't be surprised one day if your blower fan develops a mind of its own and starts going crazy.  Most of the time, you may find that it starts blowing at full speed, and nothing you do to try to control it does any good.  This is what may be happening. Your blower motor has an electronic component called a resistor.  It does what its name says; it offers resistance.  When you want the fan to run more slowly, you turn the fan speed down.  That resistor accomplishes that by turning its resistance up.  When the resistor fails, the power has nothing to slow it and the fan speeds up.  It's a small part and can fail due to age or corrosion.  It's usually not an expensive part, either, but it's often found in a location that's not that easy for the technic ... read more

"I never expected it could happen to me." Countless drivers have said that after they've had an emergency turn their lives upside down. So before that happens to you, let's thinking about planning ahead for an emergency with a few things you should keep in your vehicle. Road flares. If you've ever driven by a disabled vehicle sitting at the side of the highway at night, you know how terribly hard it is to see, especially in bad weather like rain.  If you are the one in that broken down vehicle, you run the risk of being hit by a vehicle whose driver literally may not be able to see you.  The best emergency signal includes one or more road flares.  There's a reason police officers and firefighters carry them in their vehicles.  When you see a series of burning red flares at the side of the road, you know something serious is going on.  These are far more visible at a much longer distance than nearly any other portable signal device.   Fire extinguisher ... read more

OK, so you probably take your vehicle's battery for granted.  Turn the key or push a button and it starts right up.  During times of warmer weather, you probably think your battery can take it easy.  But it may surprise you to learn that hot weather can be much harder on a vehicle's battery than cold.  So it's wise to know what condition your battery is in BEFORE you find out the hard way—being stranded by a dead battery. Your vehicle's battery won't last forever; an average battery will last 3-5 years.  When's the last time yours was replaced? You probably have no idea.  Your vehicle will usually give you some hints that it's in need of attention.  See if any of these are familiar: your engine doesn't turn over as quickly as it used to your headlights are a little dimmer your Check Engine or Battery dashboard light is on you hear a click when you try to start your vehicle some electrical equipment in your vehicle isn't behaving the way it used ... read more

When you head to the doctor, you probably have it in your mind what you're going to say about why you don't feel good.  That way your doctor can use that information to diagnose your problem. You might want to think of that same approach when you take your vehicle in for a repair. Experts say what will help the service advisor most is for you to bring in some well-organized descriptions about your vehicle's issues.  You might even want to write them down so you don't forget.  Is there an unusual smell?  What does it smell like?  Does the problem happen first thing after starting out? If there's an odd sound you hear, is it dependent on speed?  Does it change when you turn a corner?   Keep your expectations realistic.  Some conditions may take a long time to diagnose and repair.  If you go thinking you'll be in and out in no time, you might be disappointed when you're told there are other customers ahead of you and you may have to come b ... read more

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

No one likes to be greeted in the morning by having someone screech at you.  The same goes for a loud, high-pitched noise your vehicle greets you with every time you start the engine.  If you're wondering if that's normal, no, it isn't.  And it is worth getting checked out.  The good news is that it might be nothing serious.  Then again, it may be. The first things to suspect any time you hear a high-pitched sound coming from the engine are belts.  They have tension on them and they're trying to turn lots of different pulleys, pumps and other equipment the engine needs to work properly.  The noise could come from the belts starting to wear out and dry out. If one of those belts breaks at an inopportune time, not only can it strand you somewhere, the damage to the engine could be very expensive to fix. Other things that will cause a high-pitched sound are the pulleys and tensioners.  The tensioners keep the right amount of pressure on the belts an ... 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

You probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool. First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond. Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient tem ... read more
