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

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

Most drivers love how easy it is to turn their vehicles, and they have power steering to thank. Engineers have figured out a way to take some of your engine's power to help you turn. Without it, steering can be quite a chore. New power systems are electric, but there are still plenty of the older hydraulic power steering systems out there, and it's wise to keep them working the way they should so you don't find yourself stranded without power steering. Those hydraulic power systems use a fluid under pressure that is pumped to a device that helps you turn your wheels more easily. It's that pressure that presents the challenge. After your vehicle's seen a few years on the road, you may find your steering isn't quite as easy as it was. You may hear a groaning or humming sound when you turn. One component that can fail is the pressure hose that carries that fluid from the power steering pump to that turning assist mechanism. The hose is made of rub ... read more

You've probably never paid much attention to the writing on the sides of your tires, but they contain a wealth of information. There's a long combination of letters and numbers that can tell you a whole lot about what tires your vehicle was designed to be riding on. Let's check out this example found on an SUV: P245/70R17 108T. The first letter, P, means it's intended for passenger vehicles. If there's no letter, it means it's a metric tire. If there's an LT at the beginning or end that means a tire designed for light trucks. Moving on to our example, the 245 shows how wide the tire is in millimeters from sidewall to sidewall. The number that follows in our example, 70, means the height of the tire is 70% of its width. The letter after that in our example, R, describes the type of tire (on this vehicle, radial). Following that is the diameter in inches, in our SUV example, 17 inches. How much load the tires' sidewalls are designed to take ... 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

It's bad enough when you mistakenly leave a window open in your vehicle on a rainy day and you find your carpet soaked. But what in the world is going on when your windows are closed tight, not leaking and you STILL wind up with wet carpet? The answer could be something you might not even know your vehicle has. And the answer is? Drains. And those drains can get clogged. Yes, your vehicle has several drains with tubes or hoses attached to them that you really never see. There are some in and around the hood that channel rainwater down to the ground. There are some that take condensation from the air conditioner and allow it to flow outside. And if your vehicle has a retractable sunroof or moon roof, there are small drains at each corner that connect to tubes that go through the vehicle body down to an exit near the ground. Considering all the leaves, dirt, dust and other debris your vehicle encounters on a daily basis, it's not surprising that these ... read more

If you hit a bump in the road and your vehicle just keeps bouncing up and down for a lot longer time than it used to, you may have bad struts and shocks. They're the things that help to keep your vehicle's wheels and tires planted to the road surface. But they don't last forever. With care and depending on where and how you drive, shocks and struts should be replaced at intervals ranging from 50,000 miles/80,000 km to 100,000 miles/160,000 km. If you drive on bumpy roads with a lot of potholes, that interval will likely be shorter. Rough surfaces can take their toll. But how do you know if your shocks and struts are doing their job properly? The best way is to have your vehicle checked by a technician. He or she can inspect the shock absorbers and struts for leaks, corrosion and damage. Mounts and bushings can also go bad and they should be evaluated as well. A thorough examination by a technician will also include looking at other suspension parts ... read more

Whether we're trying to save money, save gas or save the environment, most of us TRUCKEE drivers have an interest in decreasing fuel consumption. We've all heard about ways to save money on gas in CA, but does it really add up to much? How much can we boost our fuel economy through preventive maintenance and more courteous driving?The US government has a website that actually answers that question. Let's look at some of the data and find out if any of these fuel-saving ideas are really worth the effort. We've all heard that a tune-up can improve gas mileage. It turns out that it can save us 4% at the pump. At $3.50 a gallon, that's 14¢ per gallon in savings, and at $4.00 a gallon, that's a 16¢ per gallon savings.Other common repair items can also save you at the pump. For example, if your oxygen sensor is faulty, it's not delivering the information to your engine's computer that allows it to calculate the right fuel-to-air ratio. The result? The fue ... read more

Whether or not your exterior light bulbs are all working probably is not at the top of your list when you think about your vehicle. But those exterior lights are more important than you think, and they're vital to your safety and that of other drivers near you. Headlights are important. Not only do they help you see safely down the road at night, they also help oncoming drivers know that the vehicle they're approaching is not a motorcycle. Both headlights should be working properly and aimed so that they don't blind other drivers. Taillights are also important for a few reasons. They tell drivers what your intentions are (changing lanes, turning, stopping). So, the bulbs back there must be all in working order for maximum safety. Ditto for the front turn signal lights. They alert oncoming drivers to your lane changes or turns (if you use your turn signals!). Some side mirrors also have turn signal bulbs in them. There are a few other important ... read more

We've all been through it. The vehicle ahead of us kicks up mud, slush, snow or salt on our windshield and we can't see a thing. And not being able to see a thing when we're driving? Not a good thing. Debris on a vehicle's glass can be blinding when driving directly into the sun. And other things can ruin visibility: scratches on the glass, fogged windows, mineral deposits. So lets make one thing clear: Your windows. Here are some tips. Number one rule, don't use abrasives on glass. That means no gritty cleaners that are made for metal. Avoid at all costs those dark green abrasive pads on some kitchen sponges that are made to clean metal pots and pans UNLESS the manufacturer specifically says they can be used on glass. Use the appropriate cleaner for the substance that's being cleaned off. Special automotive glass cleaners are available, and your The Auto & Tire Doctor Inc service advisor can make recommendations. Vinegar can work wonders. Som ... read more
