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

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

If someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent. But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should. The oxygen sensors measure how much oxygen is in your exhaust. If there's too much, it means there's a problem with the mixture of fuel and air. The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency. It does this constantly. Many vehicles have multiple oxygen sensors. Some have one close to the engine, another close to the muffler. Two measurements are better than one since they allow readings to be more accurate. You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors. Your oxygen sensors can fail. One thing that can damage them is contaminat ... read more

When you start up your gasoline engine car, you may not know that it's using the same ignition principles as it has for decades. You have spark plugs that require enough power so a spark can jump across a gap at its tip. Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval called timing. The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off. That higher voltage then was sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers. Engineers later replaced the switching mechanism with solid state ones, but they still needed replacement after 120,000 miles/200,000 kilometers. The next evolution came in the 80's when the distributor ... read more
