Ever wonder how your vehicle’s engine is able to take the 12-volts from its battery and ramp that up to as high as the tens of thousands of volts it takes to fire its spark plugs? The secret is something called an ignition coil. Most newer vehicles have an ignition coil at each cylinder, but older ones have a coil that serves all of the spark plugs. There are telltale signs that you have an ignition coil problem. As you might expect, one symptom is it’s hard to start your engine or it won’t start at all. If your engine is misfiring or not running smoothly or you see the Check Engine light come on, those all could point to an ignition coil failure. Several things can contribute to ignition coil trouble in addition to normal wear and tear. Moisture and dirt may have gotten inside the coil, plus the heat and vibration of your engine over time can contribute to them going bad. Bad spark plugs or plug wires can also be a cause.

We've all heard that expression, "That's a non starter." When it comes to your vehicle, that's not music to a driver's ears. That sickening sound when you start the ignition and instead of hearing the engine crank, you hear it slowly turn over and your dash lights go dim. There can be many reasons a vehicle won't start, so here's a little history of how the starter came to be an important component of modern vehicles. You have to move the engine's components to start it. The first cars had a crank that the driver would insert into the front, then start turning things over by hand. When the engine started, you had to release that crank immediately or risk a broken arm. Yes, it happened many times. So, they came up with a better idea: an electric starter, which was a big advance in automotive technology. With this system, an electric motor rotated a series of gears that turned the gasoline engine's crankshaft so its pistons and parts moved and the engine drew in a ... read more

Ever wonder how your vehicle’s transmission is connected to your wheels? After all, when you hit a pothole or some other uneven part of a road’s surface, there has to be something that can maintain the connection between the transmission and the wheel yet keep everything moving at the same speed. That very cool device is called a CV joint, a kind of driveshaft running to each wheel. The CV stands for constant velocity because it keeps the drive wheels moving at a constant speed (velocity). They’re used mostly on front-wheel drive vehicles but also in rear-wheel and all-wheel drive vehicles. The joints move up and down and adjust to bumpy surfaces. Plus, they are covered in a rubber boot which protects them from road debris and also holds lubrication in. There’s a CV joint and boot on the transmission side and one on the wheel side. Unfortunately, the spot that usually fails first is that rubber protective cover (the boot).&nbs ... 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
