If you have an internal combustion vehicle, you know it has a lot of hoses that carry various fluids. And if you have a heater in your vehicle, you'll have heater hoses. A heater hose connects to and from the engine so some coolant can be circulated through a little radiator called a heater core. In cold weather, that heater core acts as a heat exchanger to heat up your cabin. Even in the hot weather, the heater hoses can prove problematic. That's because they may remain pressurized even though you're not running your heater. Heater hoses are made out of tough materials since they must handle heat and pressure. But even the durable rubber, plastic and metal they are made out of can crack or leak from years of use. That means coolant can be sprayed out into the engine compartment or leak onto a driveway or garage floor. You may be able to see a puddle of coolant under your vehicle or perhaps smell the odor of the coolant under the hood. So ... 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

When it comes to your vehicle, driving it too much can cause some issues. But what about not driving a vehicle enough? That has consequences as well. Here are a few things that can happen if a vehicle isn't driven enough. When the engine doesn't operate, the oil isn't lubricating. That means some mechanisms that need periodic lubrication aren't getting it. And oil that sits around breaks down over time. In fact, some experts say you should change oil more often if your vehicle sits in the driveway than if you drive it regularly. You've heard that expression, "Take it on the highway and blow out the engine.” Well, carbon buildup used to be a problem in older vehicles. But the real culprit these days is moisture that builds up from combustion if your vehicle never gets hot enough to burn it off. That water vapor can mix with oil and cause sludge to form. There are many vehicle systems (battery, exhaust system, engine seals, etc.) that benefit fro ... 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

We all have joints in our own skeletal system, but did you know your vehicle has some joints of its own? One of the most important is called a ball joint. One of the interesting things is that it's somewhat similar to the ball and socket joints we have in our hips and shoulders. A ball joint allows two parts it joins together to move in more than one direction at the same time. Think about your wheels. They have to move up and down when there are bumps in the road but in sideways directions when you are making a turn. As you can see, the ball joints are important for your steering and handling to work correctly. Since ball joints do so much, they can wear out and become loose. When the ball wears down or the socket gets worn, there can be too much play in them. It can get so bad that the ball can come out of the socket and your wheel can fall off, a dangerous situation. Ball joints can also seize up. Some of them are sealed and never require maintena ... read more

If someone told you there was a fairly inexpensive way to improve your vehicle's handling, fuel economy and extend the life of your tires, you'd probably ask, "What do I have to do?" The answer is to rotate your tires. But you have to do it regularly. A lot of drivers think skipping tire rotation is a way to save money. But when you don't rotate your tires, they will almost certainly wear unevenly. That's because when your tires touch the surface of the road, the friction and traction causes miniscule parts of the rubber to come off. And that process isn't exactly the same on each corner of your vehicle. Some vehicles have the drive wheels in the front, some in the rear and some on all wheels. Rotating your tires at regular intervals minimizes the differences in the way the tires wear. The amount and pattern will be spread out equally if your tires spend time at all different positions. The more even the wear, the more consistent traction, hand ... read more
