We all want to breathe clean air and keep our planet green. One of the ways to do that is by requiring all vehicles with internal combustion engines to pass an emissions test. That’s because these vehicles can be big polluters. Everyone wants their car to pass the test so they can continue their day-to-day driving routine. But then comes that one day when they tell you your vehicle has failed. Why does that happen? One of the most common reasons is that your gas cap is leaking or loose (or maybe you don’t even have one on your vehicle!). The gas cap is supposed to seal in vapors, but sometimes its seals or gaskets dry out or crack. Replace it, and you’re good to go. Another common reason your vehicle failed the test is that your catalytic converter isn’t doing its job. It is supposed to convert toxic gases from your engine into ones that don’t pollute the air. There are many reasons the catalytic converter may not ... read more

There’s an important part in your vehicle that shields your timing belt, timing chain or cam belt from the debris and gunk that can be kicked up from the road. It’s called the timing cover. It’s important because the timing belt or chain is what coordinates parts of your engine called the camshafts and crankshaft. When they’re in sync, all runs smoothly. When they’re not, it can cause some serious engine problems. If your vehicle has a timing belt, without the protection of the timing cover, that belt can come loose from the timing gears or break. If your vehicle has a timing chain, the cover keeps engine oil circulating around it which lubricates it. When that starts to leak because of a bad gasket, the chain may not be getting adequate lubrication. If your vehicle has a timing cover problem, you may notice engine oil leaking if a gasket is not sealing tightly. You may hear a strange metallic sound coming f ... read more

Few of us ever drive somewhere without encountering some pretty rough roads, and it's amazing how well our vehicles are able to smooth out the ride. Thank your shocks and struts. The two parts are similar. Some cars have shocks in the rear, and struts in the front. Others have struts all around. A shock absorber uses a cylinder filled with gas or liquid that's connected to your vehicle's frame and axle. When your vehicle encounters an imperfection in the road, the shock dampens the motion. A strut is essentially a shock absorber mounted inside a spring and can support more weight than a shock by itself. Shocks and struts take a lot of punishment and wear out. When they do, your tires are not contacting the road as much as they should, and that can result in a bumpy, unstable ride. Worn-out shocks and struts also transfer the impacts of road imperfections directly to your vehicle's body which can cause further damage to other parts. You can tell when ... read more

Steering a vehicle these days doesn't take much effort, but if you got behind the wheel back before power steering was invented, you'd need to practically have the strength of Hercules to turn the wheel. The first power steering systems widely available changed everything. Chrysler introduced its Hydraguide power system in 1951. The "hydra" was for a hydraulic pump. It pressurized fluid that multiplied the force applied to the steering wheel so it was easier to turn the wheels on the ground. That pump got power from a belt attached to the engine, but unfortunately it wasted a lot of energy in the process. Plus, the system of hoses and pumps required a fair amount of maintenance and repair. Some say this system provides the most "natural" steering experience of power systems. Recently, automakers have turned to electric power steering. It gets its power from the car's electrical battery and charging system and uses an electric motor to turn the wheels. Sin ... read more

You climb inside your vehicle, start the ignition, and reach for the fan control for the heating or air conditioning. But when you try to crank it up, no air comes out of the vents. It can make for a very uncomfortable trip, whether it’s hot or cold outside. It’s important for the comfort of you and your passengers to regulate the temperature in your vehicle’s cabin. Not having air coming through the vents can also be a safety issue when you’re trying to defrost the windshield and front windows when they fog up and your visibility is affected. There can be many reasons why the air isn’t blowing through your vents. The blower motor may have failed or the switch that controls it wore out. It could be as simple as a blown fuse, or perhaps an electrical component that regulates the fan speed may have stopped working. One of the ducts that direct the air from the outside to the cabin may have broken. Or the air intake where ... read more
