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

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

You may have heard about an important part of your vehicle's engine called a timing belt, and many know that if that belt breaks, it can cause some very serious engine problems. Not all vehicles have them, and the ones that do generally have smaller engines. The timing belt keeps the engine synchronized so that every time a spark plug fires, the crankshaft, camshaft, pistons, and valves are all working together. Timing belts will eventually have to be replaced, and most vehicle manufacturers recommend when that should be. Typically, it's around every 60,000-100,000 miles, or 100,000-160,000 km. It's a good idea to stick to your vehicle's schedule or be alert for signs that the timing belt may be failing prematurely. Some of those symptoms? Maybe your engine won't even turn over when you try firing it up. You might hear a ticking or banging sound under the hood. Perhaps you spot an oil leak or notice the engine misfiring. If any of those are happenin ... read more

What's the dif? To an automotive technician, it's the differential, a part of your vehicle that helps direct power from the engine to the wheels. The differential is a gearbox that enables the drive wheels to turn at different speeds (they do that when you turn). Inside the differential is a fluid that makes sure those gears and other parts are lubricated since there are a lot of metal moving parts in there. (Your vehicle may have more than one differential in it depending on the drivetrain.) As you can imagine, it's important that the lubricant in those differentials do its job. Otherwise, the gears may be damaged by heat and friction. The more you drive your vehicle, the more likely it is for that lubricating fluid to break down. So, it's important to have the differential fluid exchanged every so often. Your vehicle's manufacturer recommends how often your model should have that done, but a common interval is every 30,000-60,000 miles/50,000 km ... read more

While many components of your vehicle are complex and composed of lots of mechanical and electrical parts, there's one that isn't complicated but still important. It's your engine air filter. (And, we should point out, the engine air filter isn't to be confused with the cabin air filter. The cabin air filter cleans air that goes into the passenger compartment while the engine air filter cleans air that goes into the engine itself.) Why does your engine need a filter? Think of all the stuff–dirt, dust, and debris in the air¬–that gets kicked up on the road. If that were to go unfiltered into your engine, it could damage other components. There are many different materials used in an engine air filter, including paper, cloth (frequently cotton), and other synthetic fabrics. The material is usually folded tightly to maximize the filtering capability over a relatively small surface. Before computers were employed to determine the proper mix of ... read more
