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

If your vehicle’s power goes to the rear wheels, then you have something called U-joints in the drivetrain. U-joints are connectors that allow the rotating power from your vehicle’s engine to deliver its power through a driveshaft to make the rear wheels rotate. You need U-joints because the surfaces you drive on aren’t perfectly flat, and the driveshaft has to allow for some flexibility when you are traveling over uneven surfaces. As you can imagine, the U-joints have to move and flex a lot as your vehicle is going down the road. They have bearings in them to allow that flexibility, and those bearings are lubricated when your vehicle is made. Some U-joints have lifetime lubrication and are not designed to be serviced. When they fail, they have to be replaced. Others have grease fittings on them that need periodic lubricating by a technician at intervals recommended by your vehicle’s manufacturer. There are signs you can look ... read more

It's safe to say that most drivers take their brakes for granted. You press on the brake pedal and the vehicle slows down or stops. It's easy to see why it is so important for your vehicle's brakes to be working correctly. Brakes are an important safety feature of any vehicle. When it comes to your brakes working correctly, maintaining them regularly will ensure that you will always be able to slow or stop your vehicle in any situation, whether on a sunny day on dry pavement or a bad weather day on slippery surfaces. And that is why regular brake service is such a sound investment for all drivers. The combo of brakes" and "surprises" doesn't usually end well. You might already know about some of the parts of your braking system. Terms familiar to you might be pads, rotors, and calipers. In short, the calipers press the pads, which in turn contact the rotors. The resulting friction slows your vehicle. Another type of brake uses a drum and brake ... read more

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

Tires are so reliable these days that few drivers pay much attention to them. But tires wear out. They have a tough job since they are the only point of contact between your vehicle and the road. They have to get your vehicle going from a stop, keep it going, make sure it is headed in the direction you want it to go, and –importantly – slow and stop it. The only time many drivers think about their tires is when there's a problem, such as a flat. Or, they may lose control when they find their vehicle isn't stopping or steering like it used to. One major safety organization estimates that 1 out of every 11 crashes is related to a tire issue. Many of those problems are caused by tire tread wearing out. The rubber is worn off by friction after hours and hours on roads. The sidewalls can also be damaged by your tires hitting curbs, potholes, or other debris. Plus, rubber ages as time passes. We recommend you let us in ... 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

You’ve probably already heard that regular oil changes are extremely important for the health of your vehicle’s engine. That’s sound advice. But what you might not know is when it comes to motor oil, the real thing may not be the best thing for your engine. There are different types of motor oil:
• Conventional oil, extracted from the ground and refined.
• Synthetic oil, manufactured from high-quality base oils and artificially-made chemical compounds.
• Synthetic oil blend, a mixture of conventional and synthetic oils. The first thing you need to know is that most new engines require synthetic oil. If synthetic oil is recommended for your car – you MUST use it. For the rest, there are many advantages to using synthetic oil over conventional oil. • Synthetic oil provides better protection for your engine while helping it to perform better.
• Co ... read more

Your vehicle’s engine runs hot. It should, since it’s a series of little explosions that create the power that gets you going where you want to go. To keep the engine cool, engineers have designed wonderful cooling systems that use liquid coolant, hoses, and a radiator to transfer the heat from the engine to the outside air. In order for the system to work right, it has to have the right amount of that liquid coolant in it. So that you know when the coolant has dipped below the correct amount, there is a sensor that keeps an eye on it. When the coolant gets low, that sensor lights up a signal on the dash to alert you. It may literally say “Check Coolant” or it may have a picture that looks like an old-style bulb thermometer sitting in liquid. Your owner’s manual will usually tell you exactly what the one in your vehicle looks like. If that sensor system isn’t working right, you could wind up driving for a lo ... 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
