You go out to your car, start it up, pull out of your parking space and see a puddle of...something...where you were parked a moment ago. This is never a good feeling. What could it be?    Fortunately, some automotive fluids are dyed different colors to make this a little easier to narrow down.    Does it appear to be water? Were you recently running your A/C? Chances are that's just condensation from the A/C system, which drips out through a rubber tube and is perfectly normal. No worries ther...

Believe it or not, the A/C system in your vehicle is fairly simple in principle and design. Like your refrigerator, it operates on a cycle of compression and expansion of a gas, known as refrigerant. The compressor turns the gas into a liquid, and as the gas evaporates it provides cooling. Like your refrigerator, its main components are:    Compressor Condenser  Receiver/dryer Thermostatic expansion valve Evaporator Refrigerant Blower  The good news is most automotive A/C systems...

At one time, there were only a couple of choices for motor oil. Today, that is no longer the case, and hasn't been for quite some time. Here's a quick breakdown of what you need to consider when it's time for an oil change: Viscosity: Viscosity is how thick your oil is, and how it retains its pour properties at various temperatures. In this respect, synthetic oil is far superior. Conventional oils will thicken in cold weather and thin out when very hot, while the viscosity of synthetic is muc...

If you’re old enough, you probably remember the cars from the late 70s and early 80s that weren’t good for much more than 120,000 miles before they started to develop real problems and were junkyard bound. Today, thanks to improvements in design, metallurgy, manufacturing techniques and machining, those days are over and it’s not at all unusual to see vehicles with well over 200,000 miles on the odometer and still running strong. Here’s a quick rundown of some vehicles to consider which hav...

Often, drivers are mystified by how their cars actually work. It’s to be expected. Even an older car is a complex machine with many sub-assemblies that all work together to move it down the road. As a result, drivers tend to be a little intimidated by auto repair and often tend to not inform themselves by asking the necessary questions of a tech or a garage. Too often, that ends up being a big mistake. Here are some examples of the kinds of things you really should know before any auto repair ...

Differential Service – Why Is It Important?    Of all the various things on a vehicle that need regular service and maintenance, the differential is too often neglected. But what exactly is it, and what does it do?    Visualize a rear-wheel-drive vehicle making a right-hand turn. As the car turns to the right, the left rear wheel will have to actually cover a longer distance and spin at a different speed than the right wheel. If the rear axle was delivering the same torque to both wheels, the...

Some people love winter. They love the snow, the snap in the air, the short days and cozy nights at home. Others can’t stand it, for many of the same reasons.
