How Your Car Is Like Your Body

If you have a fever, you don’t feel well, right? Well, in order to function properly, your vehicle’s engine needs to run at the right temperature, too. So if your engine is running too hot, a sensor goes off and coolant is released to cool the engine off.

The Waze Craze: Part I

What would we do without GPS? I suppose we would go back to writing down directions and getting lost, but why? With GPS, life is much easier, allowing us to hit the open road without fear and encouraging the wanderlust that lies at the core of all Americans.

Are You a Man in Need of a Van? Try the Dodge Caravan R/T

When my best buddy, David, moved his family into a new place in Orange County, CA, he was curiously excited about giving me a tour. When I finally made it down there, we took about thirty seconds to check out the three-bedroom townhouse before he beckoned me out the back door.

Brakes

All drivers know that to stop a vehicle, you press the brake pedal. But how does the pedal make the vehicle stop? Brake systems slow and stop the vehicle by applying pressure to rotating brake discs and/or brake drums, which are attached to each wheel.

Drivetrain

The engine is what powers your vehicle, but how does it transfer that power to the wheels and get you moving down the road? Through the drivetrain. Simply put, the drivetrain—through a series of parts—connects the engine to the wheels.

Electrical and Lights

When you switch on the ignition, turn on the radio, operate the windshield wipers, and crank up those seat warmers, your vehicle's electrical system is what provides the power. While the battery is what initially starts the vehicle (and serves as a backup power supply), during vehicle operation, the electrical system is powered by the alternator.

Engine

The engine is a mechanical device designed to convert chemical energy (fuel) into kinetic energy (motion), which powers your vehicle. Almost all vehicles (including hybrids) use internal combustion engines that burn fuel.

Exhaust and Emissions

During normal engine operation, exhaust gases are created. When this exhaust leaves the engine, it is loud and contains gases and particulates than can be harmful to humans and can contribute to poor air quality.
