The internal combustion engine is comprised of many small moving parts. Some of these parts rub together and create friction. With all this activity going on, an excessive amount of heat is generated inside the engine. Because of this, the engine needs a lubricant to ensure these components are cooled down and running smoothly. Engine … Read more
Most people have heard of automatic transmission and manual transmission vehicles before. But have you ever heard of semi-automatic transmissions? This type of transmission has been around since the 1930s, so it’s actually existed for a long time.

The supplemental restraint system (SRS), commonly known as the airbag system, is arguably the most important safety component in modern vehicles. It works alongside seatbelts to protect occupants during collisions. When sensors detect a significant impact, airbags deploy in milliseconds, creating a cushion between passengers and hard surfaces. After inflation, they quickly deflate to allow … Read more
Every vehicle with an internal combustion engine contains an exhaust gas recirculation system, also known as an EGR system. The purpose of this system is to reduce the level of nitrogen oxide emissions which get produced during the combustion process of a gasoline engine or diesel engine. Basically, when exhaust gas comes out of the … Read more
When a mechanic goes to diagnose a serious problem with your vehicle, they will usually hook up a scanning tool to the power control module. The computer of the module will then provide the scanner with a troubleshooting code which signifies the problem of the vehicle. For instance, the diagnostic trouble code “P0700” signifies that … Read more
Ever wonder how the electronics in your steering wheel maintain their connection when you can turn the steering wheel several times in each direction? If normal wires were run to the steering wheel controls, they would eventually get tangled up and break, just from everyday use. This is exactly what a clock spring is designed … Read more
A seat belt pretensioner is a critical component in the seat belt assembly. If you get into an accident in any modern car, its seat belt system will keep you secure in your seat so that you don’t get jerked forward or fly out of the windshield. Of course, this can only happen if you are … Read more
