GM Engine Parts

Your factory GM engine is made of a number of parts, all of which work together to create the power your car, pickup, or SUV needs. They also help move other parts that are essential to your vehicle's operation.

Meet Your Engine Parts

The engine block is the center of it all. Other parts connect to it, and the combustion you need occurs inside. Your engine pistons pump to compress and pressurize the mix of air and fuel inside the block. A cylinder head rides atop the engine block. This seals the engine and keeps the gases contained inside. Spark plugs, valves, and other components connect to the cylinder head. The camshaft opens and closes those valves in time with everything else. Your crankshaft takes the pistons' pumping motion and converts it to that rotary motion. The oil pan or sump stores the motor oil that's needed to lubricate the moving engine parts. Of course, you also have the myriad bearings, gaskets, rings, and gears that help everything fit together.

Warning Signs of Failing Engine Parts

Your engine is a modern marvel when everything's working as it should. Eventually, though, parts can start to weaken or go bad. Here are some indicators to look for:

• Stalling
