b18c timing belt

The primary function of a car belt pulley is to guide and support the serpentine belt or timing belt, which wraps around the pulleys to drive multiple components of the engine. In essence, the pulley acts as a wheel or lever that helps facilitate the smooth operation of the belt. As the engine runs, the crankshaft turns, driving the belts, which, in turn, rotate the pulleys. This mechanical action enables the powered accessories to function, ensuring a vehicle can operate effectively without overheating or experiencing electrical failures.

The timing belt is a rubber toothed belt that connects the crankshaft to the camshaft(s). In engines with an interference design, the timing belt is even more critical, as it prevents the pistons from colliding with the open valves. When an engine is running, the crankshaft rotates the timing belt, which, in turn, drives the camshaft. This operation ensures that the engine’s valves open and close at the ideal moments during the intake and exhaust strokes.
