The timing belt is a rubber belt, often reinforced with fiberglass or other materials, that connects the crankshaft to the camshaft in an engine. Its primary function is to synchronize the rotation of the crankshaft and camshaft, ensuring that the engine’s valves open and close at the appropriate times during each cylinder's intake and exhaust strokes. This precise timing is crucial for maintaining the engine's efficiency and performance, as it helps prevent misfires, optimizing fuel combustion and power output.

To understand the fan belt's role, we must first consider its basic function. The fan belt, also known as the serpentine belt in many modern trucks, connects various engine components to the crankshaft. Its primary purpose is to drive the vehicle’s cooling fan, which is essential for regulating the engine temperature. In addition, the fan belt powers other critical accessories, including the alternator, power steering pump, and air conditioning compressor. This multifunctionality underscores its importance in the overall operation of a truck.
