Belt Tensioner, Idler & Pulley Information

Why are Belt Tensioner, Idler & Pulley Part(s) Important

Belt Tensioner, Idler, and Pulley are all important to your car's cooling system. About 66% of the energy produced by your engine is wasted as heat energy and must be dissipated to prevent overheating. The engine's cooling system is series of tubes send coolant around the engine with the purpose of absorbing the heat and rushing the wasted energy away. The belt tensioner, idler, and pulley help to keep the coolant moving through your cooling system.

The belt tensioner, idler, and pulley are necessary external parts to the cooling system. On vehicles that don’t have the newer electronic water pumps, they keep the water pump running. Depending on the vehicle, there is either a single serpentine belt or a series of belts that drive the external components. The belt tensioner, idler, and pulley make sure that the water pump's belt is at the proper tension to drive the pump, ensuring the proper speed to keep the coolant circulating and the engine cool.
