Your vehicle’s belts and hoses are involved in processes within the cooling system, air conditioning system, charging system, and engine. These belts and hoses play crucial roles in functional operations inside your vehicle. The heater hose and radiator hose carry liquid coolant to and from the engine, radiator, and heater core. The timing belt is responsible for maintaining engine precision by synchronising the rotation of the crankshaft and camshaft, which move the engine’s valves and pistons. However, not all vehicles contain timing belts. In place of timing belts, some vehicles use timing chains. On the outside of the engine, the serpentine belt transmits power from the front of the engine to other systems in the vehicle, like the air conditioning system and charging system.
