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 synchronizing 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. Some factors that contribute to wear and tear on your belts and hoses include vehicle age, mileage, belt tension, hose clamp failure, electrochemical degradation, and oil contamination. In the long run, routine maintenance and replacements of your vehicle’s belts and hoses will prevent breakdowns and costly repairs.
