Genuine Honda drive belts and timing belts are designed to resist stretching and deterioration for maximum durability and performance
Depending on the model, the drive belt operates the water pump, the alternator, and the power steering pump. It also drives the air conditioning compressor on A/C equipped vehicles. Belt replacement is necessary if the belt becomes worn, damaged, or as the rubber deteriorates due to age or contamination. Belt failure can result in engine overheating, loss of power steering, inoperative charging system, and A/C.
The timing belt drives the engine's camshaft(s) to open and close the intake and exhaust valves at the proper time. On some Honda engines, the timing belt also drives the water pump to circulate the engine's coolant. Some engine models also have a second smaller timing belt that drives a balancer shaft system to cancel out engine vibrations.
Periodic timing belt replacement according to your Honda's maintenance schedule is critical to avoid belt failure and potential engine damage.
