What does a fan belt tensioner do?

This fan belt tensioner plays a critical role in the engine cooling system by maintaining the correct tension on the fan belt. By providing constant pressure, it prevents belt slippage and ensures the cooling fan rotates at its designed speed, which is essential for preventing engine overheating in heavy commercial vehicles.
