What does a fan belt tensioner do?

A fan belt tensioner is a critical component within the engine cooling system of heavy commercial vehicles. It functions as a spring-loaded unit that maintains the driving belt at the correct tension, preventing slippage and ensuring the cooling fan rotates at its designed speed. This component is essential for maintaining stable engine temperatures during heavy-duty operation.
