Further information

The serpentine belt is a long, continuous belt that drives multiple accessories on the engine, such as the alternator, power steering pump, and air conditioning compressor.

The belt tensioner is typically mounted to the engine block or a nearby bracket, and is designed to apply a specific amount of tension to the serpentine belt. This tension ensures that the belt remains in contact with all of the pulleys on the accessory drive system, allowing it to effectively drive each accessory.

The Detroit belt tensioner is typically spring-loaded, using a spring mechanism to maintain tension on the serpentine belt. When the tensioner is properly adjusted, the belt should have just the right amount of tension to prevent slipping or skipping, but not so much tension that it causes excessive wear on the belt or the accessory drive components.

If the belt tensioner is not functioning properly, it can cause a number of issues with the engine and accessory drive system. Common symptoms of a failing belt tensioner include belt noise, belt slippage, and decreased accessory performance.

Replacing the belt tensioner on a Detroit engine typically involves removing the old tensioner and installing a new tensioner that is designed to fit the specific make and model of engine. It is important to follow the manufacturer's recommended installation procedure and torque specifications to ensure proper fit and function of the new tensioner.
