What is an automatic belt tensioner assembly

The serpentine belt that drives the accessories on late model engines has an automatic belt tensioner that keeps the belt tight. The typical service life of a serpentine belt is about 60,000 miles or five years. When the belt nears the end of its life, it may become cracked, glazed and noisy.

If an aging belt is not replaced, it may break causing a loss of drive torque to all of the engine's accessories. When the water pump stops turning, the flow of coolant stops and the engine begins to overheat. When the alternator stops turning, there is no charging output and the battery starts to run down. When the power steering pump stops turning, the steering suddenly gets very stiff and hard to steer.

Most people know the belts are a maintenance item and eventually have to be replaced. But many do not know the spring-loaded automatic tensioner that keeps a serpentine belt tight can also wear out or become weak. This can cause a variety of problems if the tensioner is not replaced when a new belt is installed.

Automatic belt tensioner assembly critical quality

Belt tension is critical. Too little tension may allow the belt to slip and squeal. Slippage also causes the belt to run hot and age prematurely. And if the belt is really loose, it may come off its pulleys. Too much tension on a belt may overload the belt as well as the shaft bearings on the water pump, alternator, power steering pump and air conditioning compressor, possibly leading to premature failures in these components, too.The automatic belt tensioner assembly is recommended for replacement when replacing the serpentine belt.
