Have you heard a rattle under the hood of your Chevrolet truck after installing a new compressor? The noise you hear may be caused by the belt tensioner.

Have you heard a rattle under the hood of your Chevrolet truck after installing a new compressor? The noise you hear may be caused by the belt tensioner.

Did you know that if the compressor failed due to liquid slugging that it will cause premature failure of the belt tensioner? This failure could cause an under hood rattling noise on 2000 to 2008 Chevrolet Trucks. Liquid Slugging has been known to cause A/C Compressor failure, resulting in the need of a new compressor. If the belt tensioner and serpentine belt are not replaced at the same time, it may generate a noise under the hood. This noise can be mistaken for a premature compressor failure. The typical life of a belt tensioner is 60,000 miles. Some common causes for replacement of tensioner are: loss of tension , bad bearing , or a damaged pulley.

The Global Parts Distributors part number for the belt tensioner is 4011375. We highly reccomend checking this tensioner anytime you service a 2000-2008 Chevrolet truck.
