Quality item from a trusted brand
This AC drive belt tensioner was the perfect replacement item. My old tensioner pulley started to make a loud screeching sound when accelerating that made the engine sound horrible on my 2002 Chevrolet Silverado 1500. After replacing it. This new tensioner pulley eliminated all the unwanted sounds of the older one and is unnoticeable. It was very easy to replace and can be accessed from above or below, depending on which is easier for the installer. It fits perfectly and is built with quality materials. It keeps the belt tension exactly at the right level to eliminate belt slippage on the AC compressor. ... show more
