The Drive Belt Tensioner Assembly for GM Vehicles is a solid replacement part for those experiencing issues with their current tensioner assembly. The installation process was straightforward and the part seems to be functioning properly. However, the pulley used in this assembly seems to be of lower quality compared to the original factory pulley, which has caused some concerns for durability in the long-term. While the price point may be attractive to those looking for a cheaper alternative to a GM branded part, it is important to consider the potential trade-off in quality. Overall, this assembly is a decent replacement option but may not be the best choice for those looking for a high-quality, long-lasting solution.
