Product Details

This Cloyes timing chain tensioner is part of the Timing Chain Tensioner line, a product group focused on maintaining timing system stability across a wide range of engine applications. Cloyes has supplied timing system components since 1921, and the 9-5977 reflects that experience with a metal-bodied, spring-and-guide configuration built for precise chain control. It is used in timing systems where proper chain tension is critical to keeping camshaft and crankshaft timing aligned in Cadillac CT5, Escalade, CTS, Chevrolet Silverado 1500, Tahoe, Camaro, Corvette, and GMC Sierra and Yukon applications. For timing system integrity, Cloyes recommends replacing the chain, tensioners, guides, and sprockets together during service.

Common Timing System Issues

Excess timing chain slack
Chain noise from a worn or weak tensioner
Inconsistent camshaft timing control
Timing system wear during high-mileage service
Need for a direct replacement timing chain tensioner on supported Cadillac, Chevrolet, and GMC engines

Installation Notes

Install the tensioner according to the vehicle service procedure and verify correct chain alignment before closing the timing cover. Because this part uses an activation pin and includes a mounting bracket and shoe, confirm all mating timing components are inspected for wear before assembly. Cloyes recommends replacing the chain, guides, and sprockets at the same time to help restore full timing system integrity.
