Cloyes 9-5518 Engine Timing Chain Tensioner - Upper

Cloyes 9-5518 Timing Chain Tensioner

The Cloyes 9-5518 timing chain tensioner is a direct-fit engine timing chain tensioner for select Toyota, Pontiac, and Chevrolet applications. Built with a cast body and a hydraulic/spring chain design, it helps maintain proper chain tension for consistent valve timing and quieter operation.

As part of the Cloyes Timing Chain Tensioner line, this component is CAD designed and manufactured with advanced materials, then tested for function and durability to meet or exceed OEM performance requirements. It is a specific-fit replacement for upper timing chain applications on vehicles such as the Toyota Corolla and Toyota Matrix.

Detailed Description

Cloyes 9-5518 is engineered to maintain the correct tension on the timing chain, helping the chain stay properly loaded during engine operation. This matters in upper timing chain service on vehicles such as the 1999-2008 Toyota Corolla, 2003-2008 Toyota Matrix, 2000-2005 Toyota Celica, 2000-2005 Toyota MR2 Spyder, 2003-2008 Pontiac Vibe, and 1999-2002 Chevrolet Prizm. The part number 9-5518 is also referenced under Remy 95518 for the same application.

Cloyes recommends replacing the chain tensioner, sprockets, and guides when servicing the timing chain. That approach helps restore proper chain control and reduces the chance of repeat timing system noise or wear after repair.

What This Part Helps Address

• Timing chain slack
• Chain rattle or noise from the upper timing area
• Irregular valve timing caused by weak chain tension
• Wear in the timing chain system after service
• Loss of tension control in hydraulic or spring-loaded designs

Installation Notes and Tips

Verify engine application and upper-position fitment before installation. This tensioner is a specific-fit part, so confirm the vehicle year, make, model, and timing chain layout against the catalog listing. For timing chain service, inspect the guides and sprockets at the same time and replace worn components as needed. Follow factory service procedures for chain alignment, tensioner setup, and final timing verification.

Quality Assurance

Cloyes designs and manufactures this timing chain tensioner using CAD-based engineering and advanced materials, then tests each part for function and durability. The 9-5518 is built to meet or exceed OEM performance requirements for the listed applications.
