Cloyes 9-5549 Timing Chain Tensioner

The Cloyes 9-5549 engine timing chain tensioner is built for specific Ford, Mazda, Mercury, and Lincoln applications that use an upper timing chain tensioner. It uses a hydraulic/spring design with an activation pin and cast construction to maintain proper chain tension in service.

Key Features

• Engine timing chain tensioner for specific upper timing chain applications
• Hydraulic/spring chain type with spring included
• Cast body with gray finish
• Specific fit design for direct application matching
• Activation pin style with two mounting holes
• CAD designed and manufactured using advanced materials
• Extensively tested for function and durability

Detailed Description

Cloyes 9-5549 is an upper engine timing chain tensioner engineered to maintain the correct amount of tension on the timing chain in select Ford Escape, Ford Fusion, Mazda 6, Mazda Tribute, Mercury Milan, and related vehicles. Proper chain tension helps keep valve timing stable and reduces the chance of chain slack during operation. Cloyes designs and manufactures its timing components with advanced materials and tests each part for function and durability to support consistent performance.

This part cross-references Ford OE number YF1Z6L266BA for the same application.

What It Is Used For

• Restoring proper timing chain tension in upper chain systems
• Replacing a worn or sticking tensioner on high-mileage engines
• Addressing timing chain noise caused by loss of tension
• Supporting stable valve timing in Ford Escape, Ford Fusion, and Mazda 6 applications
• Correcting chain slack related to hydraulic or spring tension loss

Installation Notes and Tips

Install this tensioner only on the specific upper timing chain applications listed in the fitment data. Cloyes recommends replacing the chain tensioner, sprocket(s), and guide(s) when the timing chain is replaced, since these components work together to keep the chain properly supported and tight. Verify engine application and position before installation.

Quality Assurance

Cloyes timing chain tensioners meet or exceed OEM performance requirements. The 9-5549 is CAD designed, manufactured with advanced materials, and tested for function and durability to help deliver quiet, maintenance-free operation in the correct application.
