Cloyes 9-5659 Engine Timing Chain Tensioner - Left Upper

Cloyes 9-5659 Timing Chain Tensioner

The Cloyes 9-5659 timing chain tensioner is built for engine timing systems that rely on controlled chain tension for accurate valve timing. This engine timing chain tensioner uses a hydraulic/spring design with an activation pin, a nylon/aluminum shoe, and a spring-included construction to help maintain proper chain tension in the left upper position.

Compatible With Ford Explorer, Ford Flex, Ford Taurus, Lincoln MKT, Lincoln MKS, Mazda CX-9, Mazda 6, Ford Fusion, Lincoln MKZ, Ford Edge, Lincoln MKX, Ford Taurus X, and Mercury Sable applications that call for this upper-left timing chain tensioner. Part number 9-5659 is also referenced as 95659.

Detailed Description

Cloyes timing chain tensioners are CAD designed and manufactured with advanced materials, then tested for function and durability to meet or exceed OEM performance requirements. The 9-5659 timing chain tensioner is engineered to maintain proper chain tension in the engine’s valve train, helping support stable timing operation in Ford, Lincoln, and Mazda applications. If you are servicing a timing chain system on a 2013-2019 Ford Explorer, 2009-2019 Ford Flex, or 2008-2019 Ford Taurus, this part number 9-5659 is a direct-fit service component for the specified left upper position.

Cloyes also recommends replacing the chain tensioner, sprockets, and guides together when the timing chain is replaced, since these parts work together to keep the chain properly tensioned and aligned.

What It Helps Address

• Timing chain slack in the upper-left engine timing path
• Noise caused by worn or weak chain tension control
• Irregular valve timing from a tensioner that no longer holds pressure
• Wear on timing chain guides and related valve train components
• Service issues during timing chain replacement on Ford, Lincoln, and Mazda engines

Installation Notes and Tips

Verify engine code, model year, and left upper position before installation. This tensioner uses an activation pin and is not manually adjustable. For timing chain service, inspect the chain, guides, and sprockets at the same time and replace worn components together to restore proper timing system operation. Confirm application details in the catalog before ordering.

Quality Assurance

Cloyes timing chain tensioners are manufactured to meet or exceed OEM performance requirements and are extensively tested for function and durability. The 9-5659 is built to deliver a quiet, maintenance-free timing system experience in the listed Ford, Lincoln, and Mazda applications.
