Key Features

• Nylon guide construction for controlled timing chain movement
• Specific-fit design for application-matched installation
• Shoe and bracket included for the guide assembly
• CAD-designed and manufactured with advanced materials
• Tested for function and durability
• Built to support quiet, maintenance-free operation

Detailed Description

The Cloyes 9-5309 timing chain guide serves as the track that helps route and stabilize the timing chain between the crankshaft and camshaft. Cloyes uses CAD-based design and advanced materials to produce a guide that meets OEM-level performance expectations while maintaining consistent chain control under engine operation. The white nylon construction and specific-fit dimensions support accurate replacement in the intended engine applications.

This part is relevant for owners servicing timing components on Cadillac DTS, Cadillac STS, and Buick Lucerne engines, as well as other listed Cadillac and Oldsmobile applications. If you are replacing the chain, Cloyes recommends inspecting related timing components at the same time, since the guide works with the tensioner and sprockets to keep the chain properly supported and tight. The 9-5309 is a direct replacement timing chain guide for the specified lower guide positions.

What It Helps Address

• Timing chain noise caused by worn guide surfaces
• Chain tracking issues from damaged or degraded guide material
• Improper chain support in the lower timing assembly
• Service needs during timing chain replacement on listed vehicles
• Wear-related loss of stable chain routing in the valve train

Installation Notes and Tips

Verify the engine application and guide position before installation, since this part is specific to certain lower guide locations. Inspect the chain tensioner and sprockets during service, and replace related timing components as needed to restore proper chain control. The 9-5309 uses two mounting holes and does not include bolts.
