• Cross-reference part numbers include 12635048 and 24461834

Detailed Description

Cloyes 9-4201 is an engine timing chain designed to keep valve events synchronized with crankshaft rotation. The chain uses CAD-designed construction and premium materials, with precision pitch control to promote proper tooth engagement at the sprockets. This part number is used across a wide range of GM and Saab applications, including Chevrolet Malibu, Chevrolet Equinox, GMC Terrain, Buick LaCrosse, and Buick Regal models, as well as select Saturn, Pontiac, and Saab vehicles.

This part cross-references 12635048 and 24461834 for the same application. For timing drive service, Cloyes recommends replacing the chain tensioner, sprockets, and guides at the same time to restore system stability and accurate timing.

What It Helps Fix

• Excessive timing chain stretch
• Rattling or noise from the timing drive
• Camshaft and crankshaft timing correlation issues
• Rough running caused by worn timing components
• Timing instability in center-mounted engine applications

Installation Notes and Tips

Verify application by year, make, model, and engine configuration before installation. This timing chain is a specific-fit part for center timing drive applications, so matching the original chain pitch, length, and timing mark layout is important. Inspect the tensioner, guides, and sprockets for wear during service, and replace any worn components to help maintain proper timing alignment.

Quality Assurance

Cloyes designs and manufactures timing drive components using CAD-based engineering, premium materials, and extensive testing for function, fitment, and durability. The 9-4201 is built to meet application-specific timing requirements for supported vehicles.
