Overview

The Cloyes 9-6025 engine timing chain tensioner is a direct-fit timing system component for a wide range of Mercedes-Benz applications. It helps maintain proper chain tension so the valvetrain can stay synchronized under normal engine operation.

Fits 2012-2022 Mercedes-Benz models in the left upper timing chain position, including C43 AMG, E350, GLE350, and S450 applications. The 9-6025 is built for service work where timing chain control and consistent tension are critical.

Key Features

Engine timing chain tensioner for Mercedes-Benz timing system service
Spring or hydraulic tensioning design, depending on application
Supports proper chain tension for stable timing operation
Direct-fit replacement for the specified left upper position
Cloyes timing system component, part number 9-6025

Detailed Description

Cloyes 9-6025 is an engine timing chain tensioner used in Mercedes-Benz timing system repairs and maintenance. It is specified for the left upper position across multiple 2012-2022 Mercedes-Benz models, including E-Class, C-Class, GLE, GLS, SL, and related AMG variants. This part number, 9-6025, is intended for applications where the timing chain needs controlled tension to maintain accurate camshaft and crankshaft synchronization.

Cloyes timing components are known for service-focused engineering, and the brand recommends replacing the chain, guides, and sprockets together during timing service to maintain system integrity. This part cross-references Mercedes-Benz OE numbers 2760502500 and 276050250064 for the same application.

The 9-6025 is a practical choice for Mercedes-Benz timing chain service when the original tensioner is worn, noisy, or no longer maintaining consistent chain pressure. Use the vehicle-specific fitment data to confirm the exact application before installation.

Common Uses

Timing chain noise caused by weak or worn tension control
Chain slack that affects cam timing stability
Timing service on Mercedes-Benz engines with left upper tensioner placement
Replacement of a leaking or sticking hydraulic tensioner design
Restoring proper chain preload during engine repair

Installation Notes

Confirm the engine code and timing component layout before ordering. This part fits only the listed Mercedes-Benz applications and the left upper position shown in the fitment data. During timing service, inspect the chain, guides, and sprockets for wear and replace related components as needed.

Quality Assurance

Cloyes has supplied automotive timing systems since 1921 and backs its products with technical support and an industry-leading warranty.

This part fits 90 vehicles
