This is a Genuine Nissan upper timing chain tensioner designed for Nissan Navara D22 and D40, and Pathfinder R51 models equipped with the YD25 engine. Located at the top of the engine, this component is critical for maintaining consistent and correct tension on the timing chain, which is essential for proper engine timing and performance.

Over time, the original tensioner can wear out, losing its ability to hold the chain taut. A common sign of a failing tensioner is a distinct rattling noise or 'timing chain slap', often most noticeable when starting the engine from cold. Replacing a worn tensioner with a genuine part is crucial to prevent potential engine damage caused by incorrect timing.

Installation Notes 

Replacement of the timing chain tensioner is a complex workshop job that requires specific tools and a thorough knowledge of engine timing procedures. Incorrect installation can lead to severe and costly engine damage. When replacing this tensioner, it is highly recommended to inspect the timing chain and guides for any signs of wear. You may also require associated gaskets and seals to complete the job properly.
