This is a Genuine Nissan timing chain tensioner for the YD25 engine, designed specifically for Spanish-built (VSK) Nissan Navara D40 and Pathfinder R51 models manufactured from January 2010 onwards. This tensioner is for the upper, double-row timing chain that connects to the camshaft sprockets. Located deep within the engine, its job is to apply constant hydraulic pressure to the chain guide, maintaining the correct tension and ensuring precise valve timing.

As a critical wear component, the tensioner's internal mechanism can weaken over time, leading to a loss of tension and excessive chain slack. A common symptom of a failing tensioner is a rattling noise from the engine, which is often most noticeable during a cold start-up. Replacing a faulty tensioner is crucial preventative maintenance to avoid the risk of the timing chain skipping a tooth, which can result in catastrophic engine damage.

Product Features

• Critical Engine Protection: Maintains precise tension on the upper timing chain, protecting against chain slack and potential valve-to-piston contact.
• Durable Construction: Built from high-grade materials specifically designed by Nissan to withstand the heat, pressure, and stress of a modern turbo-diesel engine.

Replacing the timing chain tensioner is an involved workshop job that requires significant engine disassembly to access the timing components. This task should be performed by an experienced mechanic with specialised timing tools. When this tensioner is replaced, it is highly recommended to install a complete timing chain kit at the same time. This typically includes the timing chains, guides, sprockets, and any related seals or gaskets to ensure a comprehensive and reliable repair.
