This is a Genuine Nissan upper timing chain tensioner for the YD25 engine. It is specifically designed for the double row timing chain that connects the camshaft sprockets, located at the front of the engine behind the timing cover. The tensioner's primary function is to maintain correct hydraulic pressure on the chain, preventing slack and ensuring precise engine timing for optimal performance and reliability.

As a critical engine component, using a Genuine Nissan part is essential for longevity and correct operation. This tensioner is a direct-fit replacement for specific Spanish-built (VSK VIN) Nissan Navara D40 and Pathfinder R51 models. A worn or failing tensioner can lead to a rattling noise from the front of the engine, and if left unchecked, can result in the timing chain skipping teeth, leading to catastrophic engine damage.

• Durable Construction: Manufactured from high-grade materials specifically designed to withstand the rigours of a turbo-diesel engine and Australian conditions.

Installation Notes

Installation of this component is a complex workshop job that requires significant engine disassembly, including the removal of the timing cover. This procedure requires specialized tools and a high level of mechanical skill to ensure the engine timing is set correctly. When replacing the tensioner, it is highly recommended to also replace the timing chain, guides, and sprockets as a complete kit. You will also require new timing cover gaskets, seals, fresh engine oil, and coolant to complete the job.
