Genuine Nissan Lower Timing Chain Tensioner YD25 - Nissan Navara D22 & D40

This is a Genuine Nissan lower timing chain tensioner for Nissan Navara D22 and D40 models fitted with the YD25 engine. It is engineered specifically for the single-row timing chain that connects to the crankshaft sprocket, a critical component for engine synchronisation. As a genuine OEM part, it guarantees the precise fitment and material quality Nissan demands for long-term reliability.

Located inside the engine behind the front timing cover, this hydraulic tensioner applies constant, correct pressure to the lower timing chain. This function is essential for maintaining accurate engine timing, preventing chain slack, and ensuring smooth operation. A worn or failing tensioner is a common cause of engine rattle, and if left unchecked, can lead to jumped timing and significant internal engine damage.

Product Features

• Genuine Nissan Quality: Manufactured to exacting OEM standards for guaranteed reliability and service life in the critical timing system. Using an inferior aftermarket part risks catastrophic engine failure.
• Maintains Engine Timing: A precisely engineered hydraulic mechanism ensures correct tension is applied to the lower timing chain, preventing slack and potential timing jump.
• Direct-Fit Replacement: A direct replacement for the original part, ensuring correct fitment and function without any modification.

Installation Notes

Replacement is a complex workshop job that requires significant engine disassembly to access the timing components and is not recommended for DIY installation without advanced mechanical experience. For a complete and reliable repair, it is highly recommended to replace the timing chains, guides, and seals at the same time. Consider a full timing chain kit for a comprehensive overhaul.
