This is a Genuine Nissan timing chain guide for the YD25 engine, specifically designed for the camshaft timing chain. It is located on the inner tension side of the chain assembly inside the timing cover, and suits early Spanish-built Nissan Navara D40 and Pathfinder R51 models up to January 2010.

Over time, this guide can wear down from constant contact with the chain or become brittle and break, leading to excessive slack. A common sign of a failing guide is a distinct rattling or slapping noise from the front of the engine, often more noticeable on a cold start. Replacing a worn guide is critical to prevent the chain from jumping, which can cause catastrophic engine damage.

Product Features

• Genuine Nissan Part: Manufactured to OEM specifications for perfect fitment, performance, and durability. Guarantees material quality as specified by the manufacturer.
• Durable Construction: Made from high-quality, wear-resistant polymer material designed to withstand constant heat and friction inside the engine.
• Prevents Engine Damage: Correctly guides the camshaft timing chain, maintaining precise tension to prevent costly internal engine failure. Using inferior guides risks premature breakage and severe engine damage.

Installation Notes 

Replacing this timing chain guide is a complex workshop job that requires significant engine disassembly to access the timing components. Specialised timing tools and a thorough understanding of the YD25 engine are necessary for correct installation. When this guide is being replaced, it is strongly recommended to replace the entire timing chain assembly, including all chains, tensioners, and other guides as a complete kit. A new timing cover gasket and front crankshaft seal are also typically required to complete the job properly.
