This is the Genuine Nissan Timing Chain Tensioner O-ring. It sits between the timing chain tensioner and the engine block. This O-ring is crucial for maintaining correct oil pressure to the timing chain tensioner. Neglecting to replace a hardened or damaged O-ring can lead to oil leaks and reduced tensioner performance, potentially causing timing chain rattle or even failure.
This NDK-spec O-ring is used on both timing chain tensioners, meaning two are required per vehicle for a complete service. It can also be found on the front of the timing cover, located behind the Cam Sprocket Cover Assembly on the passenger side (LH) of the engine. The O-ring for the driver side (RH) is a different part (150662Y510) and is available separately.
Choosing genuine Nissan parts ensures the quality and fit for your vehicle. Unlike many aftermarket alternatives, genuine Nissan parts are manufactured to exacting standards, using materials specifically designed to withstand the rigors of Australian conditions. This guarantees original performance, service life, and long-term reliability for your Nissan.
