Genuine Nissan O-ring Vac Pump to Cover - Nissan Navara D40 & Pathfinder R51

This is a replacement O-ring that seals the engine's vacuum pump to its mounting housing, specifically for Nissan Navara D40 and Pathfinder R51 models fitted with the YD25DDTI engine. Located between the pump and the cover it mounts to, this O-ring is critical for preventing oil leaks from this common failure point.

Due to constant heat cycles and exposure to engine oil, the original O-ring can become hard, brittle, and flattened over time, losing its ability to maintain a proper seal. The most common sign of a failure is a persistent oil leak appearing from around the vacuum pump area. Installing a new, quality O-ring is the correct fix to restore a leak-free seal.

Product Features

• Prevents Oil Leaks: Directly replaces the failed original O-ring to stop common oil leaks from the vacuum pump assembly.
• Durable Material: Manufactured from high-quality materials designed to withstand engine bay heat and resist degradation from oil, ensuring a long-lasting, reliable seal.
• Direct Fitment: Engineered as a direct replacement for the original part, ensuring straightforward installation without modification.
• Avoid Repeat Failures: Using a quality-sourced O-ring avoids the risks of inferior alternatives which can use incorrect materials, leading to premature failure, persistent leaks, and potential vacuum issues affecting brake performance.

This is a straightforward replacement for a competent DIY mechanic with basic tools. The primary challenge is often accessing the vacuum pump on the engine. It is recommended to have workshop cleaner or degreaser on hand to thoroughly prepare the mating surfaces before installing the new O-ring. To ensure a complete repair, any other gaskets disturbed during the job should also be replaced.
