Genuine Nissan Oil Cooler Oring Set - Nissan Navara D22 D40 & Pathfinder R51 YD25 VSK

This Genuine Nissan oil cooler o-ring set is located between the engine oil cooler assembly and the engine block on YD25 diesel engines. These seals are critical for preventing engine oil and coolant from either leaking externally or mixing internally. The original rubber seals are exposed to constant heat cycles, causing them to harden, compress, and eventually fail. A failed seal can cause a catastrophic mix of oil and coolant, contaminating both systems and leading to major engine damage, or it can cause a severe external leak. Replacing these seals is essential preventative maintenance to protect your engine.

This Set includes:
1 x 21304BN301
This is the Large Oil Cooler Oring that goes between the oil cooler housing that the water hoses connect to, and the engine block underneath the oil filter housing.

1 x 2133430F0A
This is the Small Oil Cooler Oring for the banjo bolt used in this oil cooler assembly.

These are Genuine Nissan Orings for quality fitment and seal.
