Genuine Nissan Oil Cooler Housing Large O-Ring - Nissan Navara D22 D40 / Pathfinder R51 YD25 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. The original rubber seal is exposed to constant heat cycles, causing it to harden, go brittle, and lose its ability to seal effectively. This is one of the most common causes of oil leaks on this engine. Failing to replace a leaking O-ring will result in a messy oil leak that contaminates your engine bay and driveway. If left unchecked, a minor leak can become a major one, potentially leading to low oil pressure and serious engine damage.NOTE: Does NOT suit Thai D40 models with VIN# starting with MNT.
