Maintain a reliable oil cooler seal with this Genuine Nissan Oil Cooler Assembly O-Ring, designed to suit Nissan Patrol Y60 GQ models fitted with the TB42E EFI petrol engine. This O-ring seals the engine oil cooler assembly to the engine block and plays an important role in preventing engine oil from escaping around the oil cooler connection.

The oil cooler O-ring is constantly exposed to engine oil, high temperatures and operating pressure. Over time, the original seal can harden, become brittle or crack, allowing oil to leak from the oil cooler assembly. If the seal fails completely, it can result in significant oil loss and reduced engine oil pressure, potentially causing serious engine damage.

Replacing a worn or deteriorated oil cooler O-ring helps restore a secure seal between the oil cooler assembly and engine block and helps prevent oil leaks. This Genuine Nissan replacement is manufactured to Nissan specifications and provides the correct fit for the TB42E EFI engine.
