Maintain the integrity of your cooling system with this Genuine Nissan Radiator Overflow Tank, designed to suit Nissan Patrol Y62 models fitted with the VK56 V8 petrol engine. Also known as the coolant expansion tank, this OEM reservoir stores expanding coolant as the engine heats up and returns it to the radiator as the engine cools, helping maintain the correct coolant level, eliminate air from the system and ensure efficient engine cooling.

Over time, the original plastic overflow tank can become brittle due to constant heat cycles, coolant exposure and engine bay temperatures. This can lead to cracks, coolant leaks and pressure loss, increasing the risk of overheating and cooling system failure. Replacing it with a Genuine Nissan component restores proper cooling system operation and provides the durability and precise fit expected from an OEM part.
