Maintain the performance of your cooling system with this Genuine Nissan Radiator Overflow Bottle Tank, designed to suit all Nissan Patrol GQ Y60 models and selected GU Y61 models. This OEM coolant expansion tank captures excess coolant as it expands during engine operation and returns it to the radiator as the engine cools, helping maintain the correct coolant level and preventing air from entering the cooling system.

Over time, the original plastic overflow bottle can become brittle, discoloured, or crack due to constant heat cycles and engine bay temperatures. A damaged overflow bottle can lead to coolant leaks, coolant loss, and air entering the cooling system, increasing the risk of engine overheating and costly engine damage. Replacing a worn or leaking bottle helps restore cooling system efficiency and reliability.

Manufactured to Genuine Nissan specifications, this radiator overflow bottle tank is engineered for precise fitment, excellent durability, and long service life. Supplied complete with a new cap, it is the ideal replacement for cooling system repairs, preventative maintenance, or restoring your Nissan Patrol to factory operating condition.
