Maintain correct coolant recovery and reliable cooling system performance with this Genuine Nissan Bottom Coolant Overflow Bottle Tank, designed to suit Nissan Patrol GU Y61 models fitted with the ZD30 and TD42Ti engines. This OEM low-pressure coolant overflow tank forms part of the factory twin overflow bottle system, collecting expanding coolant from the radiator and allowing it to return to the cooling system as the engine cools, helping maintain the correct coolant level and system efficiency.

Over time, the original plastic overflow bottle can become brittle, discoloured, crack, or split due to constant engine bay heat, vibration, and repeated heat cycles. A damaged overflow bottle can allow coolant loss, introduce air into the cooling system, reduce cooling efficiency, and increase the risk of engine overheating if left unrepaired.

Manufactured to Genuine Nissan specifications, this high-quality overflow bottle provides precise fitment, durable heat-resistant construction, and long-lasting reliability. It is the ideal replacement during cooling system repairs, preventative maintenance, or when replacing cracked or ageing factory coolant reservoirs.
