Maintain the correct cooling system pressure and protect your engine from overheating with this Genuine Nissan 118kPa (1.2 Bar) Radiator Cap, designed to suit selected Nissan Patrol GQ, GU TB48, Y62 VK56 and Pathfinder R51 models. This OEM radiator cap is engineered to maintain the correct cooling system pressure, helping increase coolant boiling point and ensuring efficient engine temperature regulation under everyday driving, towing, and demanding off-road conditions.

Over time, radiator caps can weaken due to worn springs, deteriorated seals, or corrosion. A faulty radiator cap can cause coolant loss, pressure leaks, overheating, reduced cooling system efficiency, and in severe cases, costly engine damage.
