Maintain correct cooling system pressure and reliable engine temperature control with this Genuine Nissan Radiator Cap, designed specifically for Nissan Patrol GU Y61 models. This OEM cap is rated at 110kPa (1.1 bar) and is responsible for sealing the cooling system, maintaining pressure, and preventing coolant loss under normal and heavy-duty driving conditions.

Over time, radiator caps can lose their sealing ability due to worn rubber seals, weakened springs, and heat cycling. A failing cap can cause coolant to escape, reduced system pressure, overheating, and inconsistent engine temperature, especially during towing, off-road use, or hot weather conditions.

Manufactured to genuine Nissan specifications, this direct-fit replacement restores proper cooling system pressure and helps ensure long-term engine reliability and efficiency.
