Maintain the integrity of your cooling system with this Genuine Nissan Radiator Cap Blank, designed to suit selected Nissan Patrol GU Y61 and Y62 models, along with various Nissan Navara applications. This OEM blanking cap seals the radiator filler neck on cooling systems that utilise a separate pressurised coolant overflow bottle, helping prevent coolant leaks and ensuring the cooling system operates as designed.

Unlike a standard pressure radiator cap, this blank radiator cap does not contain a pressure relief valve. Its purpose is to provide a secure seal at the radiator while system pressure is controlled by the pressurised overflow bottle. Over time, the rubber seal can harden, crack or deteriorate, while the locking tabs may become worn or damaged. A faulty cap can allow coolant to escape, increasing the risk of engine overheating and costly engine damage. Replacing a worn cap is simple preventative maintenance that helps maintain reliable cooling system performance.

Manufactured to Genuine Nissan specifications, this radiator cap blank delivers precise fitment, durable construction and dependable long-term sealing performance. It is the ideal replacement when servicing your cooling system or replacing worn factory components.
