Maintain reliable coolant circulation and engine cooling performance with this Genuine Nissan Oil Cooler Bypass Water Hose, designed specifically for Nissan Patrol GU Y61 TB45 engines. Featuring a precision moulded 90-degree bend, this OEM coolant hose ensures proper coolant flow between the oil cooler and engine cooling system while maintaining factory fitment and reliability.
