Maintain reliable coolant circulation with this Genuine Nissan Water Bypass Pipe, designed specifically for Nissan Patrol GU Y61 models fitted with the TB45 petrol engine. Located beneath the intake manifold, this OEM coolant pipe forms a critical part of the engine's cooling system, directing coolant between key engine components to help maintain optimal operating temperature.

Over time, the original bypass pipe can corrode internally or externally due to constant exposure to coolant, engine heat, and moisture. A leaking or damaged bypass pipe can result in coolant loss, engine overheating, and potentially severe engine damage if left unrepaired. Because the pipe is located beneath the intake manifold, it is highly recommended to replace it while the manifold is removed during major engine or cooling system servicing.

Manufactured to Nissan's original specifications, this genuine direct-fit replacement provides the correct fitment, durability, and coolant flow to ensure long-term reliability without the need for modification.
