Maintain proper engine cooling performance with this Genuine Nissan Bypass Water Hose, designed specifically for Nissan Patrol GU Y61 models fitted with the TB45 petrol engine. This OEM hose connects the oil cooler to the coolant pipe, allowing correct coolant circulation through the bypass system.

Over time, coolant hoses can harden, crack, swell, or develop leaks due to constant heat cycles, pressure, and age. A damaged bypass hose can lead to coolant loss, overheating, and potential engine damage if not replaced promptly.

Manufactured to Nissan’s original specifications, this direct-fit replacement hose ensures correct coolant flow, secure sealing, and long-term durability in demanding engine bay conditions.
