Protect your engine’s oil cooling system and maintain proper coolant circulation with this Genuine Nissan Oil Cooler Hose to Water Pipe, designed to suit Nissan Patrol GQ and GU models fitted with the RD28 diesel engine. This OEM hose connects the oil cooler to the water pipe, helping regulate engine oil temperature and maintain reliable cooling system performance.

Over time, coolant hoses can deteriorate due to constant exposure to heat, pressure, coolant chemicals, and engine vibration. When a hose becomes cracked, swollen, or brittle, it can lead to coolant leaks, reduced cooling efficiency, and an increased risk of engine overheating and costly engine damage.

Manufactured to genuine Nissan specifications, this factory replacement hose provides precise fitment, dependable coolant flow, and long-lasting durability to help maintain your Patrol's engine reliability in demanding Australian conditions.
