Keep your cooling system operating at factory reliability with this Genuine Nissan Top Radiator Hose, designed specifically for Nissan Patrol GU Y61 models fitted with the TD42T diesel engine. This OEM upper radiator hose connects the top of the radiator to the engine, allowing hot coolant to circulate efficiently through the cooling system and maintain stable engine operating temperatures.

Over time, radiator hoses can deteriorate due to constant exposure to high coolant temperatures, pressure cycles, engine vibration, and age-related rubber fatigue. When the hose begins to fail, it may crack, swell, soften, or leak coolant. A failing upper radiator hose can lead to coolant loss, overheating, and potential engine damage if not replaced promptly.

Manufactured to genuine Nissan specifications, this direct-fit replacement restores factory cooling system integrity and ensures consistent, reliable coolant flow.

Common Signs of Wear

• Coolant leaks from upper radiator hose
• Cracks, swelling, or soft spots in hose
• Visible coolant residue near hose clamps
• Engine running hotter than normal
• Hose collapsing or bulging under pressure
