Maintain reliable coolant circulation and heater performance with this Genuine Nissan Heater Inlet Hose, designed to suit Nissan Patrol GU Y61 models fitted with the TB48 4.8L petrol engine. This OEM heater hose connects the heater core to the heater hose joiner on the firewall, allowing coolant to circulate through the heater system for effective cabin heating while supporting correct engine cooling system operation.

Over time, heater hoses can deteriorate due to constant exposure to engine heat, coolant pressure and age. The rubber can harden, crack or split, leading to coolant leaks, poor heater performance and the risk of engine overheating. Replacing it with a Genuine Nissan component restores reliable coolant flow, maintains heater efficiency and ensures a precise factory fit.
