Maintain reliable engine cooling and consistent cabin heating performance with this Genuine Nissan Heater Hose, designed for Nissan Patrol GQ Y60 and GU Y61 models fitted with the RD28T diesel engine. This OEM coolant hose is part of the vehicle’s heater circuit, carrying engine coolant between the engine and heater core to ensure proper temperature regulation and effective cabin heating.

Over time, heater hoses can deteriorate due to constant exposure to heat cycles, coolant chemicals, and engine bay pressure. A worn, cracked, or softened hose may lead to coolant leaks, overheating risks, reduced heater performance, or unexpected loss of engine coolant. Replacing aged hoses is essential preventative maintenance for maintaining engine reliability and preventing breakdowns.

Manufactured to Nissan factory specifications, this genuine replacement heater hose ensures correct fitment, secure sealing, and long-lasting durability under demanding driving conditions. It is designed specifically for RD28T-equipped Patrol models and is ideal for routine maintenance or cooling system restoration.
