Restore reliable cabin heating and windscreen demisting with this Genuine Nissan Wide Heater Core Assembly, designed to suit Nissan Patrol GU Y61 models. This OEM heater core is located within the heater box deep inside the dashboard and transfers heat from the engine coolant to the cabin air, providing effective interior heating and windscreen defrosting.

Over time, heater cores can become blocked with sediment, deteriorate due to corrosion, or develop coolant leaks as a result of age and general wear. A faulty heater core can cause poor cabin heating, coolant loss, a sweet coolant smell inside the vehicle, persistently foggy windows, or wet carpet on the passenger side. Replacing a damaged or leaking heater core helps restore effective heating and demisting while preventing further coolant loss.

Manufactured to Genuine Nissan specifications, this wide heater core assembly is designed for precise fitment, efficient heat transfer, and reliable long-term performance. It is the ideal replacement for a leaking, blocked, or damaged factory heater core when restoring your Nissan Patrol GU Y61 to factory operating condition.
