Maintain reliable coolant circulation with this Genuine Nissan Heater Hose to Water Pump, designed to suit Nissan Patrol GU Y61 models fitted with the ZD30 diesel engine. This OEM heater hose connects the metal coolant pipe on the passenger side of the engine to the water pump, ensuring efficient coolant flow throughout the cooling and heating system for reliable engine temperature control.

Over time, heater hoses are exposed to constant heat cycles, coolant pressure and engine vibration, causing the rubber to harden, crack or deteriorate. A leaking or damaged heater hose can result in coolant loss, poor heater performance and engine overheating, potentially leading to costly engine repairs. Replacing the hose with a Genuine Nissan component restores the integrity of your cooling system and provides dependable performance in all driving conditions.
