Maintain efficient engine cooling and exhaust gas recirculation performance with this Genuine Nissan EGR Straight Heater Hose, designed for early-model Nissan Patrol GU Y61 vehicles fitted with the ZD30 Di diesel engine. This OEM heater hose carries engine coolant to the EGR (Exhaust Gas Recirculation) cooler/heater assembly, helping regulate exhaust gas temperatures and reduce emissions while enabling proper cabin heat circulation.

Over time, original EGR heater hoses can deteriorate due to constant exposure to heat, coolant chemicals, and engine bay stress. A cracked, swollen, or brittle hose may lead to coolant leaks, reduced heater performance, EGR heater inefficiency, and possible engine overheating if not addressed promptly. Replacing worn hoses with genuine components is essential for maintaining engine reliability and emissions systems performance.

Manufactured to Nissan factory specifications, this genuine ZD30 Di EGR heater hose ensures correct fitment, secure sealing, and long–lasting durability. It is specifically suited for early-model GU Y61 ZD30 Di Patrols and is ideal during cooling system or EGR maintenance.
