Dorman - OE Solutions HVAC Heater Hose Assembly P/N:626-309
Keep hot coolant moving to your heater core with the Dorman - OE Solutions HVAC Heater Hose Assembly 626-598, an OE FIX upgrade and the Dorman heater hose fitting that swaps the failure-prone plastic T-connector for a more durable aluminum one. It's designed to match the original fit and function on the 2005-2020 Nissan Frontier (V6-4.0L), 2005-2012 Nissan Pathfinder (V6-4.0L; V8-5.6L for 2012), and 2005-2015 Nissan Xterra (V6-4.0L).
As a Dorman heater hose assembly, it routes engine coolant to and from the heater core so the system can deliver cabin heat. If the original hose or its plastic T-connector has cracked and is leaking coolant, this replaces it. Clamps are not included, so consult the vehicle service information for the correct clamps and installation. Country of origin: Thailand.
