Agility Autoparts HVAC Heater Core P/N:9010303
Keep warm air flowing to the cabin with the Agility Auto Parts HVAC Heater Core 9010503, a direct-fit 2007-2017 Nissan Altima heater core that also drops into the front HVAC module of the 2009-2014 Nissan Maxima and 2011-2017 Nissan Quest. The heater core routes hot engine coolant through its fin-and-tube matrix so the blower can transfer that heat into the air passing through the dash vents.
If a leaking or clogged heater core is the cause of a sweet coolant odor inside, fogged-up windows, damp front carpet, or weak cabin heat, this unit replaces it. Diagnose the source before replacing, as those symptoms can have other causes.
