Agility Autoparts HVAC Heater Core P/N:9010171
Keep warm cabin air flowing with the Agility Auto Parts HVAC Heater Core 9010529, a direct-fit replacement for the 2005-2009 Ford Mustang (see the Buyer's Guide tab for engine-level applications). The heater core acts as a small heat exchanger, circulating hot engine coolant through its tubes and fins so the blower can push warmed air into the passenger compartment and to the defrost vents. When the original core leaks or clogs, you may notice weak or no heat, sweet-smelling coolant odor inside the cabin, foggy windows, or coolant residue on the floor — signs this part may need replacing.
Agility offers a complete line of automotive heaters covering a large share of North American vehicle applications.
