Agility Autoparts HVAC Heater Core P/N:9010385
Keep the cabin warm and defrost the glass with the Agility Auto Parts HVAC Heater Core 9010522, a direct-fit replacement for the 2006-2011 Buick Lucerne and 2006-2011 Cadillac DTS. The heater core routes hot engine coolant through its fin-and-tube matrix so the blower can push warm air into the passenger compartment — if the original core is leaking coolant, fogging the windshield, or leaving you with weak heat, this replaces it.
See the Buyer's Guide tab for the full engine-level application details.
