Four Seasons HVAC Heater Core P/N:90057
Keep warm air flowing to the cabin with the FOUR SEASONS heater core (P/N 98590A), an aluminum-core direct-fit replacement for the 1967-1971 Ford Thunderbird, the 1970-1972 Lincoln Continental, and the 1968-1971 Lincoln Mark III. In this hvac heater core, hot engine coolant circulates through the core while the blower motor pushes cabin air across its fins, warming the passenger compartment and feeding the defrost vents.
Weak heat, a sweet coolant odor inside the cabin, fogged windows, or damp carpet are common signs a heater core may need replacing — if a failed core is the cause, this unit replaces it. Backed by more than 50 years of Four Seasons mobile A/C experience. See the "Vehicles it fits" section to confirm the engine for your vehicle.
