Keep warm air moving through the cabin with the FOUR SEASONS heater core 90624, an aluminum heater core built as a direct-fit replacement for a range of late-'70s Ford, Lincoln, Mercury and Plymouth applications. It drops in for the 1979 Ford LTD, 1979 Ford LTD II, 1979 Ford Ranchero, 1979 Ford Thunderbird, 1979 Lincoln Mark V, 1979 Mercury Cougar and 1974-1980 Plymouth Trailduster. See the Buyer's Guide tab for the full engine-level list.
A heater core is a compact coolant-to-air exchanger: hot engine coolant flows through its tubes while blower air passes across the fins, warming the passenger compartment and feeding the defrost system. Signs it may need replacing include weak or no cabin heat, a sweet coolant smell, fogged windows or coolant seeping onto the floor.
- Aluminum core: the exchanger is built from aluminum.
- Heavy-duty construction: made for durability in service.
- O.E. fit, form & function: engineered to match the original in fit, form and function.
- Independently tested: checked for proven quality and performance.
Backed by Four Seasons and over 50 years of mobile A/C experience.
