Bring back warm cabin air and clear defrost on your classic Ford or Mercury with the Four Seasons Heater Core 96571. This aluminum heater core is the Ford F150 heater core that installs as a direct-fit replacement for 1975-1979 Ford F150, 1973-1979 Ford F250, 1978-1979 Ford Bronco, 1971-1973 Ford Mustang, 1968-1976 Ford Torino, 1971-1978 Mercury Cougar and many other Ford and Mercury models — see the Buyer's Guide tab for the full list.

The heater core is a small radiator inside the HVAC case: hot engine coolant flows through its aluminum tubes while the blower pushes cabin air across the fins to warm the interior and feed the defroster.

  • Heavy-duty construction for durability.
  • Quality engineering for O.E. fit, form and function.
  • Independently tested for proven quality and performance.
  • Backed by Four Seasons and over 50 years of mobile A/C experience.

Signs the original core may need replacing include weak or no heat, a sweet coolant smell inside the cabin, fogging on the inside of the windows, or coolant seeping onto the passenger floor. If a leaking or clogged heater core is the cause, this unit replaces it.
