Spectra Premium HVAC Heater Core P/N:94552
Help put warm air back into the cabin with the Spectra Premium heater core, part number 94571. Its aluminum core, tanks and tubes carry hot engine coolant so the blower can push heated air through the vents. It is a direct-fit replacement for many vehicles, among them the 1975-1979 Ford F-150, 1973-1979 Ford F-250 and 1971-1973 Ford Mustang. See the Buyer's Guide tab for the full list.
If a leaking or clogged core is behind weak cabin heat, a sweet coolant smell or fogged windows, this HVAC heater core replaces it. Other cooling and climate-control parts can cause the same symptoms, so diagnose the system before you replace the core. Country of origin: China.
