Spectra 94576 HVAC Heater Core - Front

Spectra 94576 HVAC Heater Core

The Spectra 94576 HVAC heater core is a direct-fit replacement for select Ford and Mercury applications that use a standard output heater. Built for vehicles without A/C in many truck and van applications, it helps restore cabin heat performance when the original core is leaking, restricted, or no longer transferring heat efficiently.

What It Helps Fix

• Weak or uneven heat from the dash vents
• Coolant odor inside the cabin from a leaking heater core
• Fogging or film on the windshield caused by heater core seepage
• Restricted coolant flow through the HVAC heater circuit
• Loss of cabin comfort in Ford E-150, E-250, and E-350 vans

Installation Notes

Verify the vehicle’s HVAC configuration before ordering, especially whether it is equipped with air conditioning and whether it uses the standard output heater arrangement. Confirm the part number 94576 against the existing core and vehicle application before installation. On Ford E-Series vans and related passenger models, access typically requires removal of HVAC components, so compare the replacement unit to the original before reassembly.

Spectra Premium states that its engineering, manufacturing process, and quality control are used to produce heater cores that meet or exceed the performance of the original equipment they replace. Part number 94576 is built as an OE-style HVAC heater core replacement for the listed Ford and Mercury applications.
