Installation Notes

Verify core dimensions, tube size, and heater box layout before installation. Compare the original heater core to Four Seasons 96128 to confirm fitment, tube orientation, and hose connection size. Proper flushing of the cooling system is recommended before installing a replacement heater core to help reduce contamination that can shorten service life.

Because heater core access often requires dashboard or HVAC case disassembly, installation is typically performed during a full heating system repair. Confirm vehicle-specific fitment for the exact Ford, Chevrolet, or Dodge application before ordering.
