How to replace the heater core on a 1985 Ford Crown Victoria LTD. The procedure for removal and installation should be the same for the Grand Marquis and Town car of the same vintage. This job was kind of a pain, but worth it since winter is coming. Be careful when buying the replacement core, I tried to buy at autozone, and their system calls for the wrong one for this car, part number 94622. the correct part number for the autozone / spectra premium core is 94620.
My Dad's 1998 Lincoln Town Car has a heater core leak and after sitting for a year he needs it repaired so the car can be daily driven. I remove the heater box as well as the dash board from the car to complete the repairs. I have step by step instructions included in the video.
