[updated:LAST EDITED ON 12-Dec-02 AT 02:07 PM (EST)]My heater core in my 78 F150 is suspected to be plugged with corrosion as the first motor in the truck was full of it, and the heater doesn't work like it should. I was wondering how hard it is to replace the heater core, b/c I know some can be very stressful. I would appreciate the info.
Thanks

Harrison takes about 1 1/2 hour to do - no A/C. If your truck has A/C I would seriously consider paying Ford to do it and investing your time in something more fun.
it's not the nicest thing in the world to do.. but it can be done... best to buy a haynes manual. it tells you where the bolts that you can't find are....
