Any tips on removing and replacing the heater core? It sprung a leak, so it's on my list to do before winter. I'm thinking I should remove the complete heater box, and spliting it out of the car. Anyone done this? TIA

The heater core is in the box. So you have to remove the whole thing. While you are at it, you should also get new foam seals and rebuild the whole box. You should even go for the gold and change your heater hoses also. Just in case...

Steve on my non A/C 68 it was a breeze, disconnect the hoses, unbolt the blower motor, take out the glove box (just in case) and out it came. My a/c equipped 68 sucked big hairy shivvy's... it was an all day project with the carpet and glove box already out...

65-66 is a ball buster job Steve. You still have to pull the entire box out to get at the heater core. Put in a high quality US made unit as you do not want to do this again. The A/C equiped small FoMoCo's are the absolute worst ones to do though as Marcus says. Alex

Thanks guys!

I've opened the box before (under the dash) to get media blasting material out of it. I would rather wrestle aligators that work on my head under a dash with my feet putting prints on the headliner! Know what I mean? Oh I'm looking forward to this, can you tell

I did my sisters 66 (non-a/c) without taking the box out, the hardest thing was getting the hoses and clamps on and off between box and firewall.

My daughter and I replaced the core, all the foam seals, the blower motor, and the defroster duct (definitely worthwhile to get one of the plastic replacements), cleaned and painted the works, and had it back in place in an afternoon. Hardest part for us was holding the unit in place under the dash while getting the nuts started on the studs. One person with eight-foot long arms that had three elbows apiece could do it alone, no problem!

Not wanting spit in the chowder--but now would be the time to shine some light into the cowl area to make sure there are no holes. It's just one of those facts of life with old Mustangs. Hope all is ok.
