1986F150Six Posted November 2, 2020 Share Posted November 2, 2020 Gary, might this be archived so one can see how the sealing was done by the factory? https://www.ebay.com/itm/Genuine-Ford-EOTZ-18476-A-E3TZ-18476-F-Heater-Core-Seal-Assembly-w-Insulation/143814405876?epid=1211134037&hash=item217c01aef4:g:CiUAAOSwfmFfnFHf Link to comment Share on other sites More sharing options...
Gary Lewis Posted November 2, 2020 Share Posted November 2, 2020 David - That's a good idea. See if you think I did it correctly: Documentation/HVAC and then the Illustration, Pics, Etc tab, then the Integral A/C tab, then the Pictures tab, then the Heater Core Insulation tab. Boy, that is COMPLEX! And where the pictures are is not accurate as that is a high output core, which could have been in the base heater, Comfort Vent, or Integral A/C. So the whole page needs to be revised. Any suggestions? Link to comment Share on other sites More sharing options...
Rembrant Posted November 3, 2020 Share Posted November 3, 2020 Ha! I actually just ordered a high output Heater Core for the old 1980 today. I figure I might as well remove the heater box. get it all cleaned out and install a new core while the front fenders are still off. It's a bit of a pain changing that core on a Non-AC truck.

Rembrant Posted November 3, 2020 Share Posted November 3, 2020 It certainly is. I know, right? That's why I want to do it now while there are no hood or fenders on this truck...lol. I saw somebody ask on FB the other day how long it took to change, and several people replied and said it was "easy peazy" and only a 10-20 minute job. On a factory AC equipped truck maybe, but not on a non-AC truck. Link to comment Share on other sites More sharing options...

On a factory AC equipped truck maybe, but not on a non-AC truck. It took me at least three hours to do mine as I had to take a running board off to do the heater in my truck.
