How to replace a evaporator core in a fox body mustang 

Someone used duct tape and did a hack job on my fox . Cut a lot of the plastic off the evaporator box cover . Is there a reason it’s sealed ? I was thinking of just putting duct ape again . Thanks ed

I guess if u can get to it..it would be tuff...

Yea,,unfortunately,,I didn't have any to begin with.

Wow,, did you make a video of it? Like to see how u did it..

Ford actually put those little channels in there as a guide to cut open with a cutoff wheel to get the evap out,the only other way i can see would be to split the case but 99.9 % of them have this glue thats beyond stout,you will break the case before it comes apart,granted the op did kind of a rough job due to not having the best tools available to him, this happens sometimes, been there done that. I have done a few with a 3 inch real skinny cutoff wheel and i took my sweet time and it came out pretty nice,that foam has to come off somehow to give you the most space available to do the job, the cleaner the cut the better of it will seal, so please share with us if you have a way to do it without cutting anything, you would be doing the Mustang community a huge favor,we dont even need a video , just a brief description will do, thank you.

@@dntlss I've replaced the heater core in my '79 twice. Bought a later (after '85) a/c box, replaced the heater core and evaporator and installed it in my '79. Last month, replaced both cores on my brother's '85 GT. Never had to cut anything to separate the case halves.

@@kat5168 The 87-93 box is glued together at the factory. The 79-86 box has clips so you can split the case easily. The channels are there to use a cut off wheel to access the core.

@@shroomhauler you can see ford wants you to buy the whole housing with evaporator for $1000- it was better the old way
