why cant a hole be cut in firewall to replace heater core in 1989 mustang just replace it with new piece of metal curious has anyone ever tried this will it work it would make a hard job simple the next time
did anyone realize this thread is almost 4 years old?
I changed the heater core in my 87GT years ago, i remember wishing i would have taken a pic of all the stuff i had to remove to get at it. I changed it while parked on the street in from of my house and boy was that a mistake!
After all was said and done I couldn't believe how inexpensive the core was and how ridiculously expensive labor is...but at least i knew why in the case of the hidden heater core.
Has anyone ever tried to make a simpler way to the "hack job" method? I mean incorporating a clean cut out and rivet system to aid in future exchanges?
Usually I only change the core once if at all with each fox i get but it would still be good to know if i had to do it again on the same car it would be a 20 minute process instead of 2-3 hours.
Like some previous people stated it can be done in 1.5 hours once you get familiar with it!
