BINGO......When I was stripping my Maverick to make a drag car. I found it much faster and easier to get at the heater box by removal of the windshield.....this was an A/C car.
Smarter than me I was dumb enough to do my 88 5.0 Mustang. Boy, that was fun. And, since I'm not a very fast learner, I did it on my 85 Turbo Coupe. That one broke me of the habit. BTW, a sawsall was the tool of choice when I removed the heater and A/C box from my Mav drag car!
on a non- A/C car i removed the lower fiberglass part of the dash and glove box. from there it was all pretty straight foward. when my 88 town car started blowing steam i just ducktaped the upper vents closed so it didnt fog up my windshield and over power me with the smell of antifreez. no way i wanted to rip into that dash good luck
I did a heater core in a car over the winter that was in and out 4 times. Be careful of crappy workmanship and pressure test the core before you put it in. Nothing in life as deflating as putting in a heater core and filling the radiator and see coolant leaking from the passenger floorboard. Find out the recore was frozen in transit, after being pressure tested down south with straight water. Then next one was not soldered well, then the heater valve was not good, then the heater valve gasket was faulty.. oh yeah, I have lived heater core hell, anyone ever done a bandit edition Trans Am?

i know there definatly not fun on g-body gm's. the heater box is under the hood on the fire wall in a fiberglass box with the lid glued on. so there really is no way to get it apart without cracking it atleast once. not to mention taking half the windshield trim off olong the bottom of it. i assume 2nd gen f-bodies are pretty simular?
I use to have '79 Trans Am with a 6.6 engine......I had to change the heater motor. That was no picnic.....I could just imagine what the heater core was like.
I've just got around to starting the heater core replacement, but I don't know where to start at. It seems simple because I don't have any A/C, Would I start by removing the four bolts on the fire wall that are under the hood?
you need to remove the lower dash to expose the header box right behing the glove box. the heater core sits right in that black fiberglass box
you dont need to take the whole box out. the front clips on and can be removed. once you take it off the core's looking right at you if ou have nice carpet keep in mind that you'll probably be spilling some antifreez...
Wow thats weird because I removed the the inter part of the glove box, and removed the clamps on the heater box but I can't open it.
