Heater core

I have a 79 ta and my heater core is leaking. How hard is it to put a new one in.
Thank you

it's a royal PITA. I need to replace mine, but since it was already bypassed I think I'm going to keep it that way until the car gets a repaint.

It's a bigger pain in the ass than an engine swap.. lol... It blows royal chunks. I just pulled mine when pulling the heater box and stuff, and I don't even want to think about putting it back in.... Heres an idea............... STOP LEAK!!!!!!!! lol...

It's even more fun if your car has AC. ;) :cry:

Ya mine has AC so i guess im just going to by pass it and be done with it.

Pull the inner fender pull the glove box some of the bolts are on the inside and some on the outside. its not a bad job just takes time if your car is a fair weather only car gut all of it and make a flat panel to fill the hole. It took me around 2 hours from start to finish.
