Well my friggin heater core decided to blow up this week-end. I can't even see out my windshield now, lol!

I was wondering what is involved in replacing a heater core in an 86 GT with A/C? Thanks

the hardest part is getting the hoses off the old heater core. they are practicly fused to the metal.
i wouldnt advise this but i just cut the hoses off and stretched them far enough to get tham on the new one.
but again, i dont advise what i did, because if i have to do another heater core chances are another cut and ill never have enough.

There usually is no need to cut the heater hoses to get them unstuck from the heater core pipes. Since you are going to throw away the old heater core anyway, carefully crush the hose where it is in contact with the heater core pipes. When I've done this the bond between the hose and the pipes breaks loose.

Thanks for your help. I actually had access to Michell online and got the procedure. It seems to be really simple. I bet it shouldn't take me any longer than an hour.
