heater core

[milkyy]

I have a 1978 Trans Am with 13,000 KM and A/C. I need to change the heater core, any one out there know how I can Change it?

did you try picking up a chiltons manual or the original factory manuals from Helms. If you intend to keep the car it's worth having a shop manual. A general set of steps would be drain all coolant. Remove interior duct work on passenger side. Remove heater core box. Remove heater core. Maybe someone else will chime in with more specific instructions.

just don't over tighten the plastic duct work screws when you put it all back together. that plastic become very brittle...good luck...
