1994 Pontiac Sunbird was driven for three months without coolant until it overheated a day ago. It overheated on the way home and started smoking out of the air vents. That night, I filled it with...


i assume the shop was talking about heater core being bad and even if heater core is bad they should be able to test for a head gasket being bad actually you can totally bypass the heater core so there no reason to fix that before you check for a head gasket being bad
and if you have run for three months without coolant you will be extremely lucky if the head gasket not blown or head or block cracked
i would do nothing about the heater until car is checked for blown head gasket
honestly i would take the car some where else because they are either trying to screw u or have no idea of what there doing

How to replace heater core in 1992 Pontiac Sunbird


You should get a Haynes manual. You have to go on the inside of the vehicle and remove the panels, to get to the heater core. Then you have to jack the vehicle up to remove the heater core from the hoses. This is a tedious job and takes time. But not to difficult. I'm not a mechanic, and it took me about 4 hours.

I have a 1994 Sunbird V6 that is Leaking Coolant from an Elbow coming out from the Firewall. How do I stop this?


Aside from disconnecting your heater hoses, the only fix is to replace the "heater core". The "heat" function of your climate control system relies on heated engine coolant to work. The small elbow that you describe, is most likely the condensate drain. The "heater core" and the "evaporator core(for the a/c)", are located beneath the dash assembly in an enclosed housing. The "heater core" should be serviceable without removing the complete housing as with some vehicles. I hope this helps
