Re: Heater core replacement help.
Autozone has some very rudimentary info about heater cores on Tempo/Topaz. Hopefully, the heater core ittself is still intact and is not damaged. One thing you might want to check is if the hoses in the engine compartment leading to the core (through the firewall) might have been plugged/cut off. If so, then it might just be a matter of locating and replacing with new hoses -- and hoses/clamps are not expensive.
If that works, then the rest is just making sure the water circulates back to the heater core and any air bubbles get pumped out.
Beyond that, if the heater core actually needs to be replaced, it is a big deal involving removing the dash board, so buying a Chilton's or Haynes manual (or both!) will really help you figure out the surgery.
I feel more like I do now than I did when I got here.
