go to parts store and buy a haynes manual for that car. did you go to auto zone.com and look this up? they give you location and if not there click on diagram.

You can bypass the Heater core for the short, if money + time is the issue.

There are several brands of STOP LEAK so get one and follow directions on label. Not only for radiators but heater core to.
The more expensive ones seem to work better. Make sure the presure cap is good because it needs to get hot and build up pressure for the stop leak to be pushed in the leaking hole. Anti freeze doesn't help but you can't do without it now. No other way to fix it right but tear out the dash and replace the core. Possiblity the hose could be leaking & tighten the clamp a little. You'll have no heat but clamp off the water out & in lines on the engine and take a warm blanket. Or run a hose from the out connection on the engine to the return and by pass the heater.
