94 Cavalier 2.2L overheating

Ok, here's what's going on. About 4 days ago I noticed that I was leaking what looked to be anti-freeze. After checking under the hood I found that it was not leaking from the radiator or resevoir but from a small L-shaped hose coming from the firewall area. I had a friend look at it and he said it was just the A/C overflow valve. He didn't know why it was green though. I have never used the A/C. Now I am having a problem with it overheating. Driving is fine, but when I stop or idle the temp guage goes all the way over to the red and then the "check guages" light comes on. The fan has not been working since I noticed the above mentioned leak. Also while driving it seems like the car doesn't want to accelerate properly. It seems sluggish. I had a similar problem about 2 years ago and had to have the waterpump replaced. Anybody have any ideas?

Your question MUST be answered in one of these threads.

Found out it's a bad heater core. For now I just bypassed the heater core, replaced the thermostat, and replaced the fan relay. Everything is fine for now. Of course the heater core will need to be replaced before winter.

Cool glad you figured it out so fast.
