leaks on 2003 Mitsubishi Eclipse

My car is a 2001 mitsubishi with a 2003 engine. It is leaking on the passenger side somewhere of water. It keeps over heating and I cant even drive it down the street any more. What can be the cause of this?

Sounds like your heater core has begun to leak as its located behind the glove box and will need replacement to stop the leaking and overheating. You can get a estimate here and locate a shop here
