After driving my stang for a while after changing my altenator I turned it off (temp gauge only half way up and got out and smelt coolant and saw it poouring out from underneath the car..filled back up and same problem this morning..after looking there is some near the overflow tank and some to the right (pass side) off radiator. No intake leak or anything I can see and seems to be comming from the top. Where should I start? What are the problem spots? I don't understand why it's blowing out or whatever but not running hot..only drove 10 minutes to work and drove easy! please help me out guy!
