My 1997 grand prix GT is leaking coolant and I am lost! The leak is coming from the drivers side and seems to be coming from behind the radiator or on the bottom of it but I cannot pin point the leaks location. The temp gauge does not enter the red but is between 210 and the red at its hottest and thats when coolant leaks pretty bad. Also while driving the temp goes down but if I am sitting at a light the temp rises quickly again. Any ideas what could be the issue? I think it is the radiator but I want to make sure before I take things apart and look for the leak! Any help would be great! Thanks
