Any body know where the radiator hole is at on top to poor water too? My car is over heating and i can't seem to find it. Cause my car was leaking water took it to the shop and they said they couldnt find any leaks. WTF? and now its over heating? Im thinking water in the radiator is out or low thats why its causing this but I'm not sure. Seems like pontiac solstice is different from some other car cause usually the radiator will have a top where you could poor water in.
