hey i don't know how long i was driving the other nite with no water in my car. i was driving home and was tired so i don't ever remember looking down at my temp gauge. the next morining however i notice there was a wierd noise coming form my engine. like metal grinding turns out it was my water pump turning with no water in it. added water to it and found a hole in my radiator, everything seems cool though after i replaced the radiator. but i don't know if i messed up my motor or not. is there a way to find out?
