On the summer of 2007, I was driving on the freeway and I had to pullover to the side because my Hummer H3 started overheated. I did the proper procedure of refilling coolant to my car, but within 4 hours it leaked. I was driving for 30 min. With windows down. Not using the air conditioner. I took it to the dealership because I was still under warranty and supposedly "fixed" the problem. It is April 2008 and the other day my car shut down on me again because my car overheated. I checked all cooling placed and I refilled them with dex-cool coolant. The next morning I checked the coolant tanks and they were empty.
