Hello people my cadillac de ville overheated, last weekend the phenomenon occurred for the first time, I noticed it very late. my girlfriend made me aware that it was in front of squeal I called the amac he then opened the cooler cap and gave some gas then went again, even drove a longer distance. since I had the temp. display always in the eye, yesterday she suddenly got on what I stopped and called the amac (without qula men) he then did the same as the mechanic the week before.. then went again! today I drive to refuel again the indicator goes up(without qualamen) and after some gas again.. when I was at the tank I looked in front and everything was splashed with cool water! the water pump is brand new! it definitely can not be.. however when he is overheated a reinforced smoke development from the exhaust to watch. thanks for your help kev
