Well on my drive i drove it today 55 miles and it was runing cool below normal most of the drive and when I got home not kowing I let it idel and revved it (5-7)times2 to3 thousand RPM,and then let it idle then it happened steam and hissing (a lot) All of the fluid draind out through the radiator cap. when this happened I looked at my gauge and it said it was in normal temperature and my fan did not turn on. I shut it off quickly and let it cool down and filled it with straight radiator fluid. I ran it a couple of times, it stopped steaming and it does not put any smoke out the pipes which is good meaning my block and gaskets are probably fine. I don't get how it can over heat when the sensors read cool. or because I revved it to many times and it built up pressure and it started steaming. I was at home when all this happend.Something is up with my whole electrical and cooling system. My dad said my block is fine but I still want to take it in toget it looked at.
I am so upset about this. My parents said to me it is just a machine but to me a Mustang is more than a machine.
