I have a 1989 Ford Mustang Convert. I have a Kenne Bell Supercharger on it and now i am having Anti-Freeze Flowing into to over flow overflowing it while eptying the Radiator so it would overheat anyone now what would cause that i didn't have any trouble until supercharger was on it?

 

The boost probably spit a head gasket out. I'm having a wee bit of trouble in you desciption of the problem. I took it that you installed the supercharger and then it started blowing coolant back out of the overflow. How long have you had the KB on before the problem? Was it tuned? How many miles on the engine?

 

Have you burbed your coolign system???
