To start off the car I am working on is a 91 Mustang GT. Well I was getting ready to start my new setup today but ran into a snag when I went to put coolant in the system it would spill out pretty much as fast as I would pour it in. Seems there something not right with the water pump and timing cover I am using. The car that the motor came out of was a 95 GT so I had to change the timing cover over to a fox timing cover which I did. The cover I put on it is a carb timing cover but the water pump is for my 91. Is the fact that the cover is a carb cover and the water pump is off of a efi setup be my problem? I just find it kind of odd it would be because all of the mounting holes seem to be in the same place. Any help would be great and thanks again.
