I'm about to send my 1993 FD motor out to have it rebuild but the water pump housing is holding me back. I removed everything....water pump, thermostat, and thermostat housing and now I just have the water pump housing left. I have a big enough gap to stick a screwdriver between the housing and the motor but one of the studs rusted together with the housing. If I move the housing around, I could see it move around the other studs freely except for that one stud.



Any suggestions on how to separate the two? Thanks for the help.

 

either remove the stud or get a bigger hammer
