Re: What did you do with your truck today, Part 3
I picked up my water pump from the machine shop today. They turned the heater hose mount down to 3/4" to accept the A/N compression fitting. This is done by turning the cutter on a boring head backwards and running the mill in reverse. The problem is holding the pump solid enough to do this. I didn't want to disassemble it. They made a special jig for the job. One outlet is for the heater and the other for the drag radiator. I had to shorten the neck on the fitting to get enough for the collar to compress. This fitting is rated at 250 PSI but I'm running waterless coolant so there will be no pressure in the system. I spent some time working on the thermostat housing also.
