Re: over heating

This is just an idea. Try running the engine without a thermostat.

That may or may not help the overheating.

Only other thing I would consider, is that you got a bad pump. Maybe the blades were installed wrong (backwards) during assembly. I would take it off and return it for either an exchange or refund.
There is a reason Checkers has a lifetime warranty. They know some of the pumps they sell are turkeys, but that may be 1 out of 100.

Re: over heating

I have had new thermostats stick in closed position when install new. A few light taps on the house usually causes them to open up and work as intended. I did this with motor running and starting to get hot (thermo should have been opening up), gave it a couple of taps and it made a loud pop when it opened. This is real bad about happening if you used some type of adhesive to install the water neck gasket. I can't imagine it has a air pocket in it (unless your radiator is mounted lower than the water neck) or that the pump is turning the wrong way (I could be wrong, but am quite sure all reverse turning pumps are long style intended for serpentine belt use). If none of this helps, it is possible you have a head gasket leaking compression into the water jacket. Just some point to consider, good luck getting it going!

Re: over heating

Well seeing as how we are grasping at straws here, this might work if it is an airpocket in there. Drain the coolant back out and remove the heater hose that goes to the intake and refill the radiator. Just be ready to put the hose back on or you'll have a nice mess! This gives the air a place to escape. Worth a shot anyway.
