Ok guy's,
So I too thought a 3/8" hole seemed a little large, what is the correct size hole, or holes that should be there? I do not have a thermostat bypass hose and need some help there.
I can get the engine up a slope and verify all of the air is out of the system though and will try to do it soon. I take it you think the pump may be cavitating?
The overflow sump is there and it has a 16 pound radiator cap I believe that would blow to it if it were to blow.
I will try to verify all the air is bled out before going too much further.
