Tubes installed, and I just specifically asked if the O rings were also installed with them.
Yes, one plate. I was on the phone with CVF and Cold Case tech support today.
CVF says cast impellers on the pumps they provide (the good ones vs stamped steel). Yes, it turns in the normal direction and the belt is on correctly, no slippage.
According to Cold Case, they like .060 clearance, and I am sure it's no less than 1/16th inch. I am going to pressure test the radiator and cooling system while it's running and see if the pressure drops when RPMs go up. THAT would indicate a water pump impeller efficiency problem.
