I've been having problems with the PCNC 1100 coolant pump since purchased new several months ago. If I don't run the coolant pump every few days, the shaft sticks. The pump must be removed, the shaft manually rotated (using pliers), and then reinstalled for use. I thought maybe the coolant:water ratio was off, but I followed the recommendations on the bottle.
Is anyone else having problems like this with the coolant pump?
