Water Pump Issue and question
Did you buy a GM pump or an aftermarket replacement? Some of them have some poor build quality. As for your question of EWP the pump comes with a plug for the drive. You have to clearance the front lip for some of the electric pumps. You also need to press the impeller shaft out of the pump to install the plug in the back of it. The only aftermarket electric pump that I know for sure doesn't require trimming of the fan shroud is the CSR pump.
I will look into the CSR pump also.
