Are you saying clamp the IC pump return line and drive? I just didn't want to drive with a tool clamped to a hose Im willing to if thats your method.

I just didnt see how the pump could spin faster when driving since its not belt driven, it just gets a constant electrical connection.

Hey you're the man so I'll clamp it and drive later today. My guess is leave the radiator cap on since the car is going to slosh it around?
