Two things...are u saying a busted gasket or oring would cause the excess pressure? From what u just said, maybe I didn't make my self clear. Looks like you think I have a steady leak, I don't. I do loose coolant when I'm riding. So back to my original post, would the loose clamp to the water pump cause excess pressure which would cause me to loose coolant while riding??
