You shouldn't start the engine before you do the venting procedure. There will be air pockets throughout the engine block and head that may prevent the coolant from circulating properly and you may end up over heating the head. The venting procedure is the best part of having an electric water pump because you can bleed the air out without having to deal with hot coolant.
