I've vented the system by carefully holding a shop rag under the thermostat housing, engine running and warm, and just cracking loose the brass vent plug on the t-stat housing. I don't want any anti freeze dripping onto the timing belt pulley on the crankshaft below... yeah I'm pretty cautious about that!
Sounds like your water pump should be fine, if it's that new.
