a VG30DE (TT) Motor it has , 24 valve duel over head cam 3.0 liter motor.





It may of just been over filled or a change in the outside air pressure may of caused it.





Keep an Eye on the Temp guage for a week or two.





As long as the temp guage reads normal , don't worry .......Just let it purge it self.
