The Pontiac Montana engine will overheat if the coolant gets low and is not refilled properly. If coolant is added, an air block WILL OCCUR preventing proper circulation unless owners manual is followed. There are 2 blleeder valves in coolant system. They must be opened & closed in proper sequence (see manual) or engine will overheat. I know-been there!
