I've got a 1999 pontiac firebird 3.8L V6 with a bad water pump. I have acquired the replacement parts including a new water pump and a new thermostat, I have done this repair before, however I have never done it to my car or a car like mine. Since this is a daily driver of mine I would like to get step by step instructions of how the procedure should be done according to my specific vehicle.
