Changing the water pump is a piece of cake. To change the pump (on the 3.1) 1.Disconnect the water hose from the pump, catch the coolant below with a wide drip pan. 2.Using a serpentine belt removal tool (long thin rod with a 3/8 inch socket) loosen the belt tensioner and remove the belt from the alternator 3.Remove the 4 bolts from the water pump pulley. You will have to use a long screw driver to hold the pulley in place while you turn the bolts. Put the screw driver between 2 other bolts to keep it from turning. 4.Pop the pulley off. You may have to pry it off with that same screw driver if it's stuck on there. Be sure not to bend the pulley though. 5.Remove 5 bolts holding the pump in place, scrape off the old gasket, put on the new gasket with some sort of gasket dressing or sealant and pop in the new water pump. It only goes in one way or the holes won't line up.
