After the system has been drained, remove the upper and lower radiator hoses and then take off the radiator support brackets. The radiator is now free so pull it out of the car, being careful not to leak any coolant onto the vehicle. Now you're ready to remove the water pump studs. They are of various lengths, so be sure to mark them so you know which one goes where during reassembly. You can take out the two bolts that secure the thermostat housing, and then remove the heater supply hose from the heater line on the lower intake manifold. At this point, take off the heater bypass hose, which runs from the thermostat housing to the water pump. You can also leave it on and remove all of the pieces together.
