- 1). Place a five-gallon drain pan underneath the radiator drain valve on the driver's side of the radiator. Loosen, but do not remove, the drain valve with a 19 mm wrench turned in a counterclockwise direction. Allow the coolant to drain completely from the radiator then tighten the drain valve.
- 2). Open the hood. Remove the overflow hose from the white plastic coolant tank at the top of the engine with a pair of pliers. Remove the three holding screws from the tank with a 5/16-inch nut driver. Remove the tank from the engine bay.
- 3). Remove the upper radiator hose by squeezing the clamps with a pair of pliers while pulling the hose from the radiator and the water pump. Place a ½-inch ratchet wrench into the square hole on the serpentine belt tensioner at the top of the engine. Rotate the wrench counterclockwise to slacken the belt tension. Slip the belt from its pulleys and remove it from the engine bay. Slowly raise the handle of the wrench and remove it.
- 4). Remove the two bolts from the top of the plastic fan shroud with a 10 mm wrench turned in a counterclockwise direction. Remove the center nut that holds the fan to the front of the water pump with a 1 7/8-inch wrench turned in a counterclockwise direction. Lift the fan shroud and the fan together from the engine bay, being careful not to damage the radiator fins.
- 5). Pull the electrical connectors from the coolant temperature sensor and the cam position sensor on the face of the water pump. Loosen and remove the nine bolts that attach the water pump to the front of the engine block with a 10 mm wrench turned in a counterclockwise direction. Carefully pry the water pump from its mating surface with a flat blade screwdriver and remove it from the engine bay.
