OK

Below is a print and the directions for replacing.

  1. Disconnect the negative battery cable.
  2. Properly drain and recover the coolant to a level below the thermostat.
  3. Unfasten the coolant inlet housing bolt, which is accessible through the exhaust manifold.

  1. Raise and safely support the vehicle.
  2. Remove the radiator outlet pipe stud.
  3. Remove the second coolant inlet housing bolt, then remove the coolant inlet housing.
  4. Remove the thermostat, then clean the old gasket material from the mating surfaces.

To install:

  1. Position the thermostat in its correct location, then install the coolant inlet housing using a new gasket. Tighten the retaining bolt to 19 ft. lbs. (26 Nm) on the 2.3L and 10 ft. lbs. (14 Nm) on the 2.4L engine.
  2. Install the radiator outlet pipe stud.
  3. Carefully lower the vehicle.
  4. Install the coolant inlet housing bolt through the exhaust manifold.
  5. Properly fill the cooling system.
  6. Connect the negative battery cable, remove the radiator cap, then start the engine. Allow the engine to run with radiator cap removed, until the upper radiator hose becomes hot (thermostat open). With the engine idling, add coolant to the radiator until the level is up to the bottom of the filler neck.
  7. Install the radiator cap, making sure the arrows line up with the overflow tube.
