Fig. Fig. 2: After the fan mounting nuts have been removed, slide the fan assembly forward and place inside the radiator shroud

  1. Loosen and remove the drive belts.
  3. Remove the bolts that retain the fan shroud to the radiator support. Remove (if there is enough room between the fan blades and radiator) or position the shroud back over the water pump and fan assembly, if necessary to gain working room.
  5. Loosen and remove the fan to water pump mounting bolts or nuts and remove the fan assembly. Don't lay the fan, if equipped with a fan clutch, on its side. Fluid could be lost and the fan clutch might require replacement. Inspect the condition of the fan blades, if any are cracked or damaged, replace the fan.
  7. Install the fan assembly in position on the water pump and pulley. Secure the fan assembly with the mounting nuts or bolts. Tighten the nuts to 69-70 inch lbs. (8-11 Nm). Install the shroud and drive belts. Adjust the drive belts to the proper tension.
