Warning: Before proceeding with this procedure, you should wait until the engine has completely cooled down.
Note: During this procedure, you must use a special wrench for the fan drive clutch (GM# 46406 or equivalent).
1. Unscrew the bolts and push out the pins that secure the air intake plate to the radiator supports and remove it.
2. Disconnect the transmission cooling lines from the bracket located on the engine and from the fan shroud.
3. Disconnect the electrical viscous coupling connector from the housing.
4. Disconnect the upper hose from the radiator. Be prepared for coolant spills.
5. Turn counterclockwise and remove the drive coupling bushing from the coolant pump.
6. Disconnect the casing from the side panels and move the radiator along with the condenser forward. This operation can be conveniently performed with the assistance of an assistant.
7. Remove the fan and shroud assembly by lifting the elements vertically, while keeping the radiator and condenser pushed forward (see illustration).
5.7. Lift and remove the fan, shroud and clutch assembly
8. If necessary, unscrew the bolts securing the fan to the coupling. It should be noted that these bolts should be tightened to a certain torque (see specifications in this chapter).
9. Installation is carried out in the reverse order of removal. Tighten the nut that secures the drive clutch bushing to the required torque.
10. Check the coolant level and top up if necessary (see _ chapter 1).
