Withdrawal
Release the fan shroud from the top left and right clips. To do this, push out the expansion pin of the clamp with a narrow screwdriver and then open the clamp. Pull the fan cover up.
Unscrew the fan from the water pump hub with a 32 mm wrench.
Attention: The nut has a left-hand thread, when unscrewing it should be turned to the right.
When loosening the nut, press on the water pump V-belt to keep the hub from turning. If the nut cannot be unscrewed, to unscrew it, hit the handle of the wrench on the nut with a hammer. Do not allow the fan impeller to fall.
Remove fan.
If it is necessary to separate the viscous coupling from the fan, unscrew the 4 mounting bolts and remove the coupling.
Installation
Insert the viscous coupling into the fan and tighten the fastening bolts with a tightening torque of 9 Nm.
Attention: To avoid damaging the threads and the coupling, do not overtighten the mounting bolts.
Screw the fan with clutch onto the water pump hub with a tightening torque of 25 Nm. At the same time, keep the hub from turning with a V-belt.
Caution: Do not twist the nut.
Place the fan shroud on top so that both lower mounting strips fit into the radiator lugs.
Insert clips and secure with pins. Replace damaged clips and pins.
