Removal and installation of the fan and coupling of the fan

The viscous coupling needs to be replaced if the nave has teases. At the same time the fan at the motionless engine does not rotate or rotates hardly. The coupling needs to be replaced also if the axial or radial gap exceeds 0.6 mm. For check it is necessary to move the fan in different directions. Oil should not follow from a nave.

 REMOVAL

1. Turn off a bolt of fastening of the fan a key of 32 mm and remove it. Address an accompanying illustration.

The nut has the left carving.

At an otvorachivaniye of a nut squeeze maple a belt of the pump of cooling liquid, holding thus a nave from rotation. If the nut sits very strongly, strike with the Hummer a key for a nut otvorachivaniye. (Auto repair shops of BMW use for this purpose the special tool holding a pulley for heads of bolts). After a nut otvorachivaniye completely it is possible to turn off it rotation of a krylchatka. At the same time it is necessary to pay attention to that the krylchatka did not fall.

2. Disconnect a fan cover from above at the left and on the right. For this purpose take out a pin the narrow screw-driver. Address an accompanying illustration.

3. Press a fan cover from above in the center and disconnect a pad.
4. Take out the fan together with a cover upward.

5. If it is necessary to disconnect a krylchatka from the viscous coupling, turn out bolts of fastening and take out the coupling. Address an accompanying illustration.


 INSTALLATION

1. Insert the viscous coupling into a krylchatka and tighten fastening bolts the moment of 10 Nanometers.

For an exception of damage of a carving and the coupling it is impossible to tighten bolts too strongly at all. (Address an accompanying illustration).

2. Insert a fan cover with the fan from above so that the lower levels of fastening entered eyes on a radiator.
3. Insert clips and fix them by pins. Replace the damaged clips or pins.
4. Fix the fan to a nave of the pump of cooling liquid by the moment of 40 Nanometers. At the same time a nave hold for maple a belt or for heads of bolts.
