Removal and installation of the fan and fan coupling

It is necessary to replace the Vyazkostny coupling, if the nave has teases. Thus the fan at the motionless engine does not rotate or rotates hardly. It is necessary to replace the coupling 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.


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

The nut has the left carving.

At an otvorachivaniye of a nut compress maple a belt of the pump of cooling liquid, holding thus a nave from rotation. If the nut sits very strongly, strike with a hammer on a key for a nut otvorachivaniye. (Repair trucks of BMW apply for this purpose the special tool holding a pulley for heads of bolts). After a nut otvorachivaniye completely to unscrew it it is possible rotation of a krylchatka. Thus 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 a narrow screw-driver. Address to 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 vyazkostny coupling, turn out bolts of fastening and take out the coupling. Address to an accompanying illustration.


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

For an exception of damage of a carving and the coupling by no means it is impossible to tighten bolts too strongly. (Address to an accompanying illustration).

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