Operation 19. Check condition and tension of engine cooling system fan belt
Check the belt for traces of wear or damage. If necessary, replace it.
To check the alternator fan belt tension, apply a force of about 40 N to the middle point of
its crankshaft pulley to alternator pulley generator branch as shown in Fig. 8.4.13. The deflection
must be 12 to 17 mm. If necessary, adjust the belt tension. To adjust the belt tension, loosen the
alternator fastening. By turning the alternator housing, adjust the belt tension. Tighten up the strip
fastening bolt and the nuts of the alternator fastening bolts.
