3.6.24. Checking the engine belt
• With the engine running, visually check the ventilator
belt pulley - whether it is not vibrating and whether the
belt runs with its all surface on the tensioning pulley.
• Stop the engine!
• Lift the belt-tensioning pulley using the lever and
remove the belt.
• Check visually the belt, search for its damage. Cracks
perpendicular to the belt are not defects. In case any
lengthwise cracks appear on the belt or its edges are
frayed or its parts torn out, it is necessary to exchange
the belt.
• Check the axial clearance of the ventilator belt pulley
- it must not exceed 0.15 mm (0.006 in).
• Mount the belt back.
Checking the tensioner:
• Check the tensioner belt pulley and arm for cracks.
