4.4 Checking fan belt tension
Tools required
•
Sonic belt tension meter
1.
Check
the tension of fan belt at the position (A)
between the fan drive pulley and alternator pulley
with sonic belt tension meter.
NOTE
• If the measurement
is out of the service
specifications, loosen the alternator
mounting screws and adjust its position.
