Check the belt
The belt is automatically tensioned with
a tensioner.
Inspect the alternator belt and the
fan drive belts for wear and for
cracking. Replace the belts if the
belts are not in good condition as
shown A and B.
Slippage of loose belts can reduce
the
efficiency
of
the
driven
components. Vibration of loose belts
can cause unnecessary wear on the
following components:
Belts, pulleys and bearings.
CAUTION:
If the belts are too tight, unnecessary
stress is placed on the components.
This reduces the service life of the
components.
Check the fan
Check the fan to be sure it is securely
mounted; tighten the cap screws as
necessary. Check the fan for wobble or
bent blades.
Check the exhaust gas color
During the normal running of gas
engine, the color of exhaust air is light
grey. When the color changes, check
the cause and do troubleshooting.
