Cooling System:
•
Inspect the fan for blade damage. If damage is found, replace with
the recommended parts. Inspect for fan-to-shroud interference and
any damage to shroud, such as cracks and holes.
•
Do not change fan ratio or alter fan spacer dimensions and positions.
•
Inspect fan clutch for proper operation. Make sure the fan is
disengaged when cooling of the engine is not required.
•
Inspect radiator shutters (if equipped) for proper operation. The
shutters should be open during normal operating temperatures.
Engine:
Valve covers and block covers are made to damp-out engine
mechanical noise and, if needed, should be replaced with recommended
parts. Check for mechanical isolations.
Transmission Enclosure:
Inspect for cracks, holes and tears. Clean any
deposits, such as oil, dirt and stones.
Exhaust System:
•
Inspect for leaks at various joint connections and loose clamps.
•
Perform a visual inspection for cracks or holes in the muffler and tail
pipe.
•
Always use the recommended parts when items need to be replaced.
•
Do not change the tail pipe elbow or offset tail pipe orientation from
the standard position as originally received.
•
To avoid abnormal changes in vehicle sound levels, it is necessary for
the owner to perform inspections and necessary maintenance at the
intervals shown in the
Scheduled Maintenance
chapter.
