CAUTION
The fan shroud must be installed correctly, be in good
condition, and the shroud-to-fan clearance must be
within the manufacturer's specifications for proper
airflow through the radiator to provide adequate engine
cooling.
Inspect the fan shroud for proper fan clearance, cracks, air
leaks, or damage. Replace, if necessary. Refer to the equip-
ment manufacturer's service manual for instructions.
Cummins recommends fan clearance be 5.08 to 10.16 cm
[2 to 4 in] from the radiator core. Refer to the equipment
manufacturer's service manual for alternative positions.
