General Information

 TOC

The radiator or fan shroud is used to direct all air-flow across the radiator fins rather than around the edges of the radiator.

An incorrect fan shroud or obstructions can reduce air-flow and cause the engine to run hot.

NOTE: Check to be sure air is not recirculating. Check for missing baffles.

Initial Check

 TOC

 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 to allow proper airflow through the radiator to provide adequate engine cooling.

Inspect the fan shroud for proper fan clearance, cracks, air leaks, and damage. Replace if necessary. Refer to the equipment manufacturer’s service manual for instructions.

Cummins Inc. recommends that fan clearance be between 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.
