6.7L Cummins Cooling System – Cooling System Diagnostics – Fan Shroud Assembly

A fan shroud assembly is used to direct the airflow provided by the cooling fan. A missing or damaged fan
shroud will reduce the amount of air flow provided by the cooling fan and can cause an engine coolant overheat
condition.

Check the fan shroud for damage and/or contact with the cooling fan. Replace any damaged components. Refer to
Procedure 008-038 in Section 8.
