Radiator Cooling Fan: Testing and Inspection

Cooling Fan Motor and Shroud
1. Inspect the fan blade and shroud for any foreign materials. Clear the obstruction and continue the test procedure.
2. Rotate the fan to determine if any contact between the shroud and blade exists. If contact is observed, install a new fan shroud assembly.
3. Rotate the fan by hand. The fan should rotate freely (no resistance should be felt, the fan will free wheel with minimum effort). If any resistance is present, install a new fan assembly.
