Troubleshooting
Fan is not spinning or spinning too slowly.
Check the viscous clutch mechanism. Ensure the fan support is not seized and the fan belt has proper tension. If the viscous clutch is faulty, the entire support may need replacement.

Inspect the fan support bearings for wear. If the bearings are damaged, the viscous fan support unit should be replaced.
Engine overheating.
