Radiator Cooling Fan Motor: Testing and Inspection
Noise
Sometimes there is fan noise under the following conditions:
^
The clutch is engaged for maximum cooling
^
The first 15 seconds to one minute after start-up. Until the clutch can redistribute the silicone fluid to its normal disengaged operating condition
(after settling 2 - 4 hours).
Fan noise or an excessive roar generally occurs under all high-speed conditions (2,500 RPM or higher) if the clutch assembly is locked up due to
internal failure. If the fan cannot be rotated by hand or there is a rough grating feel as you turn the fan. Replace the fan clutch.
