Just got back from a fishing trip, towing up and down the sierra mountains. Noticed when the fan clutch engaged I would get the normal loud whoosh of the fan and it would cycle on and off. The thing which caught my ear was when the fan clutch disengaged there was a metallic-whine which would last a few seconds and then go away. That seemed to happen each time the fan clutch locked and unlocked. Could that be a bearing in the fan clutch going bad? The noise does not happen at any other time, just when the clutch unlocks the fan.
