I'm having a whining/howling noise coming from my fan after I shutoff the engine, just wondering if anyone could tell me what they think could be causing the fan to do this? I sprayed some WD-40 into the clutch area, and that seemed to remedy the problem for a short while, but it still remains. I'm going to take the fan assembly apart tommorow and clean it off and rebolt it and see if that fixes the problem, but just wondering if anybody has any other ideas/suggestions? Thanks : )
