I have a 02 4.6 4x4 and was wondering if it was normal to hear the fan clutch engaging/disengaging at idle after the motor has fully warmed up.. Its fairly loud when cold, and i understand thats normal..but i have never heard a fan clutch constantly engaging/disengaging as much as this one does..dealer says its normal.. any comments?

Hey Chris, my 97 does the same thing and went to a mechanic to ask him about it. He said it is normal for them to do it. Something with the computer constantly updating and adjusting itself for best performance

 

Nobody else?

 

sorry to hear about noise.

I replaced my fan clutch this morning on my 97 4.6.
i hear the fan real loud at start up but smooth out after a few miles.
i never heard the clutch before this.
