Thanx for the replies guys,
Where do you place the stethoscope on a running engine to isolate fan clutch noise. The "real estate" between fan clutch and water pump seems so close. Doesn't the noises of one or the other transfer through the metal of the engine. I am already aware I should change it if it is bad. Just trying to figure out if it is bad (thus my original question). I have already installed tensioner pulley, idler pulley, and alternator (correctly) so I have already ruled out these items. Again, thanks for your input........
