Front engine noise

[jeedee]

It's the common dilemma: Noise from either the fan belt, idler pulley, pulley alignment, cam sensor, tensioner....et al. Would the fact that the noise in my 3.0L occurs ONLY when idling...and that increasing the RPM by 100 or less, stops the noise...help narrow down the possible cause of the noise...? (Sounds like a fan belt to me, but belt is perfect....no cracks, etc.) Any input appreciated.....Charlie.

take a bottle of water and spray one of the pulleys a once or twice. the belt doesn't need to have any cracks in it. my little 3.0 belt looked and felt just fine but was the problem to my noise also it had 225k on it and was the factory belt

Thank you, Karu 89. Wow....225 miles on a factory belt. Why we love Fords.

Take the belt off and turn it around so it runs the other way. If the belt is the noise it will probably go away.

If I get to the belt-removal stage, I'll replace everything...idler, cam sensor, tensioner.....etc. Thanx for the reply.
