2000 Ford Explorer XLS Chirping/Squealing noise

--------------------------------------------------------------------------------

I need help! I have a 2000 Ford Explorer XLS 4.0 V6 OHV, VIN-X. I started hearing a Chirping/Squealing noise last week when I started my truck but went away after about a minute and then it came and went. I replaced the Serpentine belt, Belt Tensioner, Idler Pulley, Water Pump and Fan Clutch and the Alternator, and the Chirping/Squealing is still there. It is loud at startup if the truck sits overnight but goes away after a minute I hear it while driving ever now and then and when it is in park also, its not so bad if i drive it more than a half hour but it is still there. I took it to a Ford Dealership and they have no idea but they said it is defenitly a external noise. Does anyone have any ideas what it could be?

Thanks.....Tony

It could be your cam position sensor causing the
chirping. If the sound resonance is about 1/2 of
the engine rpm, then that would tend to confirm it.

The sensor is located to the rear of the intake manifold,
partially hidden by the coil pack. Do a search on here
for more information on how to chang it.
Good luck and welcome to the forum......

Did your cam position sensor replacement work? Have replaced all including a/c and after a/c replacement the squeek went away for about 3 weeks and then returned.
