I have this chirping noise under the hood. I did replace the belt, idler and tensioner/pully and it still chirps. More so when its getting colder as it is and chirping more. Does anyone know how to stop it.??

Check the pulleys for nicks/burrs on the 'teeth' of the pulley

i have noticed this same thing drives me crazy, I'm thinking its the water pump bearings i noticed that when i was spinning the pulley by hand when changing the idler and tensioner pulleys that the water pump pulley made a very subtle chirp sound. so that's where I'm at now, may have to bite the bullet and bring it in and see if this can be taken care of.

Waterpump or Idler are the usual culprits. Ive had an alternator in the way past do it, but it was also just as it seized up.

My truck did this early on. Turned out to be the water pump.

UPDATE: dropped off my truck yesterday to the dealer and they called saying that it is the water pump and he also told me that looking in the Chrysler computer system he told me that it is a common problem with the HEMI water pumps depending on the year I'm sure, he also said that he would have to order one for me and they were on backorder, luckily my truck is still covered under my powertrain warranty so it will be taken care of when he receives the new water pump. just giving you the heads up if its chirping exactly like mine is.
