Squeaking Engine Noise At Idle

[tomsawyer]

Hopefully you guys can help me out with this. I have an 05 4.4 w/ 51k.

When the temp is cold outside, I'm talking about 60 or less, I get a loud squeaking engine noise at idle. When I press the gas and the rpms go up, the noise goes away. As soon as I take my foot off the gas and the engine comes back down to idle, I get the squeaking noise. I have attached the thread that deals with this in the 3.0 engine and it seams to be the intake runners but no one has addressed this on the 4.4 and I'm not sure if that part is on the 8 cyl engine. Can anyone advise me as to what is causing the noise on the 4.4. I have included the link for reference for the 3.0 engine.

thanks to all who answer.

you sure its not one of the belt tensionors or pullies.

I had it, idle tensioner pulley. Got it fixed. Not expensive.

please do this before u consider repairs ...power steering reservoir is above the tensioner pulley and it has a stock clamp on the hose that has a tendency to leak i replaced the belts replaced the pulley replaced pulley wheels....i would drive around next day the noise came back i was really frustrated so i took the tensioner off and cleaned it out with soap and water and put it back, replace power steering reservoir put new clamps on it put new fluids and was good to go i bet i would not have to spend all that money if only i would clean up my belt tensioner that was originally there u might just have to clean and lube the spring inside the old tensioner buy the tool to take the fan belt off on ebay that's where i get my parts so far have not been disappointed with my purchases, also thats where i got my power steering reservouar super cheap. good luck with your project
