    Hey guys,

    I started having some squealing noises from under the hood last year. I changed the belt and the noise went away. However it came back a few weeks ago. So I changed the tensioner and idler pulley's, but still it squeals sometimes..

    Any thoughts?

    Any video of it to better help narrow it down? Is it doing it only during certain temps or all operating temps? Does it go away at all during certain temps or remains constant?

    I know that the 2007 Tundra had drive belt and tensioner pulley noise issues and Toyota issued a TSB. My Tundra had the TSB done in 08 according to my records. A new , improved tensioner pulley and drive belt were used. I would think that you used new parts so they are probably up to snuff. Like Sean said, a good video with decent sound would help.

    It seems to make the noise at all temps, but sometimes there is no noise... Majority of the time the noise is there though. Wouldnt imagine it could be the belt again since i changed it last year..

    Any chance you can narrow down the location of the sequel? A little shot of WD-40 on the pulley may help locate the origin of the noise. But WD40 or any oil on the belt will not fix it. it could ruin it, you could try a little bar soap? This wont fix the problem just identify the source...
    You probably already know all this but... ;)Belts usually slip because they are worn out (but you said you changed it- rule that out), belt does not have the proper tension, or the pulley(s) the belt is moving over could be bad/going bad. Let us know what you find. Others will chime in as well.

    Also, if you didn't clean off the pulleys during the belt change.... next time use a clean rag with isopropyl alcohol and clean pulley grooves, get the crap off of them.

    Since I have already changed the pulleys I am going to try a different belt, maybe a gatorback like in the video above.
