    Hey guys, new to the forum. just got a 2003 v6 manual sr5 tacoma with 80k miles. I have noticed a light squeal from the engine area (which I am assuming is a belt) when I start the car and it is idle. I don't hear the noise as I accelerate 1st through 3rd (possibly because the engine is louder than it) but I do notice the squeal gets louder when I am accelerating in 4th and 5th gear. I am nervous about the noise coming from the timing belt which i know should be replaced at 90k and can cause major damage if the engine fails. But I am hoping it is a different belt that is easier to replace and much less costly.

    Thanks for the help

    Use the search button in the blue bar - there's lots of posts out there about this already.

    Check your belts for proper tightness - find an area of each belt that is OPEN. Grab the edges with your thumb & finger and twist. If the belt goes past PERPENDICULAR, the belt is too loose & needs tightened.

    Also, inspect your belts for wear and inspect the pulleys for anything obvious.

    If that doesn't help - do another search.

    I did try to search but must not have been using the correct terms because i was coming up with no results based on squealing that gets louder during acceleration. Thanks for the tips though!

    clicked on the links and they didn't take me anywhere. i was able to just search for 'belt' and find some good info. haven't had the chance to check the belts yet but i did notice this morning that the noise wasn't there. it rained last night and things are wet so maybe that is stopping it from squealing.

    Thanks for the help, now i just have to figure which one it is and how to change it!

    Moisture isn't necessarily going to fix the problem. As soon as things dry-up, the squeel will most likely come back.

    It won't necessarily be a belt. You have to check the belts to make sure they're tight. If they're already tight enough, then you've elminated that out of the equation. If they're loose - get them adjusted properly and go from there.

    A squeeling could also be a bearing going bad in any of the pulleys. In paticular, the A/C idler bearings are the first to go usually.
