Quick automotive question

[KMK0420]

05 Chevy TB..

lately, i've been hearing a loud, high-pitched squeal coming from under the hood. checked, it's either the belt that passes over the alternator (?), or the serpentine belt. now, weird part is, after the trucks been on for awhile, the sound fades away. most noticable on warm, dry days. cold or wet days - the squeal isnt there?

what does the sound like? i doubt its just tension. my luck i'll have to replace whatever belts making the noise..

you want to make sure it's not a bearing if possible, otherwise
go to the local automotive store and buy a can of belt dressing.......

i heard any lubricants on the belts are no-no's..
but thanks tho! will pick up a bottle..

is it better to use this and wait for other problems if they arise, or just get the belt replaced?

just replace the belts if it is squeeling.

prolly alternator...they like to squeal on their way out...easy to have it checked tho...replace the serp. belt while your at it...also very easy.

Just change the belt.... Belt changing's gotta be one of the easiest things to do. Also if its light outside you should be able to see the belts condition fairly easily... does it look greasy or grimey? If so it needs replaced.

Yeah, belt is either loose or worn-- Try tightening it, or just get a new one--
Belt dressing is not a lubricant...it is actually a li'l sticky...but that is only a band-aid....best to fix the prob--

My vote from experience would be to tighten and/or replace the drive belts(fan, alternator, A/C, etc).

get that shit changed before your battery starts diein

yeah i have a high output alternator on my vehicle, it's less than a year old so i know its not the alternator. a yellow top batt under the hood also..

what does a shop normally run to replace a belt? cost + labor?

edit: getting it replaced friday more than likely..

my car has 1 belt for the alternator, the serpentine belt, runs $50-75, labor dude said $20.
