Noisy belt...?

I have just has the fan/alternator belt changed on my car but it keeps making a squeeky noise (it has mainly stopped though).



Any idea's on how to get rid of it? some people say WD-40........
Noisy belt...?
does it tend to get louder and more persistent when it rains?



i had a belt that was absolutely obnoxious when it got wet, and i ended up putting corn starch on it to dry it out. weird. but it worked.



i have no idea if this would work for you, but if it gets irritating enough, you might try anything.

Under no circumstances put WD40 on it.



You have either got a belt that is too loose, or there is a problem with one of the bearings being driven by the belt.



I would suggest you take it back to who ever changed it and get them to check it out for you
Check for tension first, approx 45 degree of twist. if it is set right with the engine running hold a candle to the working edge, regular cheep white candle not lit, the wax will rub onto the belt and stop the noise, repeat when required. sounds odd but it does work.
Hello, Get a good make furniture polish Like Mr Sheen (if I am allowed to say, I am sure I will get shot if not) Mr Sheen has silicone in it, spray this on your belt, this will stop it, you may need to do it again at some point.

Good luck
your local auto store has a thing called belt dressing, it softens and smooths the sounds of belts. WD40 is not the answer as it is an oil and oil is bad for belts ! It will deteroritite them! Check your belts and hoses for wear every 3500 miles when you change your oil! please ask any questions. I will answer to the best of my ability (I Do Not Work At An Automivive Store!!!) (I will not give you a place to buy!)
Its not tight enough, after a while it stretches a bit so it starts to slip and squeal
its the exhaust, u need to get a new one
put talcum powder on it. Just a little bit not a lot. then it will be quiet. it's just slipping a bit
|Take it back to the garage that put it on, they haven't put it on properly. Any repairs if you aren't happy are best dealt with by them you may well make it worse
oil it
sounds like the belt isnt tight enough



id bring it back
It's either too loose or too tight! Or maybe even the wrong belt has been fitted. When does it squeak, when you rev up (loose and slipping) or all the time (tight or wrong size)



Are you sure its the belt making the noise and not the alternator or water pump bearings?



You dont say model/ year of car !!!!
I have to admit that I go with the repair or replace crowd. If it is the belt then the use of a lubricant (which is what the WD40 is) might give you a temporary fix but it will not be a solution. First check the wear and tension on the belt . Then work your way through the other 'can be wrongs' until you eliminate the possibles and find the real culprit. Just start with the simple (read easy) and work through the list. But get a manual for the car (check the library if you don't want to buy one yet) even if you are not going to ever take the do-it-yourself route. If you have at least a basic understanding of the vehicle in its' possible problems and repairs it will save you a lot of time, money and frustration when you do need something done.
