Noisy fan belt....

Usually its the power steering belt loose that causes that Tighten it up a bit or replace it if its old

Belt squeal on startup is often the alternator belt. Starting drains some powere from the battery and the alternator works harder for a short while trying to recharge it. Could simply need adjusting up a bit, or it could be the belt is worn or glazed. Don't use lubricant - it won't work and will probably make it worse and/or damage the belt.

Hi Rowen
Belt needs adjustment. If is glazed it would ALWAYS squeal and more you accelerate, more noisier it would be.

Fan couplings are quite tight cold plus the belt softens with heat. Its probably quite old and hard first thing in morn, particularly if yr in S states.....silverback

Rowen, Easy fix is don't believe the other advise. Tighten if more than an inch of play in the belt and spit on a bar of soap and apply the bar to the belt whilst it is rotating (carefully) and this should stop the squawk. Otherwise it could be number of potentials, ie. alternator bearings, water pump or air con.

There are a number of things that could cause belt squeal.

1) Loose belts.
2) Worn belt causing the belt to bottom out in the pulley.
3) Worn pulley causing the belt to bottom out in the pulley.
4) Glazed belt.
5) Damaged belt.

If the belts are over 3 years it may pay to replace them.

Or remove all the belts and check each belt for damage, bend the belt in the opposite directing and see if it cracks.

Check to see if there are no cracks in the belt.

Check all the pulleys to see that the belt has been running on the sides of the "V" and not bottoming out.

Check to see if the right section belt has been fitted to suit the pulleys.

Spin all the pulleys that can be turned by hand and check for excessive play and notchiness.

Check to see if all the auxiliary are tight like alternator, power steering etc.

Be warned sometimes tightening a belt can cause the belt to break if you don't check it for damage first.

Try and stay away from soap or belt conditioners as it is only a short term fix and you may be covering up a underlying problem that may make you strandard.

Hi Ro, Talk about discrimination. "Solo girl " put in a very similar post as yours about two weeks ago. In a very short space of time it generated 1300 odd hits, and more replies & follow ups than you could poke a stick at & LOL
I am not sure if she got her squeaky belt fixed or not, but she certainly got plenty of advise!! Anyway, hope you get your problem fixed. Cheers.

I was very surprised a couple of years back as to how tight they need to be - the belt may be fine but just needs to be really tightly tensioned.

If you just have a noisy fan belt, eg not slipping. A spray with silicone spray works for quite a few weeks. Theres also Armour all but that doesn't last as long.
