Blonde female needs help....

no air con? .. not steering?...silverback

belts are staring towear screeching is probably the additional load from the alt on initial start up wd 40 is not going to help but will make you feel better that you are doing something . give the belt a bit of a tightn as after a while all pulleys get a wear mark in them and need adjusting

Sologirl, bring it around to my place and I will show you how to fix it.........................:-)

Tighten the belts ... and rub some soap over them to prevent squealing.

Without knowing more like how old the belts are etc it is a bit hard. Usually what you have described comes from the alternator belt which is slipping due to the initial load recharging the battery after starting. This is usually mostly done very quickly and the noise stops.

Tightening is typically all that is needed but sometimes if this has happened for a while or the belts are getting old they harden and get a glaze on them which has poor grip. I would tighten the alternator belt but do not over do it as this can cause other problems. If there is any sign of a glaze or hardening then replace.

If it is belts, that are worn or even dry this stuff is very good on them to help get a grip
The amount used means a tin is an investment. I think we have our second tin here that I have bought.

Thanks everyone!
I'll tighten the alternator just a tweak to see if it helps.

Do not spray WD40 on the belts..it will cause them to possibly slip and even worse break down and disintegrate.
The screeching is usually caused by belt rubber aging, loose belts or dry belts. I smear a bit of vaseline on the belts on my car to stop the annoying squeals that they make. Apart from replacing the belts it usually keeps them quiet until the next engine wash.

It could be not belt, but something else – dry water pump for example. Do you park your car in garage or outside? Is it happens ONLY in the morning? You can very easy test if it slippage of alternator belt due to extra charge – after coming back to home, shut motor and switch on all headlight. Wait 5-10 min and start car – if noise appears this is it, if not I recon it is something else. This sort of thing could be very annoying and difficult to track. I continuously use to have interim problem with belt noise in my LC. I have tried everything and could not fix either locate it. I have started remove belt one by one and figured out that aircon one responsible. I have tried soap, water and Belt Grip stuff without any speakable success. I personally recon that all this stuff is no more then cr@p and never fix anything, but just temporarily make it emit less noise – total boon for dodgy car dealers, but nothing more then that. Finally I have purchase new belt albeit old one was 6-9 month old. The same brand and the same part number. Problem COMPLITELLY disappears and I was not able to locate any tear and wear on removed belt. Total mystery.

I believe the most common cause of belt squeal on startup is the fan belt. Why you ask? Most vehicles have a thermofan and when the engine starts in the morning the fan is fully engaged, it takes 30 seconds to 2 minutes to disengage when cold, this is a hug load and makes a worn/loose/damaged belt squeal and slip easily. It could be the alternator, but most likely the fan. Please don't over tighten your belts and put unnecessary load on the alternator bearing and cause it to fail. If your belt is squealing and tightening it to the correct tension does not fix it then buy a new belt for it.

Solo it does sound like the belt but I dont agree with all the suggestions apart from twist it over by hand and see if the belt it starting to crack on the underside...ie check the condition.

If its still relatively new then do tighten it a touch , the longer you leave it the more it will glaze the pulleys and you will quickly wear into them.

Dont try the soap, beltgrip, wd40 etc...yes they all quieten a squeely belt but you still havent fixed the problem. The soap etc are good for isolating noisy belts for diagnosis but not for long term. Also make sure you only tighten it the recommended amount of deflection otherwise you load all the bearings and you will have early PSteer pump or Alt bearing failure.

Trust me been there done it all and learnt from it.

All the best

Matt.

Sound advice there Matt

Howdy there Solo girl, would you mind very much that if next time I need a huge response to my question, that I head it up with " blonde needs help"? Thanks in Advance!! & cheers

When the NRMA want to quickly tell whether it's a bearing or just a noisy/slipping belt causing the squealing, they use this secret diagnostic liquid - a jug of water.

Pour it on the belts when they're squealing - if it stops straight away, it's just the belt slipping or their surface has gone hard.
