screeching aux belt

[Guy]

just a quicky... screech from aux belt upon startup for about 10 seconds.. once its got some heat in it then it goes away and doesn't return until the engine is started up again

too loose? too tight?

it has been replaced not that many miles ago but ages wise I guess it is coming up for two years.

Could be either or. Did you change the tensioner when you changed the belt ? Had this on mine but I can't remember if it stopped on startup or not. I thought it was the belt but tightened that and it still happened so replaced the tensioner as the bearings were dry.

Tensioner?... has this car got PAS then?

I didn't think it had any tensioners... the 'pulley' that the belt sits in on the end of the alternator wasn't replaced... but I thought the belt was tensioned by adjusting the bolt on the alternator and moving it backwards and forwards?

nope... no PAS

Nope, no tensioner...

how much does the belt twist when static?... should only be a little amount of play.. screeching normally means loose so you may have to loosen the alternator and tension the belt a bit more.

Oh.. you sure its screeching?...

May need slacking off a bit..  Myself and Rich had similar issues with a high pitched whining noise which turned out to be the belt being too tight...

Slacken it off ever so slightly and see how it is then.

well for about 10 seconds it sounds like a cat having its balls trapped in a door... then it goes away!
