Worrying screeching noise

[Andyman]

Cars developed a very loud screeching noise from the drivers side of the engine from the duration of the ignition being turned.

its fine when its idling and up and running, its just when the cars firing up it makes a loud screech.

Anyone any ideas as to what it is??

thanx

Aux belt slipping

Aux belt slipping

Yeah sounds like it but its a sharp blast of a screech and only lasts till the cars sparked up.

The belts only done about 4k or so.

This wont be a pulley thats wearing out will it? Cant understand why all of a sudden its making a noise.

Crap weather at the mo so could this be a possible cause of it slipping?

Dont want the aux belt to come off and take the cam belt with it thus the engine

Test it by before you start the car, spray some WD40 on the belt, then turn it over like normal, and see if it stops the noise

Mine has also developed this noise ive just had the aux belt done , its going in on the 6th to get it sorted !

Il try squirting WD40 on it first and try that.

Main concern iv got is if one of the pulleys is wearing out or cracked

Possible undertensioned belt ?

Its been ok the 4k+ ive clocked up on the new belt plus its only on initial starting up.

Roads up here are like a river just now with all this rain so not sure if this will have anything to do with it
