    Strange whirring noise coming from 1.6 16v

    I have recently noticed a high pitched whirring noise coming from around the engine bay (drivers side). The higher the revs, the more high pitched the noise goes. It seems to happen wether the engine is cold or warmed up. Any ideas what it could be (I have attached a sound clip you may need to turn the volume up quite a bit).

    Thanks

    If the noise has started since having the cambelt fitted then i would take it back to whoever did the job, as said it could be too tight and may require loosening off a tad
    Try removing the drive belt and running the engine without it and see if the noise has gone, if so you know that it is coming from something driven by the drive belt ( alternator, air-con, tensioner pulley etc )
    If the noise is still there with the drive belt off then you will know it's coming from the cambelt area

    I'm not too sure wether it was at ther time of the cambelt or slightly after when I had the air con repaired. I think it was during the air con. Could the drive belt be on too tight? The guy who did it said that he only replaced the pressure switch so im not soo sure. The noise happens regardless of wether the air con is on.

    Sounds very much the same as the noise I had from mine, in the end the garage narrowed it down to the alternator. Upon replacement the noise vanished. Hope this helps Vinnie01 Astra G 1.6 16v C.D

    Could make sense, with the air con and everything. The only thing being is that the noise is there even when the a/c is off. Any ideas on how much I would be looking for a new alternator and fitting? Also how difficult is it to take off the aux belt?

    Easier if you remove your airbox, 15mm spanner on the drive belt tensioner, remove the belt and try running it, if noise gone you know it's something driven by the drive belt

    I removed the drive belt and the sound was still there. So I think it probably is the fact that the cam belt is on too tight. I shall give a stealer a call today and see what they can do.
