    Noisey AUX belt

    Vauxhall just replaced the aux belt and a pully during the cars service, when you first start the thing up from cold it sounds like crickets!! reminds me of the sound youd expect from a clapped out motor..... goes away once warmed up.

    is there adjustment on the belt at all or do you think this will go away as it beds in?

    cheers rich.

    jeeeeeeez we were just talkin about u yesterday

    was it making the noise before? I know the tensioner often makes a noise - particularly on startup.

    if u whip off the wheel u can get access to the tensioner ur self - just check its actually secure

    or

    take the fecker back and get the useless feckers to sort it out

    No adjustment btw - the tensioner is there for the sole purpose of taking up the tension etc

    was it the actual tensioner itself they replaced? have u got the paperwork there with any details etc

    how do mate! think ill just get them to have a look at it tbh, spray a bit wd40 on the belt and it disapears but it hasnt backed of in the week or so its been fitted.

    had a bit of a mare with repairs in the last month or so, to list a few....

    service
    timing belt
    aux belt
    water pump
    exhaust front middle back
    brake lines front and back
    mot

    now theres a dirty crack in the manifold and a strange high pitch sound from the new front section of the exhaust so hoping its just the manifold....
    Cheers Rich.

    I'm having the same problem as well. I have an opel astra x14xe and a week ago i changed the tentioner and belt, because it was ticking. But now, especially when it is cold i have another noise different than the previous one. It sounds like the exaust is rattling. The engine didn't make this noise before the change of the tensioner. But it did make it, some years before, when i had to replace the tensioner again to make it go away.
    This rattling noise is produced when the rpm is low, around idle, and i'm manouvering for parking etc. I don't know what to do. The sure thing is that i'll go to garage again to get it looked at. I'm a bit suspicious about the pulley of the alternator, but i'm surprised that this noise, one day before the change of the tensioner was absent.

    (I'm fed up with the quality of the parts GM makes.... and they aren't cheap at all! 150€ for just a tentioner!)

    I had a similar problem with my Zafira GSi, I changed the aux belt thinking it was this....

    bet you'll never guess what it was...

    a bolt had snapped off in the head from the front manifold...had to get it tapped and resecured, good job a good mechanic m8 did it cheap else it would have cost me a fair bit!

    Yours probably is as the belt as youve just changed it. Try spraying with WD40 or maintenance oil on startup to see if the noise goes away just to be sure.

    when u change to a new belt tension-er the spring is stronger then the old one so puts extra pressure on alternator axle and you get a wining noise from the bearings or a squeak when cold

    In my case the sound isn't like wining or squeaking.
    It is a metal sound and it sounds like as if the belt is loose and the tensioner goes all the way up to it's stop position. The mechanic didn't tighten it up with the apropriate torque. Do you think that this could be causing the noise?

    find out if you have auto tensioner or manual first?

    My Zafira GSi has an auto tensioner, not sure about your model though.
