Thread: Pulleys / Belt

  1. #1

    Default Pulleys / Belt

    I have been noticing this hissing noise coming from the pulleys recently and it's just doing my head in, it's louder as the revs rise.

    It's that noise that sounds like metal brushing against another bit of metal. I've taken it to Mazda and they said it's normal, meant to be like that blah blah.

    But when I first got the car it didn't make the noise. And other members on here have told me they don't have this noise.

    Was thinking about replacing them with aftermarket pulley kits... would there be any issues?

    eg. BOSCH DRIVE BELT PULLEY KIT MAZDA 6 L3 2.3 MPS TURBO | eBay

    Your local Mazda said that's normal? Take it somewhere else...

    Hey Fellas, drop around to my place and I will check it out for you. ( I should, but cant promise, be able to tell you the issue) May be bearings, may be old belts etc.. I have a couple of diagnostic techniques if you want.
    As for aftermarket stuff, I am unsure, but it cant help to see if they help, especially if they are lighter!

    serious? has it always been like that... i never heard it when i first got it.

    its annoying because when you drive pass other cars, or next to trees or a wall... you can hear it hissing.

    Certainly not normal, my car doesn't male that noise after 180K kms.

    Sounds like a Diesel. Lol

    Yeah mine has always made a bit of a hiss. I did think it was bearings or something but I dissmissed it and left it.

    I do wonder if yours is louder than others though. Would be good to compare on the next social meet for WA guys

    You live too far away from me, sorry! Haha, if I'm home and not busy I'd be happy to meet pretty much anytime to compare.

    Did you remember to turn off your interior light spud? Mine was dirty too, but at least my rims were black. And for those who don't know, my car got called a 'bubble' last night !

    I had the same problem too, Dealer said it was normal as they had another MPS in for a service on the same day.
    I said "well both the cars have worn idler bearings." They assured me it was normal.

    A few days later i removed both the idler and tensioner pulleys. Tensioner pulley was the culprit.
    Luckily its a metal pulley, so the bearing only can be replaced, $8.
    The idler pulley is made from plastic, so its a throw away. I replaced that with a metal version ($33) as a precaution and i can replace the bearing only if it ever fails.

    The next free moment i had i went back to the dealer, walked straight up to the service manger who served me. Cut straight in front of the customer he was attending to and slammed the bearing on the desk. He looked at me, i looked at the bearing, he looked at the bearing, i walked out.

    Hours later i received a call of apology.
    It was the most meaningless apology i have ever heard.

    Where did you get the replacements?

    Did the noise go away?

    What's the idler and tensioner pulley look like?? I want to check it out.

    GAHH I wish I had the cash to start my own workshop. I am not a qualified mechanic, but I know enough that I can learn more.. BUT I hate seeing issues with service departments.. they are all crooked i reckon. I would have shoved the bearing where the sun don't shine.. litterally, and called him a dumbarse. then told the MTA about it.. that woulda got you more than a blank appology!!!
    anyways.. good on you for atleast going in and shoving it in their face!!!

    My car makes the same 'hissing noise'. Drives me absolutely insane. Mazda also claims it is normal.

    Definitely seems to come from the pulley area. Need to find a trust worthy mechanic to diagnose it for me.

    Good on you, I so would have loved to be a fly on the wall. GOLD That's why I used Allstar Tuning to service my car because they are apprentices at dealerships nothing against them but my saftey comes first.... which includes my family.

    Hi Yodo,

    I have the same issue with my pulleys. The difference being though that my mechanic (a Mazda Specialist, NOT a dealer) diagoned it at my service yesterday. He is a great guy and the work they do is excellent. Not out to rip you off and he treats you car as if he is working on his own. Thats all a customer can ask for!!

    Anyway, i was wondering how tricky it was to replace these pulleys. Its not that i dont want my guy to do it but i just want to do it myself for something to do on a saturday! I did the pulleys on my Mrs' 99 corolla and i am thinking about doing it on the mighty MPS! Was it a real prick to do or was it pretty easy? Im pretty good wtrh the tools so thats no issue, im just wondering about bloody special tools etc!

    Cheers,

    Al.
