    I have been chasing a whine and thought it was the tensioner pulley. I had two mechs check it out one said he couldn't figure it out the other said it's probably the tensioner pulley. I think it its the aircon compressor. The noise seems to be worst down low and from what I can tell is noisiest from the front of the engine.
    Question is why would an aircon compressor make a whine? It will be a $1000 job to have it replaced. Wondering if there is anything I can do myself or a mech can do cheaper than fitting a new unit.

    Mine has held gas for 18 months and its still nice and cold on a 38deg day. Rather than a regas i will see about getting the bearing replaced. I looked online for VP-VR compressors and they are between 500 and 600 bucks.

    Thousands of em at the wreckers..just get one that hasnt been open to air for weeks or mths ....to work out the whine get the shorter serpentine belt and by-pass aircon....Ive been doing that for years over winter to get the extra 1/10th HP to get out of the way of skidding P platers ;)
    never done the bearing change as heard it can be a pig...

    The VP thread linked makes it look fairly straight forward. A regas is 150 bucks. At a guess for 220 bucks i can have the bearing replaced by the aircond tech near work. Be 100 bucks down here for a compressor with no guarantee it hasn't been on there for 25 years and have the same problems within a few months mine has.

    bloody hell you pay a lot for regas, the bloke I use only charges between 75 and 90$ ...then again he was doing it every 2mths before it got fixed :) prob put his first born through collage...Check the 2nd hand compressor for discoloring from oil leaks and any wrecker worth his ??? salt (never understood what that meant) will plug the gas hose holes with something....its just the oil in em is hyperbolic and sucks up moisture

    you need aircon down here in the winter. The heater alone is not enough to stop the windows fogging up when its minus 10deg. The aircon drys the air in the cab.

    The aircon also unfreezes a windscreen in around 6-7 mins. The demister on its own can take 20.

    Hi Losh,

    The VS that belongs to my son that I've been working on for a month now has the exact same symptoms as yours. It whines down low and not up high. I too was thinking of obtaining another unit from U-pull-it but with that you just don't know what you're really getting as you could just end up with another bag of issues and then the extra cost of re-gassing. All this Ozone depleting legislation has just driven the prices up through the roof.

    I'm going to do the front bearing replacement myself and we'll then see if that solves it.

    Sorry but I just can't justify buying a brand new compressor for a $300 vehicle, well that's what I paid for it off some non intelligent owner that told me it had a blown diff when it was a seized RH rear brake caliper that had a 5mm thick rotor being gouged unmercifully by a pad backing plate.

    Yeah like yours under load it quitens down. Also less noise with aircon running. Im considering trying to do the job myself. Thing that's stopping me is having my main tools, press etc 130km away from where i mostly live now. Plus the city is over an hr away and hard to get too if i don't have transport.

    Whine is usually the alternator on those. Location of sound can be difficult to pinpoint. Does it get louder if you turn headlights/accessories on?

    No it gets quieter. Any load on the engine lessens the noise. I thought it was alt bearing but it is smooth as.

    My thinking is, if l don't fix it, whats it going to cost me for another car? And what is going to be wrong with it, & what is it going to cost me to fix it.
    The day you buy it everything seems okay. After a week everything seems to break.

    Can't speak for the VS but the VR compressors are pretty good and they last a long time. $50 bearing verses $600 for a new compressor plus $250 for a regas and accumulator, I know what option I'm taking. I'm with VS-Lover just repair what's there before forking out the big money.

    How is that? Accumulator is around $100 and regas is $150 in Launceston. In Adelaide 12 years ago I was paying $120 plus parts.

    A lot of small car related business have done the aircon course and run a small regas setup out the back ;) lots of ppl doing it makes for cost reductions...
    drive around and you will see the signs for 90$ regas 2 streets down $80 and so forth....average price is around $90 pay more and your getting ripped off..
