    Hello group,

    I have a small tensioner pulley issue on my '99 SL1. I started the car the
    other day and the battery idiot light was sort of flickering, so I thought
    "damn it, there's that infamous alternator replacement", but upon further
    inspection under the hood I noticed that the belt can be taken off by hand.
    I drove it home this way and it made it fine, but I'm wondering what the
    replacement is going to be like. Anybody else have this happen to them? I
    replaced the belt last summer at around 65,000 miles.

  2. Either the idler pulley came off, or, more likely, the tensioner 'blew
    up' (no, that's NOT the technical term :)

    If the idler pulley is on, then replace the tensioner. You remove the
    wheel, cover thingie, and get at it from the side.

    You need a 10 mm socket (1/4 drive, and a few extensions), and a 10mm
    box wrench helps too. Oh yeah, you need some other size that I can't
    remember off hand now.

    Remove the pulley with that other size wrench (box wrench), then use the
    10mm to remove two bolts and oput comes the tensioner. Put the new one
    back, then the pullley, then wrestle the belt back on :)

    Have fun! :)

    just had mine replaced about two hours ago. It is a little better than an
    hours work, $200 for the tensioner.
    I got a used one and had it installed for $110.

    I picked up a tensioner at NAPA for around $60. Took about an hour to complete
    in my driveway. James

  5. I also bought the NAPA one, I remember it being more like $80.

    AutoZone rents a special tool that helps to hold the tensioner back while
    you slip the belt on. I did not use it, I just used raw muscle power.

    Napa has many different prices for the same part. It depends on your account.
    I bought it through my company and we get a deep discount because of the
    quanity of parts we buy for our fleet.

    Its easy. I changed mine in a parking lot once in about a half hours time with
    limited tools. Best bet is to take pass tire and wheelwells off and get it from

    On another note, you're lucky you didn't hurt the motor if the water pump
    wasn't spinning......

    The plastic one I bought only lasted 6 months. I would recommend getting a
    saturn part or another brand made of metal. Also you can lower the engine
    slightly by loosing the top engine mount. Makes the job a whole lot easier.
    You will need a special tool.

    The plastic one I've got has lasted 2 years. If you wanted to you could just
    put the old metal pulley on the new tensioner.

    Why would you need some type of special tool? I didn't!

    Sorry but as a matter of principal, I would not install a plastic one unless it
    was the last one on earth!
