Thanks for the response. I am trying to find a place that will let me borrow or buy the correct tool, but I have not had a lot of luck locally. I might have to hold off on the work until I find it. Sad, I did my accessory belt less than two months ago and it was running perfectly. It still runs fine below 3k rpm, but I can feel the change above. I've saved all the pictures of the job I could find here, but if anyone has anymore data that you think would be helpful, please send them my way. Or just post here. My email is hak.tifosi@gmail.com

The bolt that holds the vibration damper in place is 24mm socket and needs to be replaced when you do the job. The specialist tool is pretty essential and you need breaker bars some times to get enough leverage. I also think the job is possible with the front end in service position provided you can get the car on a lift to work underneath it

Has anyone replaced the belt WITHOUT the T10069 tool? If so, what did you do/use?

Unless its a home made tool its pretty much impossible. Go to the dealer and ask to borrow the tool I had no issue. They would rather give you the tool than do something they have never done

Okay, thanks. Thats what I was afraid of.

I'm going to try this with lock carrier in the service position soon. There's been a vibration since my trip to B.C. a few months ago....

Wow... didn't know about this thread! I just had mine replaced as well; was getting a vibration at ~3k rpm... wasn't sure what it was, but turned out to be the harmonic balancer belt. I saw the old belt after the job was - it was completely smooth; not a single rib left on it!! That was at 145k km.

I would say regular replacement interval at 120k kms/80k miles is a good recommendation.

What sort of a vibration are we talking about here? Is this a "hmmm... maybe I lost a wheel weight?" vibration or a "holy poo I need to pull over!" vibration?

No, not like an out of balance wheel, which makes the whole car feel unstable (and that you can feel in the seat), but more of a steady, resonating shudder that you could feel through the shifter, throttle, and a bit through the steering wheel. Not at all "violent", but obvious enough that something wasn't right.

Failure is obviously not catastrophic, though I suppose if the belt snaps, it could get caught up and cause more serious damage than just the vibration associated with being out of phase. As mentioned, from the posts above, and my own recent experience, 120k kms/80k miles is a good change interval.
