With the manual tranny you can just put it in gear and apply the brake, which is the method I used for the first belt change on my '05. But as the second belt change was approaching, I had my daughter's '06 automatic that was also coming due. So I looked around for some other method. Guys talk about removing the bolt with an impact tool, and they also must reinstall it the same way, but that's not for me. There is specific torque spec for the bolt, and I suspect it's there for a reason. If the FSM said "gun it off and gun it back on", I would have done it that way. For the guys who always do it this way, hey whatever floats your boat.

So in looking around for something else, I saw this thread from snrusnak.

I was thinking about going this way, but started feeling uneasy about it. My daughter lives 900 miles away, and Murphy's law says that if something bad can happen, it will be when I'm away from my workbench and all the rest of my tools. I kept thinking about how nice and easy it was to remove the bolt on my other daughter's Honda Civic. The method Honda uses with the Pulley removal tool is IMO by far the best way to design this job. So I decided to experiment with trying to adapt that for the Aveos. Those results are described in this thread.

I did this the first time on my '05 with the security of being home, and then took the stuff on the road trip and did her '06 using the same setup. I'm not trying to push this on anyone, but will say that I'm really pleased with the way this all worked out. I fumbled around a bit trying to get it to work the first time, but in the end it functioned perfectly 4 times - 2 removals and 2 installs. So I can say for certain that it does work, even though it might sound like a hairball idea.
Now all of that said, you can probably do what snrusnak did and have it work out fine. Good luck, whichever way you go!
