I tried to upload a pic of the IPD product.

I just watched a video at IPD about the different holding tools they sell.

I am puzzled by what the tech says a :59sec.
He implys that the basic holding tool wont work with the variable valve timing.

Why not?

I don't have a Volvo with the VVT or variable valve timing. Thought I read that you had to counter rotate engine to release spring pressure, don't quote me, I would think that info is here or on volvospeed or Matthews sites.

For marking the belt to the cam, I always use white out or even a dab of touch up paint to mark the existing belt to the cam and crank pulleys (and any others that you care about). Once the belt is off, transfer the marks to the new belt by counting teeth (several times), then slip new belt on to match marks on the sprockets. Sure fire way to get it right, first time, every time, worked beautifully on the 850, my Golf, etc. Wish I could say I thought of it on my own. Good luck. Mike

Once you get into the timing cover and have the marks lined up, take the time to make yourself a camshaft sprocket holder. I forget the size of stock that you need to start with, but it can be made out of 1/8" flat stock and bolts to the top of the head. Alternatively, count (and write down) the number of teeth on the belt between the timing marks.

If you don't separate the cam sprockets from the cams, you can disregard all of the VVT mumble-jumble. Note the car in this video has VVT on the intake cam but it is of no concern to the tech.

Surprise, the 2004 probably has CVVT, both cams.
