I don't think this is such a bad way of doing it as the new and old belts will have the same number teeth, so you can be sure you've got them in the right place. Obviously, the new belt will be tighter, so from there it should be relatively easy to back it off until the 90 deg twist method applies (or until it stops whining

).

I'd be interested on peoples thourghts , i've always thourght that belts whine when they are generally too tight, mine whine a bit, which doesn't sound too good when sitting at the traffic lights, is there anything i can do to shut them up ??

On the 968, the cam belt has a spring loaded tensioner, but the balance shaft belts need to be tensioned manually. I have been told that as long the the balance belt can be hearding "singing" a little, the tension is fine.

The belts always whine a little, they seem to be worse when new & normally quieten a little after 2-3K miles.
