Hi RedArrow,
Thanks a lot for your explanations. I've the "revue technique automobile" (in french), which is a shop handbook for official services in France. Is not very explicit about procedures for a non professional like me. But it has all the torque specifications.
For replacing the timing belt, I used also the YT tutorials of Michaelovitch:

These D24 volvo's are very rare here and the TDIC versions even more. This SW was imported by myself and honestly I don't know anyone who has the right tools to get the job done. So I decided to do all the maintenance by myself, because no one is going to buy tools to service only my car. If they try to improvise, it's going to be a bad job. I've also an old beetle and for this car there is a lot of competent people that can fix it, because it was here a very popular car. I've other old cars on different stages of conservation but the only one I repair by my hands is this volvo. I like so much this SW to risk an improper repair. I promise, I'lll search photos of my trip to Patagonia in this volvo in 2013, which was also my tent
Those photos must be sleeping somewhere on some hard drive...
All the best for you!
