ZKD-Tausch. Questions about questions

Hya, after the old clothes collection it was so far today. The ZKD-Tausch at the Omi could start. At 22:00 at work. Is everything very different from my old BMWs. First I broke the cover of the timing belt 🙁 Was somehow too brittle the thing. Now I can watch where I get something like this. And then I have to ask myself a lot of questions: 1.) Do I have to dismantle the cracker, or do I get the up with it when I separate it from the exhaust? 2.) Are from h Inten still parts which have to be taken off before 3.) on the lashing machine is a bolt on which a mother sits with fuse and holds a holder (because of which the cover broke. The mother does not open, however, because the bolt turns with. Do I come up there later when the head is down to fix that? 4.) How the hell do I get, if it has to be, down the driver’s neck? -> What does everything have to be dismantled? 5.) Does the air conditioning pipe have to be lowered? Thx Mathias
