Questions about the cylinder head seal change at the Matiz

Hello, background / motivations etc. (so you can safely skip) my wife’s matiz has been slowly consuming water for half a year. Since we don’t want to drive the car for long and I didn’t expect it to be problematic quickly, I tolerated it. Now on the way from work the engine control light has started and for a short time he probably also indicated that the engine temperature is too high. I already thought that but still wanted to get an opinion and price from the mechanic and I filled up his coolant container again the next day and left it to drive about 500m to the workshop. He jumped a bit reluctantly, squirted white and embroidered. I was already 90% sure that it is the ZKD. This confirmed also the mechanic. The cost should amount to at least 350€, which I personally find amazing little for the work. But denno The 350 is the lower floor of the price range. Since I have already done a lot of manual work on the car, I have decided to do it myself now. I have never changed a ZKD and therefore stand there a bit awe-inspiringly and do not want to do anything wrong the first time. Since I was afraid that the screws on the exhaust are so rusty that I can’t get them off, I have the Amit first started to solve all of them. I also managed to get the screw from the bottom left, except for the screw that sits above the oil filter. I think if I unscrew the oil filter, I can get the screw from the bottom better. So I already drained the oil now. It came out first about 250ml of water. So ZKD is 100% leaky.From here I need help Now I wanted to order a cylinder head seal kit via daparto am on a set of Blue Print ADG0629 4, which is delivered by Autoteile-Devil. However, with Autoteile-Devil it is not shown to me as suitable for our Matiz, only for M100 and M150. So I am on the Plueprint homepage and there it is shown for M2 (M200?) only for B10S, B10S1, LQ4. But I have no idea which engine we have. I know that it is 1.0L, 4 cylinders with 67Ps. How can I find out which engine code is installed with us and whether the seal is suitable? Instructions for changing the cylinder head. For whole sets – which I looked at – there are no cylinder head screws included. But that doesn’t mean that they are not stretch screws and that need to be replaced. Do I also need new screws?How do you leave off the cooling water on the skilfully without messing up the whole parking lot? The Matiz has no drain tap. Is it actually enough if I leave the cooling liquid at the small cooling circuit? So if I use the connection e (See ang Depending image of the cooling circuit; source: autocats.ws) drain? I want to build everything apart next, so that I only have to assemble it immediately after delivery of the parts. Do I actually have to dismantle the two wheels for alternator and climate to see the marking on the crankshaft? Can one somehow avoid the more work? In the train I also wanted to replace the oil force, because the old one is rusty and it is already last time at the TÜV as a note Since the exhaust goes directly under the oil face, I wonder if I can get the tub out there without disassemblying the exhaust. Does anyone have any experience? I will certainly have further questions. These are the ones that are currently most of my concern. Thanks in advance for the answers.
