Timing belt change Carisma GDI

Hello all, I am Opel driver myself, but my ‘Father-in-law’ drives a Carisma GDI year 97. Now the 180 000km timing belt change is on this, and because I’m not completely untalented in terms of screwdriver technology, we want to change it ourselves, I’ve already changed timing belts with different cars, Vectra 2.0 8V, Polo GTI, last week at my Astra G OPC, was not a big deal. Now I started Google and read something about a hydraulic tensioner (ab with all the belts that I have changed so far it was so that a tension roller with pointer was there where you could adjust the voltage relatively simply. Unfortunately, there are no workshop books for the Mitsubishis. Does someone know what part of this hydraulic tensioner is etc. How about the high pressure pump, because the GDI is a direct injection, probably the high pressure pump is driven by the timing belt. The engine is the 1.8l GDI with 92kw (125hp) I’m grateful about tips and tricks We looked into the engine compartment before, space is in itself enough, only a servo line hangs bitsle doof in the way. Greetings, Martin
