Timing belt change at Escort 1.6l 16V 90PS

Hello, my Escort BJ 95 has now run 63000. Therefore the timing belt should be changed. The workshop at my place around the corner would like 150 euros for this! I had already bought the flat web belt and the timing belt myself (just 50 euros). Since I have always done everything myself on the VW, Kadett and Audi 80 (coupling, Bremen, timing belt, water pump), I would like to venture up to the 16V. Can someone tell me what I should bear in mind! Where are the make-up on the gears? How will the Za hnbelt tensioned? (water pump, extra tensioner?, special key required?) Thank you, Gruss Bernd
