My cambelt was done along with water pump and alternator by last owner have recipet and the parts are shiney why they didn't do aux belt baffles meI can't remember it being hard, but I have a tool for everything and a decent jack..
The tensioner needed the jubilee clamping trick, but other than that it was a breeze. I had the car stripped for the cambelt so I'm unsure about how little could be removed.
I'm sure that's where I rested the lever bar onto and put some weight on it while I put the bolt...What a nightmare had to give up at 6pm struggling to get tensioner on even with clip just kept jumping off
