Where did you get this info from? They don't have particle filters.
Generic coolant is fine, nothing special required unlike the newer commonrails.
Brake fluid again, normal grade is fine. Dot 4 etc.
Fuel filter is located in a black housing at the front of the block (obviously under the cover). The lids are on tight and turn anticlockwise to gain access into.
All HDIs are self bleeding. So once the filter is replaced, simply start the ignition a few times in a row (without actually starting the engine) and itll bleed itself. I'd say 10 times and then crank her up.
