It depends on whether your are torquing head bolts, wheel bolts, spark plugs, or something else. They all have different torque specs.

front ones remove wire clip remove bolts from caliper hang caliper out of way remove pads remove 2 bolts from pad carrier put to one side remove 2 disc retaining bolts remove disc may need hammer clean hub flange with wire brush fit new disc clean pad carrier and refit fit new pads put some copper grease on back of pads push in caliper piston slowly using large grips or g clamp fit and secure caliper pump up brake pedal check brake fluid level do other side for rear brakes see my solutions

when your remove the timing belt cover off the front of the engine the plastic part that stays bolted to the top of the engine has one slot over each cam between the 12 O'Clock and One O'clock position . hope this helps I could send a pic but it would be tomorrow

if this helps.. I had the 1998 model S70. the water pump was driven by the timing belt. you had to take the timing belt off just to replace the water pump. it was just a simple bolt on replacement. the only difficult issue is resetting the hydraulic tensioner on the timing belt. the hydraulic tensioner has to be completely taken off and compressed VERY SLOWLY in a vise. then insert a very hard drill bit or (special volvo tool) into a keeper hole, reinstall hydraulic tensioner onto car and reinstall timing belt.very quickly remove drill bit from keeper hole in tensioner and the tensioner snaps back out to put tension on belt. and you are done.

take front bumper off 4 bolts in front center screws and clips in wheel wells replace headlight assebly about $193.
