I've done my '99 S70 T5 timing belt twice now - first time belt only and last time belt, waterpump, idler and tensioner.

Belt only took around 45 minutes and was a doddle. To do the lot took an hour and a half and really wasn't difficult either.

The timing marks are pretty near impossible to see so what I do is get some nail varnish and mark all the pulleys relative to the head/block as it makes it dead simple to see if it is all in line. Remove the spark plugs before turning over so you can feel any binds as you wind it over by hand, then if all feels ok, crank on the starter. Recheck the tension on the belt (easy to adjust) and finally reassemble. If you get a CE light on after reassembly you likely fell in the trap of getting the exhaust cam one tooth out (due to the spring loaded pulley) so just move it one tooth and prolem gone.

You don't even need to remove the crank pulley, just remove the lower belt cover and the belt will (just!) fit through.
