Have not done the fuel filter yet on mine but I did changed the coolant on my S80 last month.

Yes there will be pocket of air trapped around the thermostat so the fluid will go down when the engine is fully warmed up. But no worries. It does not go down that much as in it would overheat the engine. The low coolant warning will come up first. Just fill it up till the cap (above max) and wait for the level to come down when engine warmed up. Top up when it safe to open the cap.

And don't bother with the block coolant drain screw ... only 100ml came out on mine.
