On the black expansion tank on the 95 wrx....yes !Removed! black with no markings I can find, good eh!......when topping where do you look so you don't overfill

If it's the one I think you mean I take it to the cap level replace cap and wipe away any that might be sat on the top :) 

Ok, I'll try and get photo later

Ok mate sounds like best plan :D But please non of you in underwear again I'm still having nightmares :)

Ok....I prefer hers :)

I just read somewhere (not here) when hot, the water should be at the top just under the lip of the bottle, when cold, doesn't really matter

Your right Bouncer. It's an expansion tank not a header tank so it shouldn't be full of water when cold. Best way to refill is use about 7.5 litres of coolant to refill.

Mines always just been below the cap level and not done any harm on either scoob. And it's 7.7 litre's to be exact we was on about this on another thread ;) lol. But it was warm not hot when I checked so might be a bit lower. You shouldn't open the cap when it's hot ;) 

I have tought about getting some of this:
