Citroen c5 Coolant change

snaps

Going to change the coolant in my citroen c5 1.6hdi (2006), just looking for a few pointers. Looks like the current coolant is orange.
So i need to know the capacity of the coolant system, which i'm led to believe is about 7l.
So i need to buy some coolant, i'm a bit confused about which is which and if there is a right and a wrong one.
It will need to be able to cope with low temperatures (down to -30c or more).

Is it just a case of draining the old fluid out (From bottom of radiator) and then filling with new coolant, letting the engine run with filler cap off and the heating on full? then adjusting the level?

Any advice appreciated.

Oh the reason im doing this, is because im moving to another country where winters are hard and i need to make sure the coolant will be ok.

Yeah, that's it.
Drain from bottom of radiator into some old 2 litre milk jugs, not everything will drain out.
Pour in 5L of concentrate, top up with distilled water. Or better, premix concentrate and water in a old jug before pouring it in.
Burp engine

Easiest way to burp is to park car facing uphill, drive around until you find a steep hill (air will burp faster this way).
Then remove cap on expansion tank (beware, hot steam will spray out. You can use a face towel and cover cap and tank so it doesn't spray in your face). Gloves are good too.

Then have ready mixed (50/50) anti-freeze and water (distilled if you can find it) in a two litre old milk jug or similar.
Remove the top bleed screw on the radiator (if one exist on your model).
While engine runs and heaters inside are on full blast and max heat, slowly pour the mix in until the coolant starts coming out through the bleed hole.
You may have to push the throttle a little to increase flow.
Also give the rad hoses a little squeeze (be careful as to not get caught by any moving belt!)
Once the mix coming out the bleed hole doesn't have bubbles you should be fine.
Replace bleed screw and the fill coolant to the designated limit.
Replace expansion tank cap.
Make sure both are firmly in place, there is pressure in the system and if they aren't firmly on coolant will evaporate. Don't break them though.

There is a haynes manual scan here - http://www.peugeotforums.com/forums/307-38/bleeding-coolant-system-after-change-waterpump-1-6-hdi-2005-a-27152/

get the orange antifreeze of a citreon dealer and ask them what ratio to mix it for -35 protection.
