Hi Stig,
you can buy (at least in Germany) cooling liquid at your dealer. It's 
a special mixture (e.g. from Castrol) for aluminium engines. My dealer
also uses this mixture. It's not so expensive (10 german marks for 1L). 
I would recommend this.

|Also, how to replace the coolant. Is it just to:
|- Empty the reserve tank
|- Open the radiator cap
|- Remove the draining bolt
|- Fill new coolant on the radiator/reserve tank
|- Done. ?

Due to the official repair handbook it is:
- Open the radiator cap
- Remove the draining bolt near the water pump.

- Use a NEW seal for the draining bolt.
- Fill new coolant on the radiator.

Remark to the last point. The official repair handbook sais refilling
by putting new coolant in the reserve tank (Ausgleichsbehaelter in german).
But I had to change (due to a "funny" mistake I made) the liquid a few 
weeks ago and the reserve tank wasn't empty after the above mentioned 
procedure. The liquid was quite good so I didn't empty the reserve tank.

|Is there any need to ventilate the system 

IMO, no.


Hope this helps,

  ToM
