I'm going to flush my heater matrix this week as per the guide http://www.omegaowners.com/forum/index.php?topic=90620.msg1155537#msg1155537
my questions are, by doing this will it drain all of my coolant ? if it does should I put back 50/50 anti freeze and water, also how much anti freeze will I need, or can I just flush and top coolant tank up with water ?

If you are going to flush the matrix you may as well do a complete coolant flush & change change IMO.

unless it has been done fairly recently 

not all coolant will drain out if you only disconnect the matrix hoses in my experience

but whatever way you go replenish with 50/50 pre  mixed

would advise GM Pink

Thanks, will 1 litre of anti freeze be enough.

No, 50/50 mix.

The whole cooling system holds 10.5 litres IIRC. If you do a full system flush you will need 5.5 litres off concentrated antifreeze (to mix with the same quantity of water).

If you just flush the heater matrix then 1 litre of concentrated antifreeze (& the same of water) will be plenty.
