I need to drain and refill the cooling system as it drops to -27 here and so I don't want to take any chance with the strength of the cooling fluid. There seems to be a lot of hoses connected with the cooling system so do I need to find any bleed valves or follow any special procedure after I have refilled the system?

make sure your heater controlle is set to hot, after you have refilled the system warm the engine up with the rad cap off and squeeze the top radiator hose this should remove any air in the system.

OK, thanks. Didn't know if it was like my Xantia which had a small bleed valve that you had to press when you drained some fluid from the system.

Just thought I would add that if you don't leave it overnight with the expansion tank cap off, then some air will get stuck in the system. I have drained to replace the fluid etc a few times and have always had to do this and if I don't the engine does really get hot(not just showing hot when it isn't, it starts to slightly misfire at the lights and runs rough) because of the air lock, I think.
