I have a beautiful omega 2.2 petrol  2002 model, over the last two day she has lost two litre of coolent but i cannot see any leak or wet patches.

i have check the oil and it is fine does any body have any idea's is it going to be expensive ??

What should i do

next problem i am in Spain at the moment 

also this may be nothing to do with the water like but when you start the car after it has been off for over a hour it runs lumpy for the first 30 seconds your it to rev the car its as if the car is not getting enough fuel

Might be the heater bypass valve. HBV.

Situated at back of engine , in front of steering wheel (RHD car). It joins 3 pipes together and are prone to the membrane failing. Looks like a miniature star ship enterprise.

Wherabouts are you in Spain?

If HBV is OK, leave car overnight, before starting engine remove plug #4 and check for coolant on piston crown
