something has gone drastically wrong there  :o

SGI or Mixer system?

Engine coolant is used in the evaporator, it comes in under pressure then is released in pressure (coolant does its job) 

No its either then injected into each pot, or its taken in by the air-intake.

So for it to be forcing its way into the water, something has been wrongly connected on the evaporator / HBV  :-/

the only place i can think of that the water touches the gas side is the evaporator  :-/

thing is, nothing was touched on that side
it also breaked the radiator  :-/

me thinking the evaporator if breaked  and leting gas into the water >:(

anybody ??

Remove the evaporator from the coolant loop and see if it stops.

Could be a goosed evaporator

Certainly sounds like a knackered Evaporator. You can normally get "Rebuild" kits with all the rubber you need to strip it and re build it :y :y

As Mark said, disconnect both coolant hoses and link them up to confirm it :y
