getting the bubbles out of the radiator wasn't the prob..
as soon as i turned on the pump (closed loop) the bubbles came out and went through the pump ...

then only
LITTLE bubbles came out..
and again... and again... and...
the bubbles disappeard.. but the noise was not...
I had to buy 10L xtra of that *(^&@#&^ water before there weren't any bubbles in the hose (u couldn't see then... u HEARD em

)
