I have let it sit, jacked up the pass side to get air out.I have opened up both bleeders. I have done this for 2 days. I think it has a blown head gasket, cause of the burping and bubbleing. I am not for sure though. Could someone please shed some light on this for me please? All help will be greatly appreciated.

remove the spark plugs to reveal any coolant..
when engine is running and cap is off it bubbles this is the head or/and gasket. the reason it overheats is the water pump only pumps water.
