[Anonymous-0]

is it air in the system or a craked? head or block, runs fine, no water or antifreeze in the oil, but it is overheating and bubbling and burping, my brother said it has air in the system,how do I get the air out? how can I check?
can I pressure check it, i put a new thermostat in it the other one was stuck open, never had this problem with my Molines.

Bubbles in the coolant are generally caused by a blown head gasket. It could be a cracked head but a blown headgasket is more likely. Generally, any air in the system would be purged in the first opening cycle of the thermostat. The only other possibillity I can think of is bad pressure cap which would make the coolant boil when the engine was used heavily.

Ditto what jerry said.

in addition, yes.. there are pressure and leakdown testers that clamp onto the rad in place of the cap... fried rice-tool store should have then cheap.
