I have a 95 civic. I'm pretty sure the water isn't circulating properly but don't know how to fix or where it might stopping at. I've changed the thermostat thinking that would fix the problem checked all my hoses, radiator hoses, heater hoses, return hose etc.. I even ran it without a thermostat, when I drive it it bubble out of the overflow bottle and eventually lose all water I thought maybe I had a bad radiator cap changed that still nothing now I'm at a loss please help...

Check cooling fan operation. If the fans don't function when the system's hot...

You've stated the radiator hoses and heater hoses have been checked. What has been checked? Do the hoses heat up when appropriate? And cool off as well..

Is there any possibility that the coolant may be an incorrect mixture (not able to transfer the heat) or the coolant pump impellers have etched away, and coolant can no longer be moved?
