Air pocket somewhere? Are all the hoses hot? Does it overheat at idle or driving? Fans coming on?

yes they told me about air pockets and how to fix them and yes hoses r hot but i noticed they dont have that much pressure on them...it heats up faster when driving. and yes fans are coming on

With the radiator cap off (Cold) and engine running is there coolant flow? Water pump could be on its way out... Also check the radiator/condenser for blockage. In the first post did you mean you have no thermostat or just no leaks at the thermostat?

you need a thermostat !with out it the water moves too fast to absorb and remove any heat from the engine.get a stat and add the proper coolant.
