car overheating!!! Options

[SiN_CeLi]

Hi everyone, I really need some help. I have a 96 gt and my car will not stop overheating. But the wierd part is that the temp guege reads normal so the fans don't kick in anymore.Everytime I park my car my radiatior dumps all the coolant out through the reservior. I think that my thermostat went bad but I am very open to suggestions. I already posted on a different site but know one could help me or they just chose not to.

I'd be leaning towards a blown head gasket, combustion pressure going into the cooling system and forcing it out the reservoir, time to get the cooling system pressure tested, another way to tell sometimes is to feel the radiator hoses after you start it, if they get real hard feeling real quick, chances are combustion pressure is going in to the cooling system, try it with the rad cap on and off. it will also 'blow bubbles' in the radiator when you rev it with the cap off, you'll see lots of air bubbles come to the top,,,

Or it could be simply a bad radiator cap. they normally push some out in to the reservoir when running, then suck it back in as it cools, Try a new cap?
