Question Cooling temp nightmare!

I have been familiar with the closed system 2.7 Intrepid system for a while now. The day I bought it off the lot I went 5 miles and it overheated. The carsales place gave me a radiator and said thats all. I had changed the radiator, hoses,and thermostat and then learned about proper bleeding of the system. This lately one had started out slowly and worked its way to a fast overheating tank bubbling nightmare. I changed the cap and repaired a cut in the resevoir jug. But still quick to overheat and water dissapearing but not in oil. Si seeing a lil white smoke when it warmes up out exhaust I changed the intake manifold upper and lower gaskets. I filled the resivoir then as it warmed up i purged the air out the top with radiator cap off. It seemed fine,the temp guage came up to almost operating templine and fans worked well. I stopped it and no bubbling. So I test drove it fro 20 mins. Then came home and heard no bubbling sound. so i went a tad further with ac on and came home, it died when I turned in driveway. There was no water in the resevoir at all. I let it cool a tad and when i went to add water it started gurggling as though super hot and was on its way out the resevoir! Help what could I be missing? does when the purge valve is open and water comes through mean that the thermostat is working,radiator is working or none? Im lost guys...Marty

You might have a bad thermostat, you might have a bad head gasket (though rare), you need a new reservoir (I wouldn't trust a repair on one that already broke - the plastic can have multiple micro-cracks through which coolant oozes, and then evaporates leaving no trace - recommend OEM from dealer - aftermarket ones are poor quality and don't last long), or you may have other leak points (hoses, new radiator defective - definitely not unheard of). Obviously the coolant is going somewhere - displacing air pockets not properly bled out, external leak, internal leak (head gasket). If thermostat is the cause and no other problems, coolant should be blown thru the cap into the overflow chamber of reservoir and no place else. Could have blockage from never changing coolant over the years, using wrong coolant, or use of certain stop leaks.

I would use the factory-prescribed bleeding technique, which involves clamping off the overflow hose and overfilling using a funnel sealed to the fill hole, then releasing the overflow hose clamp to put reserve in the overflow chamber. Not saying that's the problem, but the technique you described doesn't match the "proper" technique.
