About three weeks ago, my idiot light for the engine overheating came on; dashboard temperature gauge confirmed it was overheating. I pulled over, let it cool off and added water in order to get it home(another 3 city miles). Took it to a auto repair shop close to my house here in Austin. They said I had a radiator leak; I had them replace the radiator. About ten days later, I noticed the dashboard temperature gauge reading higher than normal on my way home from work. Found the liquid level very low. Took it back to repair shop and they performed a pressure test; test came back negative and they said they couldn't find the leak. They topped off and it only took another few days before I noticed the liquid levels dropping again. This time, I took it to a Dodge dealership in South Austin. They had it for eight hours and told me the same thing - couldn't find the leak!?! They topped off the fluid level and here it is another few days later and the level is down again. I have also noticed my heater hasn't worked at all since the radiator was changed out; just figured an air bubble was trapped in the coil. Looking for possible answers or options of where I should take it for the needed repair.

If there are no external leaks, have you checked the oil for evidence or an internal leak? Trans fluid? Also, have you noticed any white smoke from the exhaust? To me it sounds like a head gasket, but let me know what you have found.
