Hi there,

Thank you to the welcome forum for pointing me to starting a thread.

I have a 2005 Dodge Neon SXT.

I am having trouble with coolant bubbling into my overflow. If left alone, the car does overheat, so, I have been using a transfer pump to put it back into the radiator about once a week. I have no hydrocarbons in my coolant and I have no coolant in my oil. I am not losing coolant either. I have replaced my cap and thermostat. No loss in fuel economy and the car runs great otherwise. Heater works fine, but when it begins to overheat, the heater works intermittently. Water pump was changed with the timing belt about 12,000 mi ago.

I don't think it is the head, but I am at a loss as to how this is happening.

Any advice?

Thank you
Dean
