Okay ladies, I have a 2003 Dodge Neon. I have had the water pump, timing belt, pulley all replaced recently. About a week later it started overheating, I had never had this problem before. I replaced the thermostat, still overheated. Then I flushed the radiator, still overheated. Do you all have any more ideas for me to try? I have put over $1500 into this car in less than a year. I am becoming very discouraged... Thank you! Crystal Hughey
Sounds like you need to return to the mechanic who performed those extensive repairs, and have your head gasket inspected. They may have missed something when they had your vehicle in the shop.

You can actually test the thermostat by putting it in boiling water to see if it opens. You also want to make sure it wasn't put in upside down.
Other than that, I would flush the whole cooling system, not just the radiator using a machine, not just a hose. Are you sure the water pump is working properly? It's odd that this problem started after you had work done.
