2000 dodge neon overcooling
I have a 2000 dodge neon es. I have recently rebuild the cylinder head due to a low compressed cylinder 3. While having the cylinder head off, I replaced the radiator, water pump, thermostat, all seals and gaskets, belts and other parts. After putting everything back together, i drove the car on the highway for 6 hours, the whole time my temp gauge would read cold... When i pulled over, the engine temp increased to operating temperature. My first thought was the thermostat was stuck open. So i drained the coolant and took out the thermostat, and infact it was stuck open. I replaced it with a new one. 4 days later i was having the same problem but the temperature wasnt all the way down, just a line above cold. It takes it long to warm up, any idea???
