the coolant will overheat without a thermostat because the water keeps cycling through the motor and radiator, and doesn't get a chance to cool down. the thermostat keeps the water in the radiator so it will be cooled and then releases it into the motor when needed to cool the motor.

replace the thermostat, its not much money use coolant not water and lastly check the radiator cap as well

Have you seen water and coolant leaking out? From where?

I have same year Neon. The entire coolant system went to crap. Started with water leaking out of bottom of overflow tank (yes, these wear out like anything else). Used Bondo to patch 2 holes in tank - it works fine now. The small diameter hose leading to overflow reservoir was full of rust, took a while to clean it out properly. Replaced electric radiator fan (it seized) and the thermostat. Car still overheats but not dramatically. I'm gonna replace radiator next ($110) because I suspect tiny tubes inside are probably clogged up. Previous owner never flushed system ever and I have 217K miles on car and water was so orange could paint with it! No matter how many flushes you make, once a rad turns on you it's too late to save.
