[quote:5e100f5931="ocmike"]My 04 neon SXT (45000M) starts to overheat when the car idles for a moderate amount of time- or I run slowly (as the earlier post states). It runs fine on the freeway- but in traffic it gradually heats up. I thought thermostat- but noticed the electric radiator fans not working. Is waterpump the answer?
Any thoughts?

Do you hear any boiling upfront-fans not working tells that you have a airflow problem-get an $18.00 so that you can find the relay and for future use.
Water pumper to nail this bad boy run engine for 5mins. Caution: use a protective device squeeze the upper hose on everything you got let go -do you see/hear thru the hose a rapid fire movement of flow.
Also another cheap way to figure it out is fill the radiator to the brink fire it up and observe for coolant swirling around. if you got both the pumper is doing fine
Try bleeding the system follow the procedures and see what happens.
Always bleed air from cooling system after replacing coolant. Set heater for maximum heat. Remove radiator cap. Loosen drain plug and remove drain bolt (if equipped) from engine block. Drain coolant reservoir. Fill coolant reservoir to MAX mark with 50/50 water-coolant mixture. Loosen bleed bolt and fill radiator up to base of filler neck. Close bleed bolt when coolant flows out without bubbles. Tighten bleed bolt. With radiator cap removed, start and operate engine to normal operating temperature. Add coolant if necessary and check for leaks.
Good Luck-Bye
