Question about 1998 Plymouth Neon
With the fan kicking on normally that means that the coolant temp sensor is functioning fine, it sends a signal to the ecm to turn the fans on and off. have you had the coolant flushed lately? if so there could be an air bubble in there that needs bled out, a bad radiator cap, make sure coolant is at proper level, and is flowing and that both the upper and lower radiator hoses are getting equally warm, if not water pump may not be pumping, make sure that the serpentine belt is tight enough with no oil leaking on it making it slip. if all that is check you need to look at the gauge,and if the fans always kick on when the temp raises and then off when temp lowers. locate the temp sensor normally on the intake manifold on those, some i have found on top of thermostat housing and unplug and see what gauge does. maybe just bad gauge. is car running any different or is it running fine? hope something here helps, just let me know.
