Hello! I have 95 neon sports. 114k miles. (I know it's crap!) It's overheating after 10 mins of driving. The shop I took it to said the problem was thermostat housing, which I replaced. Coolant is usually full, though sometimes it is gone (I don't know why). Even with coolant, it heats. If I turn on the heat at max to my foot, heat marker gradually normalizes. If I turn off the heat, it goes up again. I don't think I should be driving like this. It makes me hot. I don't wanna go back to that shop. Anyone have an idea what is the problem? Thank you! |

Replying to: 71charger (Jul 18, 2005 10:56 am) its good clean car. I just replaced timing belt and waterpump. I'd like to at least reach 150k, before dumping it. |

I have a 97 Dodge Neon Highline (DOHC) and my car is overheating. The car does fine while I am driving (because of airflow) but when it sits idle the temperature gage increases to HOT in minutes. I can see the the radiator fan is not kicking on when this happens. I also turn on the AC and the radiator fan is not starting (I believe turning on the AC, turns on the radiator fan.) To try and troubleshoot this, I put +12V to the radiator fan motor and it worked fine, so I am guessing it is one of the relays and/or switches. I checked the connection to the engine coolant temperature senser and it was good. Also, I replace the engine coolant temperature senser. I am now stuck. I checked the Haynes manual and it explains that this problem could be in the PCM (Powertrain Control Module) and should be serviced by a dealer. Does anyone have any recommendation before I go to a dealer? Would it be better, easier, cheaper to just replace the PCM. Thanks in advance for your help.

Replying to: phatbecker (Aug 14, 2005 3:13 pm) Looking in my Neon 2k manual from Haynes, the relay is shown on the electrical schmatic for the AC and physically located inside the fuse/relay box. |
