Question about 1998 Dodge Neon

1 Answer

Have a 98 neon that "thinks its overheating." i've replaced : thermostat, temp sensor/sending unit, dash cluster, fan relay, radiator, fan, radiator hoses, had the water pump tested (it is good), upgraded to a high flow/large capacity radiator with twin fans. the car says overheat but when turn off and back on without starting the guage says only normal temp. wtf is going on. my mechanic friends are stumped. dodge dealers are stumped. please help.

    new hoses... not collapsing. "claims overheated" when at idle also

    the solution to this problem was a failed/broken ground strap connecting the passenger-side firewall/strut tower to the cylinder head. mine had snapped-off at the head due to excess corrosion of the connector.replaced the ground strap and "false overheat" has been gone ever since

Unplug the fan on sensor. It should have one green wire and one black wire. Use a paper clip and jump the two wires. Turn the key to the run position, the engine does not need to be running. Does the fan come on? If not check the green wire for 12 volts and the black wire for ground. If there is no ground than run a new ground wire. If the is no power check the heater/air conditioning fuse in the under dash fuse block. If there is power and ground make sure both the cooling fan fuses are good and both the cooling fan relays are good.

Jeep keeps overheating replaced relay


A mechanic would use a scanner to check the engine temp sensor.
The temp sensor tells the computer what the engine temp is and the computer activates the fan relay when the temp reaches about 230 degrees.
Since you said relay I am assuming your Jeep has an electric radiator fan.

The electric radiator fan runs after truck is shut off. Will turn off after 30-40 min. Is this normal?


no it is not normal....have a repair shop check the coolant fan sending unit or the coolant fan relay...a bad sending unit maybe sending a false overheating signal to the fan causeing it to stay on or the on off fan relay maybe sticking on..an make sure the jeep is not actually running hot the temp guage maybe reading the wrong temp

Fan is not kicking on, have tested fan and works ok, is there a sending unit or something else I'm not checking |? 2001 neon 2.1 liter megilge@gmail.com


Yes there is a coolant temp sensor that goes bad from time to time this is what tells the ecu to turn on the fans so therefore its telling the ecu the car is not hot. This is normally located either on the radiator or somewhere close to the thermostat.

Overheating


If the fan is coming on late, it would nearly reach overheat, then after fan cuts in, the temp should go down. Temp sensor sends a signal to the computer, computer sends a signal to the fan relay, relay completes circuit and turns fan on.
Fan should go on at or just above "normal" operating temp and should be on full - time when a/c is on. Sensor may be slightly out of range, but, I don't understand why shop when testing did not see this and finish the repair....Sensor is not expensive and isn't a terribly difficult item to replace.
Personally, I've found that a problem like yours is more often caused by a partially obstructed radiator...many times flushing goes around not through the obstruction and does not correct flow problem.

The cooling fan is not working and it is running hot but not actually overheating. can a bad thermostat cause this problem? i replace the fuse but this did not fix the problem


Yes it can. To verify, unplug the temp sensor at the lower radiator hose. If your fan turns on then you have to replace the temp sensor. Otherwise swap the relay of the AC fan with the radiator fan. If it turns on, have the relay replaced, if not have the fan replaced.

2001 Oldsmobile Alero overheating


I think you started out looking in the right places. Replacing the coolant, thermostat, relay and sensor are all fairly inexpensive.

I believe you either have blockage in the system (especially if you're using tapwater), or your water pump may be failing.

I would first either take it to a radiator shop and have them flush the cooling system out thoroughly, or else pick up a chemical flush kit and do it yourself. This involves more than just drain and refill.

If this doesn't work, your next step will probably be replacing the water pump. At almost 200k miles, it's probably about due anyway.

1990 silouette 3.1 v-6 looking for the temp switch, replaced temp sensor, fan relay and fan ( fan tests good and runs independently) still won't come on. Temp gauge is jumpy and showing 240-260. replaced...


hey if it was constantly running at these temps you would dhave definately damaged the engine by now. the temp guage is integrated with the instrument cluster and not replaaceable unless the whole guage cluster is replaced. you could go to a professional installer and have an aftermarket temp guage installed. much cheaper than having your instrument pannel replaced. in addition to the instrument pannel being replaced the odometer millage must be programed into the new pannel. if the fans are not turning on the engine more than likely is not getting hot enough to turn them on. but just to be sure i would take the vehicle to a automotive diagnostic specialist to make sure the ecm (electronic control module) is performing correctly. it may not be sending the signal to the fan relay to turn the fan/ fans on. you may also have a faulty temp sending unit. good luck.

I am having trouble with my speedometer not working occasionally and now my seat belt light is coming on sometimes too. Is this the instrument panel cluster? Or something else? 1998 Dodge Neon. Backstory is as follows: -We take very good care of it and have one dedicated mechanic. -It has only had two owners; my parents and I. -We replaced the battery 2 months ago. -Mechanic checked to make sure the speedometer sensor was working. -We have had issues with the radio for years where it will randomly turn on and off, typically brought on by a stuffed trunk OR wet weather. -The speedometer works until we hit a bump and then the needle flies up and down or sometimes just stops working all together. -Mechanic has made mention of there being some Chrysler specific battery cable that is a smaller side cable and it is not in good condition. -Currently, my problem is that I can't find an old 1998 Dodge Neon in the salvage yard because yards are doing a lot of 2002 and newer vehicles and automatically crushing the others. The meat and potatoes of my question is what direction do I go in? And what of these symptoms ties to each other? And will adding new solder to the points on the panel fix it or is it something else? I'm trying to find least expensive to most expensive options and I'm rather handy but can't drop an engine or transmission or anything so keep this in mind. My handiness ends at resoldering the pins BUT I do have a mechanic I trust, but I fear that maybe I'm not combining symptoms properly. I have the money to repair an item I KNOW is wrong but not to chicken hunt around for problems.
