Dodge - Neon :: 2005 - Overheating / Cooling Fans Are Not Coming On
Jun 29, 2014
2005 Dodge Neon SXT 206XXX
Long story short on a trip (about a 1 hr. drive) got about a block away from destination and gauge showed it was over heating. Stopped the car started up after five min. just fine. Got home replaced the thermostat and cap (old cap was junk). New cap was junk aftermarket so yesterday I took the same car on a half hour drive to get a Mopar cap ran just fine up again until a block away, pulled off the road turned it off let it set a few min. then didn't even show it was over heating. Let the pressure off and replaced the cap and added in a bit more coolant ran fine all the way back (even pushed speed in a few spots).
The above is just what seems to be the mechanical side of the issue. After noticing the gauge was going a bit above the normal spot I noticed my cooling fans are not coming on. Checked fuse and tested relays out to be fine. First thought is to check voltage to the fans but also tempted to check coolant temp sensor with bench test. Will be going over to my dads to do voltage testing later today.

I have had some ongoing issues with this car the last 3 years over overheating, I have like clock work been replacing my thermostat in the line, well this time I replaced that danged thing again and the heating was still an issue, (yes oil and coolant filled. ) so I replaced the sensor in the motor and the fan would still not engage . so I pulled the fan and connected direct current to the fan and it did indeed start right up. so its not the fan motor, I hooked a direct current where the ah hell mental block here the plug sensor by the fuse, that was replaced, and yet still no fan engaged.. Here is the rub, If I have the AC on the motor fan will run...

I have a 2003 Dodge Neon and recently had transmission work done on the car. When I got the car back the radiator cap was left loose, I didn't know this until I took the car for a drive and it overheated. I let the car cool down, replaced the coolant, and made sure the cap was sealed down. The car now has a slow coolant leak, when I turn the car off I can see it drip underneath for about 2 minutes and then it stops. Also, after the car heats up to running temperature I get a burning rubber smell coming through the vents. What could this be? The car only has 70,000 miles on it and I would like to keep it going if I can.

I would seem that my Neon has started a very small leak seems to be coming from the drive shafts. You may call the differentials. You may also call it a transaxle. I prefer to call them driveshafts and transmissions. I took it to a service place to take a free look at it. I do not have the equipment that they have. They put it on the hoist and when you walk under there it does look like it is coming from one of the driveshafts. They were not Tranny experts and said they could not fix it, but said it would need to be rebuilt or changed. My question is, since they are not tranny experts. Does something like this really need to be rebuilt? Is there not just a seal leaking that can be changed without a rebuild? Why would they make something like that? Just to make you pay more money to get it fixed? I did try some Lucas and then Trans X hoping that would seal it up. Lucas seemed to do nothing. Just put in the Trans X today.

I have a 2000 Dodge Grand Caravan that has 195,000 miles. My radiator fan won't turn on and I'm stumped! The issue presented itself with a check engine light and the radiator cooling fan not turning on. The trouble code indicated the cooling fan relay was faulty. In all cases below, I tested the radiator fan by turning on the air conditioning (thus forcing the cooling fans to run) and also for it to come up to a high temperature coming close to the danger zone.
1. Fuse - first tested the fuse and it was OK. Had to start with simple things first.
2. Cooling fan relay - I replaced the relay which has a reputation for failing on the Dodge. Still the fan did not kick in.
3. Cooling fans - tested the cooling fans and the motor was seized. Replaced the cooling fans and tested them by jumping them. The cooling fans still do not turn on. There is no voltage leaving the cooling fan relay and coming into the cooling fan harness.
4. Wiring - tested the wiring between the relay and the fans. They checked out OK (good continuity and resistance check). There is no voltage leaving the cooling fan relay. Now it's getting more complicated... I unplugged the wiring harness from the ECM and tested the wiring between the ECM and the cooling fan relay. A-OK.
5. ECM - it is unclear how to check the ECM for functionality of the cooling fan.
There are 3 wires (supply, ground, and switch wire?) The supply voltage and ground is good, but I don't know what voltage the switch wire should be. I've read that it is pulse width modulated so I can't measure this with a simple voltmeter. I've also read that the switch wire goes to ground thus triggering the relay. I don't know which is correct. Several mechanics I talked to were skeptical that the issue is with the ECM, they knew of very few instances of this being the culprit. I even replaced the new cooling fan relay with another new cooling fan relay on the off chance that the replacement was faulty. Did I miss something in my logic and diagnostics? I've resorted to wiring a switch directly to the cooling fans and toggling them on and off.

My 2003 Dodge Neon started overheating. We replaced the thermostat, temperature sending unit, flushed the radiator, checked for blockages, cleaned the radiator, changed the head gasket and water pump.It can run for about 10-15 minutes driving or 30 minutes idling before it overheats. The fans will kick on. The thermostat opens up. Pressure builds up on the radiator hose. When it gets hot, it boils back into the reservoir.I've been careful not to let it get into the red since the head gasket change.We sent the head off and had it planed.

I have a 2000 Dodge Neon with a 2001 Neon motor in it. I have just recently had problems with the car overheating. So we started diagnosing it and replaced parts that we thought were wrong. We replaced the water pump, thermostat, radiator cap, and timing belt. The problem that I am having is that the car won't take coolant out of the reservoir tank. I have bled the air out of the cooling system and it still didn't fix the problem.

1995 dodge neon... When I turn the car off, it burps, or bubbles air into the overfill tank. Car now also overheats when idling or in stop and go traffic. Temperature goes down when running heater.Not sure if it is the water pump or an issue with the radiator.

I have a 2003 dodge neon, a couple days ago i hit a bump and bottomed out on the front bumper and pulled a transmission hoes. after repairing that my car is now over heating, i have replaces the thermostat and the upper radiator hose. i am not leaking coolant, i have talked to several people on this and they say that it is either my water pump or i have a vapor/air lock inside the block, when i was replacing the thermostat i noticed that my coolant was a milky tannish color and was "chunky" and that is what is making people say that it is an air lock. but my hear is not blowing hot air, that makes me believe that it is the water pump.. when i start the car it take the usual 10 or so minutes to reach normal temperature just like it did before all this, but then it shoots up to almost over heating in less than 5 or so minutes.. I am really stumped by this and i am a college student so i rally cannot afforded a mechanic unless absolutely necessary....

In the process of resurrecting my 93 SSEI after running at idle for awhile the engine was pretty hot. I noticed the fans never came on. I unplugged the temp sensor and both came on. So would the problem be the temp sensor, thermostat, or relay. I am not sure what the actual engine temp was because my Cluster only works when it wants to, usually when its warmed up and going down the highway or when I mat the throttle.

As the title says, car is overheating. Car gets to 190F within a couple miles drive. Temperature fluctuates between 190F and 225F.
Water pump was replaced ~2 months ago. Was not overheating prior. Temp reached 190F and stayed. Currently has the "black top" coolant temp sensor.
I noticed the coolant fans are not running after I turn the ignition off. This time of year they would usually be running after turning the engine off. If car is overheated and with AC off the fans do not run while engine is running.
I used the guide below to try diagnosing the cause: [URL] ....
Remember both fans should come on in slow speed any time the key is on and the AC is on - if the temperature is above about 32 F (0 C). Both fans run with key on and AC on
S180 (fuse 8, 30 amps, green plastic, above battery) must be good for slow speed operation.
Fuse and holder look good: no melting, no discoloration.
S164 (fuse 3, 40 amps, metal strip, above battery) must be good for fast speed operation.
fuse looks good: unbroken.
To ensure the AC circuits and the Fan Control Module has power check:
Fuse 5 on the cabin fuse panel.
Fuse 16 on the cabin fuse panel. When this fuse is blown the radiator fans will often run unexpectedly.
Fuse 25 on the cabin fuse panel.
All three fuses look good: unbroken
For the first test of the slow speed fans from the radiator thermoswitch have the key off.....Both fans should run in slow speed.
Passed test: both fans run slow
The second test is for the fast speed fans, key on, AC off.... Both fans should run in fast speed.
Passed test: both fans run fast
If the fans run in the tests above, then you should be good to go. No further tests are needed.
If you have been seeing high coolant temperatures and the fans have not been running, then you may need a new thermoswitch.

Intermittently (although lately it's pretty common, perhaps due to the Texas heat?) my car will take several seconds to start. It sounds like the battery is dead, i.e., it sounds as if it's about to start but it straining, and then it eventually engages.
When this happens, I know that a) I won't be able to turn on cruise control and b) I won't be able to accelerate easily. at best I can get it to 60 mph
Similarly, even if I start up without a problem, and I'm cruising down the HWY at 80 MPH, the car will suddenly loose momentum and won't go above 60 mph. And I can't turn on cruise control (cc shuts down, in fact, if it was on).
This is a 2005 Neon, by the way.
I have replaced the battery and cabling to the battery to no avail.

One of the gas stations where I live recently added e15 and e30 gasoline to their pumps. I drive a 2005 Dodge Neon SXT and was wondering if either one would be ok to put in this car. I regularly put in the e10 gas and have done so for all of my vehicles since I have been driving. I read that e15 should be fine but was wondering about the e30 gas.

I have a V8 engine, and I have been getting the coolant overheating warning come on once in a while.
The engine fans go crazy, and the temperature needle on the small round gauge climbs all the way to red then the coolant overheating warning comes on in dash screen.
This can happen right after I turn the car on, or on occasion, it can happen as I am driving around the city.
I stop, switch the car off, and I turn it back on after a minute, and the car is just fine. So, basically, it doesn't seem like the engine coolant is actually overheating, but the fans and warning systems seem to think that they are. The fans are pretty loud, and its noticeable when they go on, and when this happens, I know that the needle will go all the way up and the warning will go off. I also know that if I turn the car off for a minute, and it will be just fine.
The conditions are random for when this happens. So its not when its particularly hot or cold or anything predictable. Could this just be a sticky thermostat? Is it a bad water pump? Bad battery?
The trouble is that now I am afraid I cant take a real drive. Around the city I can just pull over, but I am afraid to take the car two hours out or something.

My stepson's 2005 Dodge Neon sometimes won't start. Turn the key, the dash lights and radio and electric stuff respond, but other than a click there is nothing of an engine start up going on. He'll turn the key a few times, he pumps the gas pedal, does what he thinks might wake it up. Usually it will start after a few tries. He thinks it gets worse in the cold weather, but not much worse.
He also notes that if he does a lot of short trips, like running errands, this problem comes up more often. The car may run fine for weeks, and then the problem hits. Of course, it never does this when the mechanic has it. The mechanic has no idea what to do, since the car works when they test it. I was wondering if I used a voltmeter could I check some key nodes when the problem comes up. Also, if it really does get worse at cold, can I spray some suspicious locations with freeze spray to try and instigate the problem?

I have a 2005 Dodge Neon. The heater stopped working. The blower still works so I am pretty sure the fuse is ok, at least I can't find a separate fuse for the heater. All I see is the blower for the AC/Heater. I replaced the Thermostat and watched it working by letting the car heat up and watched the engine heat drop after a bit. Still no warm air out of the heater. I tried flipping between Cold air and hot air and can tell a difference in the sound of the air blowing that SEEMS to indicate that the flap in the Dash is working to go from cold to hot air. I am sort of out of ideas unless the heater itself is hosed.

My '05 Dodge Neon's engine just quit when I was stopped at an intersection. All the lights, etc worked. When I turned the key the engine would sound like it started for a brief moment, but it always died a second later and didn't respond to pressure on the gas pedal. I took it to a shop that replaced the alternator, throttle sensor, and "idle air control mtr". A few days later, the car died the exact same way when I was driving down the road. I took it to a second mechanic who looked it over the next day, and it was running. He couldn't find the issue, and it didn't die when he drove it. I don't know if these symptoms are related, but a few minutes before it broke down the first time it jerked and the gauges went crazy. I had a check engine light for "not reading fuel level" or something like that after the first repair but before the second break down, which my first mechanic dismissed as not really important when I asked him about it. My lights also flicker a lot. Battery was replaced last year.

I have an '05 Dodge Neon SXT (4.0) with 113,000 miles on it. A few days ago, I had three cracked motor mounts replaced. However, I'm experiencing an increased amount of vibration when the engine is idle. I've had the timing belt , the accessory belt, water pump and valve replaced within the last year. I also recently had a coolant flush and an oil change. I was told that the timing belt cover is broken and I intend to have that fixed in the near future. However, I do not believe the timing belt cover is the cause of the vibration since it was broken and did not cause vibration before the motor mounts were replaced. Why I having the vibration?

My Neon tranny has been acting up lately with the cold weather. When I first put it in gear, if I do not keep it at a near idle sometimes the transmission will go into a total neutral mode. You have to just stop, wait a minute or two, and then begin to take off very slowly.
Once I get couple blocks it works fine. The temps have been in the 30's lately. Will get colder. I have been letting it warm up for about 5 mins before I drive it. I think it may work more if I leave it run longer, maybe 10 mins. The fluid level is full.
Could it have something to do with the fluid being cold? If so, would letting it idle for a very long time, 10 - 15 mins solve this problem? What is causing this? What can be done?

Original owner of a 2005 Excursion 6.8l v10, 155k miles. About a month ago 10-15 minutes or so into my ride to work on a 50-60 degree morning the check gauges light comes on, noticed the temp gauge pegged to H followed by the check engine light, then limp mode. Turned on front & rear heaters and cold air was blowing. Pulled over, checked under the hood, coolant wasn't boiling, tank was 1/2 full and cold air was blowing thru radiator. 1st thought was T'Stat. So I removed T'Stat added some antifreeze & continued to work w/o a t'stat. Then had heat thru radiator & heat in front & rear heaters. Engine ran cool with no overheat issue.
Bought aftermarker T'Stat (slant) put that in and everything back to normal. About a month later same problem happens at about the same point in my trip to work, temp pegs, no heat from heater and goes into limp mode. Shut the truck off release pressure from radiator and coolant level goes down, seems to feed back into engine. Start the truck up temp goes back to normal and everything is fine for the rest of the day with several starts/stops. Bought FORD OEM T'Stat & replaced. Next morning same problem. So i think maybe there's an air pocket somewhere, add more coolant & fill to proper level when cold. next morning from cold start same problem. Coolant is clean, just changed oil and no coolant in oil. Problem only happens from a cold startup in the morning.
I'm at a loss. I'm thinking of drilling a small bypass hole in the T'Stat.

My 2005 Neon has had a leaking problem for quite some time. It rains...a lot! After a decent rainfall, when I start the car and the first couple times I accelerate, there is an audible hissing sound, and then the water drips in from underneath the dash on the passenger side. The leak is getting progressively worse, and I'm concerned the interior carpets will get moldy. I recently brought the car in for it's 60K checkup, and all is good. The only thing they could find leaking are the seals on the passenger door. Unfortunately, these seals aren't made anymore, and the cost to purchase them is quite expensive, and may or may not fix the leaking issue.
