#68 of 91 1997 Dodge Neon Overheating
Oct 24, 2010 (7:21 am)
Where to start, I have a 1997 dodge neon and something is defiantly not right. If i have my car on for about 10 minutes my temp guage will start to rise, and eventually will be at H, but then it will slowly randomly spike back down to mid, and then spike back up again, back down, back to H, and so forth..If i turn my car off with it being all the way at H, and turn my car over to just the guages having power, or even being all the way on, the temp guage goes to about mid. If i leave the car off for awhile, the engine cools like normal. Ive tried replacing the whole cluster unit, and also tried re soldering my old one. Didnt fix it. Since ive noticed that when the car goes to H, my radiator fans dont come on, nor do they ever, thats a problem it self. Also i just replaced the radiator cap and thermostat. When the car goes to H, the therm. doesnt always open. The other day i was letting my car idle and i saw smoke coming from my hood, it was only coming from the side where the overflow tank was and the radiator res. is. And i drove it home quickly to find out all my anti freeze leaked out..weird back pressure perhaps? I told a guy who works solely on neons the symptons and he thinks its a headgasket, anyone else have any ideas?

fan doesn't kick-in when it sits and idle gauge will start to rise toward Hot,they told me its the relay so I replace the relay in the fuse box.still the fan doesn't kick-in.

i have a 95 as well i had the same problem, its actually fairly common its just the thermastat and housing replace both and it should be good if not do as suggested and check for bubbles and signs of a headgasket failure

I have a 99 neon coupe sport that does the same thing as your symptoms describe. I have learned in the past that when you replace a thermostat it best to get it from the dealership of any make of car. I done that but I dont know why a OEM thermostat works better. I have flushed the radiator. Checked all the fluid levels (oil) included. I am the second owner of the car, I bought it from a family member. It has 208000+ miles on it. There are no leaks. As I type this and after reading some other posts. I am going back to check the radiator cap. I know you said your car is a 97 model, but we both have the same symptoms. I would like to thank you in advance for any advice you might have to help solve my problem.

I read this as well before I posted my symptoms and reading it again and see it was from you. I am going to try this as well....wow... Just didn't pay attention to the posts. And you are saying because of a corroded connection from battery to body of the car would make the engine over heat? I will definitely check this out...Thanks again in advance.

I've been having the same problem with my 99 neon- did you try the battery clean up that wiggdoff suggested ... & if so did it work?

All connections to battery are clean, posts and the ground to the body of the car, but it seem strange a corroded connection to the body of the car would make keep spiking up and down between halfway of the temp gauge and to hot. I think I am going to try a complete coolant system flush. Hopefully that will work, but if there some reason that corroded connection will make it run hot then I will look at it again and hopefully check the connection to the starter, but it really don't seem logical.

hello, i have a 95 neon as well. a couple months ago it over heated for the first time since i got the car, so i replaced the thermostat and it ran fine for about 2 months. and about 3 weeks ago it over heated again, then the next day it was fine. im not sure why it would just randomly over heat like that. but again, it ran fine for another 2 weeks, and then started over heating again!!! its like the car is having mood swings or something lol idk. but this past weekend i drove it home to arizona from california and even going 80 on the freeway it over heated, so when i got here i took it to the shop. i guess the entire radiator was corroded and the fluids werent circulating correctly. so yesterday i picked it up after they put a new radiator in it. and today i was stuck at a stop light and it got hot again! im not sure what is going on here. i took it back to the shop and they did all the tests again and test drove it and it ran FINE im so irritated at this point. i hate having this 50/50 chance of my car over heating every time i drive it. obviously when it starts getting warm i turn the heater on full blast, but come on i live in phoenix and its still summer! this is not right....
PLEASE any advice or suggestions would be GREATLY appreciated!!!!!

Neons are notorious for head gasket issues so you folks better look into that. You can test for it.
