Hi 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.

that was the first test i got done. and the head gaskets are completely fine. when i took the car back today, the mechanic even tested it again to make sure.

Okay...do you know how he tested for it. Best way is to pressurize the cooling system, then, while it's still under pressure, pull the spark plugs and look for coolant on them. Also you can test for combustion gases in the coolant by adding a chemical to the radiator.
I'm always suspicious of Neon overheats, so that's why I mentioned this. But sounds like you're ahead of me on this one!

Hi in response to your post.... I have did everything I know what to do replace the thermostat, radiator cap, water pump and now I have a radiator for the car now that I have read your post and you said you replace the radiator hell I am about scare to try it. And if I take it to the dealership it might cost out of the ying yang and they aren't going tell tell what the problem might be, just bring it in we go to look at it...right. After all the work I have done to it I guess that is what I am going to have to if the radiator replacement don't work.

i wouldnt replace the radiator until you get it checked out and see if it is corroded really bad, if it is just plugged get it flushed before you replace it. i would have flushed mine but i couldnt, it was so bad it was like falling apart since it was the original one. BUT even with the new radiator in my car it still got hot. so i dont really know what is wrong with it. im just saving up as much as i can to get a new car, I AM SO OVER NEONS!!!!!!!!!!!!

I replaced the radiator and it seem to be working just great. I have a 99 neon sport, I am just going to keep an eye on it

when i took my car back to the shop after it got hot again after i got a new radiator, my mechanic installed a plastic shroud on the bottom. its been running great ever since! BUT i got a whole new problem now haha. was turning into a gas station the other night and my car completely shut off and my steering wheel locked up. got a few different people to check it out. one says its the o2 sensor, one says its the fuel pump or filter haha. WHO KNOWS. like i said before, im so over this car. im pouring more money into it than its actually worth.
