Re: what coolant to use for 2001 plymouth neon
2001 most chrysler products switched to GO5 antifreeze. DEX cool will not work and should not be mixed. Check in your owners it will tell you. Or they make antifreeze now called all makes all models by prestone that will work. Please rate

Is the coolant low ? Do you know where the heater hose's are under the hood in the engine bay ? Back of the engine bay going into the fire wall , feel and see if there are hot . Is one hot and the other only warm . What does the coolant look like ? GM vehicles use Dex-cool , adding regular green preston can cause thing's to gum up an clog . Air introduced into the cooling system can cause Dex-cool to turn into a muddy looking substance an clog thing's up .Can you switch the air modes from floor to defrost , will A/C work .
You need what is called GO-5 coolant. It is a Chrysler HOAT coolant
manufactured by Zerex similar to the GM DEX-COOL coolant . It is a long
life coolant. The MOPAR long life product is orange in color.
problem is with the 'dex-cool' coolant(red) that GM insists on using; when it gets old or contaminated..it turns acidic or whatever...and it eats up the motor intake gaskets; GM v-6s are affected by this;(google dex-cool' problems and you will see for yourself); these gaskets will need replacing and once replaced....flush out dex-cool completely and replace it with the green coolant...you will not have any problems after that..
Sounds like air in system, repair any leaks flush and add universal antifreeze, and to get air out without special equipment, fill best as possible, start engine drive around block. Let vehicle set until cold. Then check coolant level again, repeat until guage stays normal
Start with the simple and replace the thermostat and also replace the coolant. The Dex-cool is only good for 150,00 miles or up to 5 years and any thing longer then that, the coolant crystallizes causing a flow restriction throughout your cooling system.
There is a TSB for thew servicing of coolant that needs to be done before replacing the Dex-cool. The cooling system needs to be flushed out to get the crystal deposit out of the system if there is any.
Gm uses Preston radiator flush to clean out the radiator and heater core of any deposit that will restrict the coolant from flowing throughout the system. Once the system has been flushed out, replace the thermostat and replace the Dex-cool with a 50/50 mix of water and Dex-cool for the best result in cooling. Too much water and the coolant will boil over and too much Dex- cool will jell up causing poor circulation.
Thank you for using fixya and good luck
It sounds like you have air in your cooling system, Check your coolant level and add if your low. Fill the radiator if your low on coolant and the over flow tank with GM Dex cool with 50/50 mix of water. open the radiator cap to the first click to allow the air to work it's way through out the system and out through the radiator cap and in to the over flow. Once the engine cools down, the coolant in the over flow tank will flow into the radiator, so keep an eye on the over flow tank and refill to the full mark as needed. If you have not flushed out the coolant system, you may want to. The GM Dex cool has a life expectancy of 5 years or 150.000 miles, and should be replaced. The capacity of your cooling system is 11.5 liters, good luck.
Dude you should have a drain plug on th bottom of the radiator. Remove and drain it out, run water through the system for a good ten minutes. Then reinstall drain plug and fill your cooling system with the correct antifreeze. You fill canister should be on the left side of the car and you should use GM Goodwrench DEX-COOL or Havoline DEX-COOL coolant.
