Don't just assume it's the radiator. Before you start throwing parts at it, get a block test kit from Napa or rent one from AutoZone or any parts store that has a rental program and test for exhaust gases in the coolant. Without spending any money you can check the purge line for flow, the surge tank cap to be sure it holds pressure, the water pump belt tensioner to be sure it is providing enough tension to the belt. Also don't add "water". Add a 50/50 mixture of Dex-Cool and distilled water.

why not just water? im really sure its the radiator i can see where the water leeks down the side but i will take it to auto zone. would it help if i had auto zone use OBD ( what ever that is ) to read the codes? cabt hurt right i really like the car i hate that its not tip top thanks

Water has a boiling point of 212 degrees F. A 50/50 mix of Dexcool/water has a boiling point of 265 degrees F at 15 psi.

Because the cooling system operates at temperatures above the boiling point of water you need to add a 50/50 mix of Dexcool and water. Otherwise local boiling of the water in the system can cause issues.

Well, if you see it leaking, that's another story.

Coolant has lubricants for the water pump and anti corrosion additives in it. Water does not.
