Manual calls for DEX-COOL It actually depends on what type of coolant is in it now. If it's green, it's been traded out with normal coolant. If it's reddish, it still has DEX-COOL in it. NOTE: you should never mix the two types together. DEX-COOL and normal coolant can clog up the system if mixed together. Some places sell a type that is safe for either type of system, but i'd go with whichever is currently in your system, $5 for a gallon of regular coolant or $8 for DEX-COOL but it improves expectancy of your heating and cooling system (which the venture sure can use)

For a 2000 Chevy Cavalier, it is recommended to use a 50/50 mixture of ethylene glycol-based antifreeze and distilled water. The vehicle typically requires a coolant that meets the GM specification, such as Dex-Cool, though conventional green antifreeze can also be used if properly mixed. Always consult the owner's manual for specific recommendations and to ensure compatibility with the existing coolant.
