Welcome to JustAnswer, my name is XXXXX XXXXX I'm here to help get your problem resolved. It holds 20 quarts if you have rear heater and 17.5 quarters if you do not have the rear heater. It also uses Dexcool which is the orange coolant but a lot of people switch to glycol which is the green coolant as it is easier on gaskets. Let me know if you have questions or if there is anything else I can do to help. Thanks.
