With antifreeze, you must use proper one called for your wheels. Prices vary. Flush kit to hook up and flush $9.98. The antifreeze varies, may need 2.5 gallons or more. 50/50 is cheap not worth going that way. Better off mixing your own. Good antifreeze could be $20/gallon. If you mix your own that's 2 gallons. Might as well change thermostat and gasket as well.
