    There is or should be a plastic tank hooked to the radiator, it may be clear of white and you should be able to see if it is up to the mark or not. Don't add more than you need or it will boil away.

    Your overflow bucket under the hood that holds anti-freeze is low, when you add Dex-cool the float will rise and turn off your dash warning lite

    probably low on coolant from a leak usually the waterpump or crossover tubes gaskets leak. take it in and get it leak tested
