It came with good old fashion Green antifreeze. Fill with 50/50 mix of antifreeze and distilled water or you can buy premixed. But you can make 4 gallons of your own for about $8 more than 2 gallons of the premixed stuff👍

Make sure there isn't orange coolant in there. If there is make sure to really flush it out. Green doesn't mix well with the new stuff and a lot of times people put the dexcool since the modern ones now use it.

Nothing wrong with green except you have to change it more often than Dexcool, or other extended life antifreeze. Dex will not hurt your cooling system as long as you get all the old coolant thoroughly flushed out. But no matter what you use you should get all the old coolant thoroughly flushed out.
