It *may* be Dexcool, but if it's not, it'll be standard green ethylene glycol coolant. If it takes Dexcool, the coolant will look orange-colored and it will have several stickers underneath the hood around the radiator, support, and/or overflow bottle that are labeled Dexcool and calling for a 100,000 mile service interval (bad idea).
