    You can change Coolant types only after you have Flushed the cooling system. You should never Mix coolant types. The most common change is Dexcool to Universal Long Life. That's going from Orange to Green or Yellow. But as a rule you should stay with what the manufacturer says. If the car uses Red or Blue coolant, stay with it. European cars are more sensitive to coolant changes.
