Coolant

When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable water.

To maintain the integrity of the coolant and the cooling system:
^ Add Premium Engine Coolant.
^ Do not add orange-colored EXTENDED LIFE COOLANT. Mixing coolants may degrade the coolant's corrosion protection.
^ Do not add alcohol or methanol or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing.
^ Do not mix with recycled coolant. Use of such a coolant may harm the engine and cooling system components.
