warning When removing the radiator cap, use care to avoid contact with hot engine coolant or steam. Place a shop towel over the radiator cap and turn the radiator cap counterclockwise a little to let the pressure escape through the vinyl tube. After relieving the steam pressure, remove the radiator cap by slowly turning it counterclockwise.
Drain the engine coolant from the radiator, heater core and engine after unplugging the radiator drain plug and removing the radiator cap.

caution Do not use alcohol or methanol anti-freeze or any engine coolants mixed with alcohol or methanol anti-freeze. The use of an improper anti-freeze can cause corrosion of the aluminum components.
By referring to the section on engine coolant, select an appropriate concentration for safe operating temperature within the range of 30 to 60%. Use special tool MB991871 to refill the engine coolant up to the top of the radiator port. A convenient mixture is a 50% water and 50% antifreeze solution [freezing point: -31°C (-23.8 °F).]

    Recommended antifreeze: Long Life Antifreeze Coolant or an equivalent
    Quantity: 7.5 dm3 (7.9 quarts)
