cause corrosion of the aluminum components.
8. By referring to the section on coolant, select an appropriate
concentration for safe operating temperature within the
range of 30 to 60 %. Use special tool MB991871 to refill the
coolant. A convenient mixture is a 50 % water and 50 %
antifreeze solution [freezing point:
31C (32.8 F)].
Recommended antifreeze: Long Life Antifreeze
Coolant or an equivalent
Quantity:
8.7 Litres
NOTE: For how to use special tool MB991871, refer to its
