Use brake fluid approved to MB 331.0, or a DOT 4
brake fluid with: minimum dry boiling point (ERBP)
500
°F, minimum wet boiling point (WERBP)
356°F, maximum viscosity 1500 mm
2
/s,
conforming to FMVSS116 and ISO 4925.
In the course of its service life, the boiling point of the
brake fluid will fall due to the continuous absorption of
moisture from the atmosphere.
If the brakes are placed under heavy loads (e.g., on
steep hills) bubbles of steam can then form in the brake
system.
This will adversely affect the brakes' effectiveness.
The coolant is a mixture of water and a corrosion
inhibitor/antifreeze additive. Within the cooling
system, the corrosion inhibitor/antifreeze ensures
• anti-corrosion protection
• antifreeze protection
• a higher boiling point.
The coolant added in the factory ensures adequate
antifreeze and anti-corrosion protection.
Use coolant approved to MB 325.0, such as Valvoline
GO5, or an equivalent Extended Life Coolant.
To avoid damage to the cooling system, only use
manufacturer approved corrosion inhibitor/
antifreeze additives.
Information on the corrosion inhibitor/antifreeze
additive is available from any Sprinter Dealer.
For reasons of anti-corrosion protection and to increase
the boiling point, the coolant added to the cooling
system is designed for all year round operation – even
in countries with high prevailing temperatures.
