Adding Coolant

If coolant has to be added, a 50/50
mixture of water and MB anticorrosion/
antifreeze should be used.
Warning!
• Do not open the engine hood if
you see or hear steam or coo­
lant escaping from the engine
compartment. With the engine
off, wait until no steam or coo­
lant can be seen before opening
the hood.
• Do not remove pressure cap on
coolant reservoir if engine tem­
perature is above 90°C (194°F).
Allow engine to cool down be­
fore removing cap. The coolant
reservoir contains a hot water/
anticorrosion/antifreeze mixture
and is under pressure.
• Using a rag, turn cap to first
notch to relieve excess pres­
sure. If opened immediately, hot
scalding fluid and steam will be
blown out under pressure.
The drain plugs for the cooling system
are located on the right-hand side of
the engine block and the bottom of the
radiator.
