Checking Coolant Level
To check the coolant level, the vehicle
must be parked on level ground and the
engine stopped.
Check coolant level only when coolant
is cold.
The coolant should reach the top of the
tab inside the filler neck.
Adding Coolant.
If coolant has to be added, a 50/50
mixture of water and MB anticorrosion/
antifreeze should be added.
The drain plugs for the cooling system
are located on the right and left sides
of the engine block and at the bottom of
the radiator.
Anticorrosion/antifreeze, see Coolants
in Index
Warning!
In order to avoid possibly serious
burns:
Use extreme caution when opening
the hood if there are any signs of
steam or coolant leaking from the
cooling system, or if the coolant
temperature gauge indicates that
the coolant is overheated.
Do not remove pressure cap on
coolant reservoir if engine
temperature is above 90°C (194°F).
Allow engine to cool down before
removing cap. The coolant
reservoir contains hot fluid and is
under pressure.
Using a rag, slowly open cap
approximately 1/2 turn to relieve
excess pressure. If opened
immediately, scalding hot fluid
and steam will be blown out
under pressure.
Do not spill antifreeze on hot
engine parts. Antifreeze contains
ethylene glycol which may burn if
it comes into contact with hot
engine parts.
