Example
Checking Coolant Level
The coolant level can be checked
visually at the transparent coolant
reservoir.
To check the coolant level, the vehicle
must be parked on level ground.
Check coolant level only when coolant
is cold:
The coolant should reach the rib in the
filler neck. Also see marking (1) on
reservoir.
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 194°F (90°C). 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.
