Checking Coolant Level; Adding Coolant - Mercedes-Benz 190 E 2.3 Owner's Manual

1 Coolant Filler
2 Marking for coolant level

Checking Coolant Level

The coolant level can be checked visu­
ally at the transparent coolant reser­
voir.
To check the coolant level, the vehicle
must be parked on level ground.
The coolant level must reach:
The marking (2, arrow) on the reservoir
when the engine is cold.
Approx. 1 cm/0.4 in higher when the
engine is at operating temperature.

Adding Coolant

If a small amount of coolant has to be
added (due to evaporation of water),
plain water can be used.
If a larger quantity of coolant has to be
added, a 50/50 mixture of water and
anti-corrosion/antifreeze should be
used.
Warning:
Do not remove pressure cap on cool­
ant reservoir if engine temperature is
above 90°C/194° F. Allow engine to
cool down before removing cap. The
coolant reservoir contains hot water
and is under pressure.
Using a rag, turn cap to first notch to
relieve excess pressure. If opened im­
mediately, 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.
