Checking Coolant Level; Adding Coolant - Mercedes-Benz 190 E2.3 1985 Owner's Manual

1 Coolant filler cap
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
anticorrosion/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
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.
