Checking Fuels Coolants Lubricants etc.
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.
The coolant level must reach:
The marking (1, arrow) on the
reservoir when the engine is cold.
Approx. 2 cm/0.8 in higher when the
engine is at operating temperature.
Replenishing Coolant
If a small amount of coolant has to be
added (due to evaporation of water),
plain water can be added.
If a larger quantity of coolant has to
be added, a 50/50 mixture of water
and antifreeze should be used.
Caution:
Do not remove pressure cap on
coolant reservoir if engine tempera­
ture is above 90° C/1940 F. Allow
engine to cool down before removing
cap. The coolant reservoir contains
hot water and is under pressure.
First turn cap to first notch to relieve
excess pressure using a rag. 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.
