MAINTENANCE MANUAL
3.6.19. Engine cooling liquid change
• Remove the drain plug and drain the coolant.
Note:
• The total volume of the engine coolant is 1.2 litres (0.32 US
gal).
• Open the cooling system by removing the overpressure
plug on the expansion tank.
• Fill the cooling system through the opening in the expan-
sion tank.
Remove the filling plug only after the temperature of
the engine coolant drops below 50 °C (120 °F). If you
remove the plug at a higher temperature, there is a risk
of scalding caused by steam or coolant due to internal
overpressure.
The level must not drop below the lower mark.
Refill only with a coolant containing antifreeze agents on
the same basis according to Chapter 3.2.3.
Do not put any additives for the repair of cooling system
leakage into the engine coolant!
Do not refill cold coolant into a hot engine. There is a
danger of damage to the engine castings.
In case of larger losses, find out where the cooling sys-
tem leaks and repair the cause.
Avoid leakage of oil to the soil.
