4.9.8 Cooling system
NOTE
Lack of coolant can cause malfunctions
X
The coolant level should be between the “MIN” and “MAX” markings on the
expansion vessel.
X
If the coolant is below the MIN marking, this indicates possible leakage in the
radiator system.
X
Do not continue using the truck.
X
The truck may only be started again once the cause has been removed.
CAUTION!
Hot coolant can cause injury
X
If necessary, allow the engine to cool down sufficiently to prevent hot gases/liquids
from escaping when the filler cap is opened.
Checking the coolant level
Procedure
• Park the truck securely on a level surface.
• Open the rear bonnet locks and lift off the
rear bonnet, see "Opening the rear panel"
on page 164.
• Check the coolant level on the expansion
vessel (225).
• Fit the rear cover (226) and snap it back into
position.
NOTE
The incorrect coolant can cause
malfunctions
X
To prevent the build up of lime as well as
front and corrosion damage in the
radiator system, and to raise the boiling
point temperature of the coolant, the
cooling circuit must be filled each year
with a mixture of water and anti-freeze
with anti-corrosion additives.
X
Coolant can only be checked and added
by experts.
