Maintenance
4.4 Cooling systems
The combined charge air/oil/radiator is located on the right vehicle side
behind the engine. It cools both the charge air for the turbocharger and the
diesel engine coolant as well as the hydraulic oil of the drive and work
hydraulics.
The expansion tank for the coolant is located on the right behind the cab.
4.4.1
Specific safety instructions
Danger!
Never open the radiator and never drain coolant if the engine is
warm, since the cooling system is under high pressure –
Risk of burns!
Wait at least 10 minutes after switching off the engine!
Wear protective gloves and clothing
Always start by actuating the safety valve in the cap of the
expansion tank. To do this: Open the cap to the first notch
and allow the pressure to escape.
•
The coolant agent and the coolant are detrimental to health! Therefore,
store the coolant agent in the original container especially safe from
children!
•
Dirt on the cooling ribs reduces the radiator’s heat dissipation capacity!
Therefore:
Clean the outside of the radiator at regular intervals. Cleaning inter-
vals (see page 4-63)
In dusty or dirty work conditions, clean more frequently than indicated
in the maintenance plans
•
An insufficient coolant level reduces the heat dissipation capacity as
well, and can lead to engine damage! Therefore:
Check the coolant level at regular intervals (see page 4-63).
If coolant must be added frequently, check the cooling system for lea-
kage and/or contact your authorised workshop!
Never fill in cold water/coolant if the engine is warm!
After filling the radiator, test run the engine and check the coolant
level again after switching off the engine
•
The use of the wrong coolant can severely damage the engine and
radiator. Therefore:
Use only
G 12 plus
and/or an additive with the specification TL-VW
774 F as a coolant additive, since it already contains an anticorrosion
agent (see page 4-62)
Do not use radiator cleaning compounds if an antifreeze compound
has been added to the coolant – otherwise this causes sludge to form,
which can damage the engine
Environment!
Use a suitable container to collect the any spilt coolant and dis-
pose of it according to local or national environment protection
regulations!
