Maintenance
5.5 Engine cooling system
The oil/water radiator is located in the engine compartment, behind the engine. It cools the
diesel engine and the hydraulic oil of the drive and work hydraulics.
The expansion tank for the coolant is located in the engine compartment next to the
toolbox.
Checking/filling up coolant
NOTICE: Improperly maintaining the cooling system may cause engine damage.
z
Dirt on the radiator fins reduces the radiator's heat dissipation capacity.
f Clean the outside of the radiator at regular intervals. Use oil-free
compressed air (2 bar max.) to clean. Maintain a certain distance from
the radiator to avoid damage to the radiator fins. Refer to the
maintenance plans in the appendix for the cleaning intervals.
f In dusty or dirty work conditions, clean more frequently than indicated
in the maintenance plans.
z
An insufficient coolant level reduces the heat dissipation capacity as well
and may lead to engine damage:
f Check the coolant level at regular intervals. Refer to the maintenance
plans for the recommended intervals.
f If coolant must be added frequently, check the cooling system for leaks
and/or contact your dealer.
f Never add cold water/coolant if the engine is warm.
f After filling the expansion tank, make a test run with the engine and
check the coolant level again after switching off the engine.
z
The use of the wrong coolant may destroy the engine and the radiator.
f Add enough antifreeze compound to the coolant—but never more than
50 %. If possible use brand-name antifreeze compounds with
anticorrosion additives.
f Observe the coolant compound table – see chapter 6.12 “Coolant
compound table” on page 6-7.
f Do not use radiator cleaning compounds if an antifreeze compound
has been added to the coolant—otherwise this causes sludge to form,
which may damage the engine.
Environment
Use a suitable container to collect the coolant as it drains and dispose of it in
an environmentally friendly manner!
