Maintenance and servicing
5.9.1 Checking the coolant level
Check the coolant level at the sight glass
Fig. 152-7
at regular intervals
and refill as required. Maintenance intervals according to maintenance
plan, see page 167. The sight glass is located on the left-hand side of the
vehicle behind the vehicle cab. The warning symbol
Fig. 152-A
appears in
the indicating device if the coolant level is too low.
Observe the Safety instructions – Cooling system, see page 193.
1. Place the vehicle on a level surface and hold it with the parking brake.
Switch the engine off and pull out the ignition key. Allow the engine to
cool down.
2. Check the coolant level.
With the engine cooled down, the coolant must be in the middle of the
sight glass
Fig. 152-7
. If the engine is warm, it might also be above the
middle.
3. If no coolant can be seen in the sight glass or the warning
symbol
Fig. 152-A
lights up in the indicating device, coolant must be
topped up.
5.9.2 Topping up the coolant
Observe the Safety instructions – Cooling system, see page 193.
1. Place the vehicle on a level surface and secure it with the parking
brake.
2. Raise the dirt hopper and place it on the safety strut, see page 222.
3. Switch the engine off and pull out the ignition key. Allow the engine to
cool down. Observe the safety instructions, see page 193.
4. Cover the filler cap
Fig. 153-A
with a cloth.
5. Gradually unscrew the filler cap carefully up to the stop. Wait until the
pressure is even. Press down the filler cap and open completely.
6. Coolant specification, see page 179.
Slowly top up coolant. If the radiator has been topped up to the middle
of the sight glass, lock the filler cap again.
7. Turn the rotary switch
Fig. 153-57
up to the stop towards red (warm).
8. Run the engine with increased idle speed for a few minutes.
9. Turn off the engine and check the coolant level again and top up if
necessary; observe expansion of the coolant at high temperatures.

Note
The coolant prevents frost and corrosion damage and lime
deposits and also increases the boiling point of the water. For
these reasons, the cooling system must be filled with coolant
additive the whole year round. Especially in countries with a
tropical climate, the coolant with its higher boiling point con-
tributes to operational safety when the engine is under high
load.
