6. DRAINING AND FILLING

6.1 DRAINING AND FILLING COOLANT

}

In order to avoid damaging the 
cylinder block, do not top up a warm 
engine with cold coolant.
Coolant is a toxic fluid and must be 
handled with care.
Protect skin and eyes.
Coolant is harmful to the 
environment; after use, it should be 
processed as industrial chemical 
waste.
When the coolant is hot, there is 
overpressure in the cooling system.
When removing the filler cap, allow 
the overpressure to escape by first 
loosening the filler cap one turn. 

Draining the cooling system
1.

Turn the heater control knob to the maximum 
"hot" temperature setting. 

2.

Remove the cooling system filler cap.

3.

Collect the coolant. To do this, place a 
suitable container under the drain point.

4.

Drain the cooling system at the radiator via 
drain plug B. 

5.

Flush the cooling system.

6.

Fit drain plug B.

Filling/venting the cooling system
1.

Turn the heater temperature control knob in 
the cab to the maximum "hot" setting.

2.

Fill the cooling system with the specified 
coolant up to the fill opening of the expansion 
tank.

3.

Start the engine and continue to top up the 
cooling system.

4.

The cooling system is auto-venting. Venting 
will be audible during topping up. Continue 
topping up until venting is no longer audible.

5.

Close the cooling system and allow the 
engine to warm up until the thermostat has 
opened. 

6.

Stop the engine and check the coolant level 
on the transparent rear side of the expansion 
tank; add more coolant if necessary.

3.

Turn the heater temperature control knob in 
the cab to the maximum "hot" setting.

4.

Switch on the heater fan.

5.

Set the rocker switch on the thermostat in the 
cab to position 1.

Note:
Combustion will start after approximately 
one minute.

6.

Allow the cab heater to operate for 
approximately 15 minutes.

7.

Check the coolant level again; top up with 
coolant if necessary.
