5.3 DRAINING AND FILLING COOLANT
In order to avoid damaging the
engine 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 temperature control knob to
the maximum "hot" 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 the 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 self-bleeding. 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.
