5.3 DRAINING, FILLING AND BLEEDING THE COOLING SYSTEM
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. As a result, the
heater valve will be fully opened.
2. Remove the cooling system filler cap.
3. Collect the coolant. Position suitable
containers under the drain points.
4. Drain the cooling system at the cylinder
block via the drain cock (A) and the radiator
via the drain plug (B).
5. Flush the cooling system.
6. Close the drain tap (A) and fit the drain
plug (B).
Filling and bleeding cooling system
Note:
The cooling system is auto-bleeding.
1. Turn the heater temperature control knob in
the cab to the maximum "hot" setting.
2. Fill the cooling system with the specified
coolant.
3. Run the engine for several minutes.
4. Ensure that the air bleed pipe from the
thermostat housing to the header tank is not
twisted or pinched.
5. Check the coolant level, and top up with
coolant if necessary.
