5.3 DRAINING AND FILLING/BLEEDING, 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.
XF/XE ENGINE
Draining the cooling system
1. Turn the heater control knob to the
”warmest” 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 tap (A) and the radiator
via the drain plug (B). If an integrated
retarder is used, remove the coolant drain
plug of the heat exchanger.
5. Flush the cooling system.
6. Close the drain tap (A) and fit the drain plug
(B).
