WARNING : If the cap with the working valves is opened, there is the rise that it will not close
tightly again afterwards. The excess pressure required in the system will then no
longer build up. Premature boiling occurs and coolant is lost. To prevent
damage to the engine, open this cap only in exceptional circumstances and fit a
new one as soon as possible afterwards.
5.4.2. Draining of coolant
Drain coolant as follows when cooling
system has cooled down;
•
Remove cover from filler neck of
radiator.
•
Remove drain plug in the cylinder
block.
Improper mixing of anti-freeze and
corrosion inhibitors may lead to lime and
corrosion deposits in the engine cooling
system which can jeopardize cooling
efficiency.
In such cases it is necessary to clean the
cooling system at suitable intervals.
