Do not remove the cap from the expansion bottle
while the engine is hot.
Take care when carrying out a repair under the bon-

without warning.
Do not open the bleed screw(s) with the engine run-
ning.
WARNING
Before the operation, protect the electrical accesso-
ries to prevent any risk of short circuiting and pro-
tect the belts to avoid damaging them.

The coolant helps to keep the engine running pro-
perly (heat exchange).
The system does not operate using pure water.
