Coolant
During operation, the system is
pressurized. The temperature may
therefore rise to over 100 °C.
The antifre ez e provides ex cellent corrosion
protection for the cooling and heating
system, as well as freeze protection down
to -28 °C.
Certain types of antifreeze can lead to
engine damage. We therefore strongly
recommend the use of antifreeze that has
been approved by Vauxhall.
Antifreeze and corrosion protection
Before the start of the cold weather season,
have the coolant checked for correc t
concentration by a workshop. The a mount
of antifreeze m ust provid e protection down
to approx. –28 °C. If the antifreeze
concentration is too low, this reduces
protection from freezing and corrosion.
Top up antifreeze if necessary.
If coolant loss is topped up with
demineralised water, have antifreeze
concentration checked and m ore
antifreeze added as necessary.

C ool ant level
Hardly any losses occur since the cooling
system is sealed and it is thus rarely
necessary to top up the coolant.
The coolant level in the expansion ta nk
should be between the MIN and MAX
marks when the system is cold.

Antifreeze is a danger to health: it must
the refore be kept in the original container
and out of the reach of children.
