Coolant

During operation the sy stem is pressurized.
The temp erature may therefore rise to ov er
100 °C .
The a nti-freeze provides excellent
corrosion protection for the c ooling and
heating system , as well as freez e
protection down to -28 °C.
Certain types of a nti-freeze can lea d to
engine dama ge. We therefore strongly
recom mend the use of anti-freeze that has
been app rov ed b y Vauxhall.

Warning
Anti-freeze is a danger to health; it must
therefore be kept in the original container
and out of the rea ch of children.
Freeze prot ect ion and corr osion
protection
Before the start of the cold weather season,
ha ve the coolant checked for correc t
concentration. We rec om mend that you
consult y our Va ux ha ll Authorised Repairer.
The amount of antifreez e m ust provide
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 top ped up with water,
ha ve a nti-freeze concentration checked
and more anti-freeze a dded as necessary.
C ool ant level
Hard ly any losses occur since the c ooling
system is sea led a nd it is thus rarely
nec essary to top up the coola nt.
The coolant level in the expansion ta nk
should be slightly abov e the MIN mark
when the system is cold. It rises at eng ine
operating temperature and drops a gain
when the engine cools down. If the level
falls below the MIN mark, the coolant
should be replenished to a little over the
ma rk .
