Coola nt level
Hardly any losses occur since the cooling
system is sealed and it is thus rarely
necessary to top up the c oolant.
The c oolant level in the expansion tank
should b e slightly above the KALT/COLD
mark when the sy stem is cold. It rises a t
engine operating temperature and drops
again when the engine cools down. If the
lev el falls below the m ark, the coola nt
should b e topped up to a little over the
mark.
Allow engine to cool d ow n before
removing coola nt filler ca p. Remove filler
cap carefully so that p ressure can
escape slowly, otherwise there is a risk of
scalding.
Top up anti-freeze. I f no anti-freeze is
available, top up w ith c lean tap water. If
tap water is unav ailable, distilled water
can be used.
After topping up w ith tap or distilled water,
ha ve the anti-freez e concentration
checked, a nd anti-freeze added if
necessary. H ave the cause of the coolant
loss remedied. We recommend that you
consult a Vauxhall Authorised Repairer.
When closing, tighten coola nt filler cap as
fa r as it will go.
C ool ant temp era ture
For physical reasons, the engine
temperature gauge shows the coolant
temperature only if the coolant level is
adequate.
During operation the system is pressurised.
The temperature ma y therefore rise to
over 100 °C .
If the temp erature g auge enters the right-
hand (w arning) zone or control indicator W
lights up, chec k the c oolant level
imm ediately.
z Coolant level too low:
Top up coolant. Pay strict attention to
the instructions given under "Anti-freeze
and corrosion protection" a nd "Coolant
level". Have the cause of coolant loss
remedied . We recommend that you
consult a Vauxhall Authorised Repairer.
z Coolant level O K:
Have the c ause of inc reased coolant
temperature remed ied. Contact a
workshop. We rec om mend that you
consult a Vauxhall Authorised Repairer.
