Coolant level
Hardly any losses occur since the cooling
system is sealed and it is thus rarely
necessary to top up the coolant.
The coolant should be a little above the
KALT/COLD mark in the expansion tank
with a cold cooling system. The coolant
level can also be read off from the outside
of the expansion tank.
When the engine is at operating
temperature, coolant level rises. It falls
again when the system cools. If it falls
below the KALT/COLD mark when the
system is cold, top up to the mark.
Top up antifreeze. If no antifreeze is
available, top up with clean tap water. If
tap water is unavailable, distilled water
can be used.
After topping up with drinking water or
distilled water, check the anti-freeze level
and add anti-freeze if required. Eliminate
the cause of the coolant loss. We
recommend your Vauxhall Authorised
Repairer.
Too low a coolant level can cause engine
damage.
To close, position the cap and screw it into
place.
Coolant temperature
Control indicator W illuminates when
coolant temperature is too high. Check
coolant level immediately:
z Coolant level low:
Top up coolant. Pay attention to the
instructions given under "Antifreeze and
corrosion protection" and "Coolant
level". Have the cause of coolant loss
remedied. We recommend that you
consult your Vauxhall Authorised
Repairer.
z Coolant level OK:
Have the cause of increased coolant
temperature remedied. Consult a
workshop. We recommend your
Vauxhall Authorised Repairer.
9 Warning
Allow engine to cool down before
removing coolant filler cap. Remove filler
cap carefully so that pressure can escape
slowly, otherwise there is a risk of
scalding.
