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 in the compensation tank
should be slightly above the mark
KALT / COLD with the cooling system cold.
It rises when the engine is warm and falls
again as it cools. If it drops below the
marking in this case, it should be topped up
to a level just above the marking.

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.
Top up anti-freeze. If no anti-freeze 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.
To close, position the cap and screw it into
place.
