Anti-Freeze And Corrosion Protection; Coolant Level; Coolant Temperature - Vauxhall Corsa Owner's Manual

Anti-freeze and corrosion protection

Have concentration of radiator contents
checked before start of Winter. We
recommend that you consult a Vauxhall
Authorised Repairer. The amount of
antifreeze must provide protection from
freezing up to approx. –28 °C. Low
antifreeze concentration reduces the
antifreeze and anticorrosion effect. Add
antifreeze if necessary.
If coolant loss is topped up with water,
have concentration checked and add anti-
freeze if necessary.

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.
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 tap or distilled water,
have the anti-freeze concentration
checked, and anti-freeze added if
necessary. Have the cause of the coolant
loss remedied. We recommend that you
consult a Vauxhall Authorised Repairer.
When closing, tighten coolant filler cap as
far as it will go.

Coolant temperature

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 may therefore rise to
over 100 °C.
If the temperature gauge enters the red
zone, check the coolant level immediately.
z Coolant level too low:
Top up coolant. Pay strict attention to
the instructions given under "Anti-freeze
and corrosion protection" and "Coolant
level". Have the cause of coolant loss
remedied. We recommend that you
consult a Vauxhall Authorised Repairer.
z Coolant level OK:
Have the cause of the increased coolant
temperature remedied. We recommend
that you consult a Vauxhall Authorised
Repairer.
