Coolant - Vauxhall Corsa 2007 Owner's Manual

Coolant

The glycol-based coolant provides
excellent corrosion protection for the
heating and cooling systems as well as
anti-freeze protection down to –28 °C. It
remains in the cooling system throughout
the year and need not be changed.
Use of certain anti-freezes can lead to
engine damage. We therefore recommend
that you only use approved anti-freezes.

Warning
Anti-freeze is a danger to health; it must
therefore be kept in the original container
and out of the reach of children.

Anti-freeze and corrosion protection
Have the concentration of the radiator
contents tested by a workshop before
winter starts. The amount of anti-freeze
must provide protection down to approx.
–28 °C. A lower anti-freeze concentration
will reduce the amount of protection from
frost and corrosion. Add anti-freeze if
necessary.
If coolant loss is topped up with water,
have concentration checked and add
anti-freeze if necessary.
Service, maintenance
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 on the expansion tank
with a cold cooling system.

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.
