Coolant
During operation the system is pressurised.
The temp erature ma y therefore rise briefly
to ov er 100 °C.
The glycol-ba sed coolant provides
exc ellent 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 b e changed.
Certain a ntifreeze can lea d to engine
damage. We therefore strongly
recommend the use of antifreeze that has
been approved by Vaux hall.
Anti-freeze is a da nger to health; it must
therefore be kept in the original
container and out of the reach of
children.
Anti -freeze a nd corrosion prot ect ion
Before the sta rt of the cold weather season,
have the coolant checked for correct
concentration. We recommend that you
consult a Vaux ha ll Authorised Repairer.
The amount of a ntifreeze must provide
protec tion up to approx. – 28 °C . If the
antifreeze concentra tion is too low, this
reduc es protection from freezing and
corrosion. Top up antifreeze if necessary .
If c oolant loss is topped up with wa ter,
have concentration checked and a dd anti-
freeze if necessary.
