Coolant - Vauxhall VIVARO Owner's Manual

Coolant

During operation the system is pressurized.
The temperature may therefore rise to over
100 °C.
The anti-freeze provides excellent
corrosion protection for the cooling and
heating system, as well as freeze
protection down to -28 °C.
Certain types of anti-freeze can lead to
engine damage. We therefore strongly
recommend the use of anti-freeze that has
been approved by Vauxhall.

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

Freeze protection and corrosion
protection
Before the start of the cold weather season,
have the coolant checked for correct
concentration. We recommend that you
consult your Vauxhall Authorised Repairer.
The amount of antifreeze must provide
protection up to approx. –28 °C. If the
antifreeze concentration is too low, this
reduces protection from freezing and
corrosion. Top up antifreeze if necessary.
If coolant loss is topped up with water,
have anti-freeze concentration checked
and more anti-freeze added as 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 level in the expansion tank
should be slightly above the MIN mark
when the system is cold. It rises at engine
operating temperature and drops again
when the engine cools down. If the level
falls below the MIN mark, the coolant
should be replenished to a little over the
mark.
