Freeze p rotection and corrosion
prot ect ion
Before the start of the cold weather season,
have the coolant checked with a calibrated
hydrometer for correct concentration b y a
workshop. We recommend your Vauxhall
Approved Repairer. The anti-freez e
content must guarantee freeze protection
down to app rox imately -30 ° C. An
insufficient concentration will reduce freeze
and corrosion protection. Add anti-freeze if
necessary.
If coolant loss is topped up with water,
have anti-freez e concentration chec ked
and more anti-freeze added as necessary.
Coolant lev el
Hardly a ny losses occur since the cooling
sy stem is sealed and it is thus rarely
necessary to top up the coolant.
The coolant lev el in the exp ansion tank
should be level with the centre seam when
the system is cold. It rises at eng ine
op erating temperature and drops again
when the engine cools down. I f the lev el
fa lls below the centre seam, the coolant
should be replenished .
Remove filler cap carefully so that pressure
can esca pe slowly . Top up a nti-freeze. If no
anti-freeze is available, top up with clean
tap water.
After topping up with water, have the
concentration check ed, and anti-freeze
add ed if necessary, b y a w ork shop. We
recommend your Vaux hall Ap prov ed
Repairer.
When closing , tighten coolant filler ca p as
far as it will go.
C ool ant temp era ture
For physical reasons, the engine
temperature gauge shows the coolant
temperature only if the coolant level is
adequate.
During operation the sy stem is pressurized.
The tem perature may therefore rise to ov er
100 ° C.
If the temp erature g auge flashes, check
the coola nt level immediately .
