Coolant Level; Coolant Temperature - Vauxhall Astra Owner's Manual

Coola nt Lev el
Hardly any losses occur since the cooling
system is sealed and it is thus rarely
necessary to top up the c oolant.
The c oolant in the compensation tank
should b e slightly above the mark
KALT / C OLD with the cooling sy stem cold .
It rises when the engine is warm and falls
again as it c ools. If it drops below the
marking in this case, it should be topped up
to a level just abov e the marking.
Allow engine to cool d ow n before
removing coola nt filler ca p. Remove filler
cap carefully so that p ressure can
escape slowly, otherwise there is a risk of
scalding.
Top up anti-freeze. I f no anti-freeze is
available, top up w ith c lean tap water. If
tap water is unav ailable, distilled water
can be used.
After topping up w ith tap or distilled water,
ha ve the anti-freez e concentration
checked, a nd anti-freeze added if
necessary. H ave the cause of the coolant
loss remedied. We recommend that you
consult a Vauxhall Authorised Repairer.
When closing, tighten coola nt filler cap as
fa r 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 system is pressurised.
The tem perature may therefore rise to ov er
100 ° C.
If the temp erature g auge enters the red
zone, check the coolant level immediately.
