Washer Fluid - Vauxhall Astra Owner's Manual

218 Vehicle care
Coolant level
Caution
Too low a coolant level can cause
engine damage.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.

Washer fluid

Fill with clean water mixed with a
suitable quantity of windscreen
washer fluid which contains
antifreeze. For the correct mixing ratio
refer to the washer fluid container.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
