Diesel Fuel Filter; Coolant - Vauxhall ASTRA Owner's Manual

294 Maintenance, inspection system

Diesel fuel filter

Check fuel filter for any water residue when
each engine oil change takes place. We
recommend that you consult your Vauxhall
Authorised Repairer.
Illumination of A indicates water in the
fuel filter 3.
Have fuel filter checked at shorter intervals
if the vehicle is subjected to extreme
operating conditions such as high humidity
(primarily in coastal areas), extremely high
or low outside temperatures and
substantially varying daytime and night-
time temperatures.

Coolant

During operation the system is pressurised.
The temperature may therefore rise briefly
to over 100 °C.
The glycol-based coolant provides
excellent 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 be changed.
Use of certain anti-freezes can lead to
engine damage. We therefore recommend
that you use anti-freezes that have 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.

Anti-freeze 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 anti-freeze must provide
protection up to approx. –28 °C. If the anti-
freeze concentration is too low, this
reduces protection from freezing and
corrosion. Top up anti-freeze if necessary.
If coolant loss is topped up with water,
have concentration checked and add anti-
freeze if necessary.
