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

184 Maintenance, Service Plan

Diesel fuel filter

Check the fuel filter for any water residue
during each engine oil change.
We recommend that you consult your
Vauxhall Authorised Repairer.
Illumination of A indicates water in the
diesel fuel filter 3.
Have diesel 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 approx.
–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 using a calibrated
hydrometer. We recommend that you
consult your Vauxhall Authorised Repairer.
The anti-freeze content must guarantee
frost protection down to approx. –28 °C. An
insufficient concentration will reduce frost
and corrosion protection. Add anti-freeze if
necessary.
If coolant loss is topped up with water,
have concentration checked and add anti-
freeze if necessary.
