Diesel fuel filter
On each engine oil change, have the fuel
filter checked for any water residue by a
workshop.
For engines

Z 19 DT, Z 19 DTL and
Z 19 DTH, control indicator

illuminates
if there is water in the diesel fuel filter.
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
The –glycol-based – coolant provides
excellent corrosion protection for the
heating and cooling systems as well as
antifreeze protection down to approx.
-28 °C. It remains in the cooling system
throughout the year and need not be
changed.
Use of certain antifreezes can lead to
engine damage. We therefore recommend
that you use only approved antifreezes.
Antifreeze and corrosion protection
Before the start of winter, have a workshop
check the antifreeze protection. The
antifreeze level must guarantee protection
to approx. -28 °C. Insufficient antifreeze
will reduce the frost protection level and
the corrosion protection. If necessary add
antifreeze.
If coolant loss is topped up with water,
have concentration checked and add
antifreeze if necessary.

Warning
Antifreeze is a danger to health; it must
therefore be kept in the original container
and out of the reach of children.
