STARTING AND RUNNING
AT FIRST START
When the engine is started for the first time, the maintenance points listed
under ”First start” in the maintenance schedule should be followed,
see page 13.
Since these points are important for the engine to work satisfactorily right
from the start, they are also listed below.
1. Checking oil level (see page 15).
6. Checking coolant (see page 19).
The coolant should contain anti-corrosive to protect the cooling system
from corrosion.
If there is a danger of freezing:
- Only glycol anti-freeze should be used in the coolant as protection
against corrosion. We recommend only nitrite-free glycol anti-freeze
with the following supplier designations:
BASF G48 or BASF D542
- The concentration of glycol should be 30 - 60% by volume depending
on ambient temperature. 30% by volume offers protection down to
-18 °C. See page 19.
- Never top up with water only or glycol only. Lost fluid should always
be replaced with pre-mixed coolant with the same glycol content as the
coolant in the engine. If the concentration of glycol drops, both anti-
freeze and corrosion protection will suffer.
Note! A glycol concentration below 30% by volume will not provide suf-
ficient protection against corrosion. A glycol concentration
greater than 60% will not increase anti-freeze protection and
reduces engine cooling capacity.
If there is no danger of freezing:
- Only Scania Anti-corrosive should be used in the coolant to protect
against corrosion. The correct level of anti-corrosive is 7-12% by vol-
ume and this must never drop below 7% by volume. The inhibitor in
Scania Anti-corrosive is nitrate-free.
- First fill: Fill with Scania Anti-corrosive as indicated on the packaging.
- Never top up with water only or anti-corrosive only. Lost fluid should
always be replaced with pre-mixed coolant:
water + 10% Scania Anti-corrosive by volume.
- Only coolant filter without inhibitor may be used. The use of a coolant
filter increases the life of the coolant and reduces the risk of deposit cor-
rosion.
Coolant should be topped up
when the engine is stopped
after the first start
The recommended glycols
may not be mixed with glycol
which has a nitrite-based
anti-corrosive or with
Scania Anti-corrosive
Scania Anti-corrosive must not
be mixed with glycol.
Mixing or over concentration
can cause sludging
Coolant composition:
If there is a danger of freezing:
at least 30% glycol by volume
Max. 60% glycol by volume
If there is no danger of
freezing:
7-12% by volume
