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 27.
Since the points are important for satisfactory operation of the engine right
from the outset, they are also listed below.
1. Checking the oil level (see page 29).
6. Checking the coolant level (see page 33).
The coolant should contain anti-corrosive to protect the cooling system
from corrosion.
If there is a danger of freezing:
- Only anti-freeze glycol should be used in the coolant as protection
against corrosion. We recommend only nitrite-free anti-freeze glycol
with the following supplier designations:
BASF G48 or BASF D542
- The concentration of glycol should be 30 - 60% by volume depending
on the ambient temperature. 30% glycol by volume provides anti-freeze
protection down to -16°C. See page 33.
- Never top up with only water or only glycol. Fluid losses must always
be replaced with pre-mixed coolant having the same glycol
concentration as that in the engine. If the glycol content drops, both
anti-freeze protection and protection against corrosion are impaired.
Note: A glycol concentration below 30% by volume will not provide
sufficient protection against corrosion. Glycol concentrations
higher than 60% do not improve anti-freeze protection and have
a negative effect on engine cooling capacity.
Coolant composition:
If there is a danger of freezing:
minimum
30% glycol by volume
maximum
60% glycol by volume
If there is no danger of freezing:
7-12% by volume
Scania Corrosion Inhibitor
(no glycol)
The recommended glycols
should not be mixed with
glycol containing nitrite-based
corrosion inhibitor.
Ethylene glycol and
corrosion inhibitor
are toxic if ingested.
Avoid contact with the skin.
