Starting and driving
First start
When the engine is started for the first time, carry out the maintenance points
listed under "First start" in the maintenance schedule; see page 31.
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 33.
6. Checking the coolant; see page 34.
The coolant must contain corrosion inhibitor to protect the cooling
system from corrosion.
If there is a danger of freezing:
- Only antifreeze glycol should be used in the coolant as protection
against corrosion. We recommend only nitrite-free antifreeze glycols
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 37.
- Never top up with water alone or glycol alone! 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.
If there is no danger of freezing:
- Only Scania Corrosion Inhibitor should be used in the coolant as
protection against corrosion. The correct corrosion inhibitor content is
8-12% by volume, and this must never drop below 8% by volume. The
inhibitor in Scania Corrosion Inhibitor is free of nitrites.
- First filling: Fill up the system with water + 10% by volume Scania
Corrosion Inhibitor. Use drinking water with a pH of 6-9.
- Never top up with water alone or corrosion inhibitor alone!
Fluid losses must always be replaced with pre-mixed coolant: water
+ 10% Scania Corrosion Inhibitor by volume.
Coolant filter (not standard equipment)
Only coolant without inhibitor may be used. The use of coolant filters
increases the life of the coolant and reduces the risk of deposit corrosion.
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:
8-12% by volume
Scania Corrosion Inhibitor
(no glycol)
The recommended glycols must
not be mixed with glycol
containing nitrite-based
corrosion inhibitor.
Ethylene glycol and corrosion
inhibitor can be fatal if
imbibed.
Avoid contact with the skin.
Overdosing with Scania
Corrosion Protection and mixing
with glycol can cause sludge to
form.
If a coolant filter has been fitted
it must not contain inhibitor.
