Starting and running
First start
When the engine is started for the first time, the inspection points listed under
"First start" in the inspection schedule should be followed, see page 25.
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 27.
8. Checking the coolant, see page 33.
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. Scania recommends 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 33.
- 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
antifreeze 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 antifreeze protection and have
an adverse 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 concentration of corrosion
inhibitor 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 filters 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:
min 30% glycol by volume
max 60% glycol by volume
If there is no danger of freezing:
8-12% by volume
Scania Corrosion Inhibitor
(no glycol)
Ethylene glycol and corrosion
inhibitor can be fatal if
ingested.
Avoid contact with the skin.
Overdosing with
Scania
Corrosion Inhibitor
and mixing
with glycol
can cause sludge to
be formed.
If a coolant filter has been fitted
it must not contain inhibitor.
