Lubrication system
26. Fit a new O-ring in the cover.
27. Refit the cover and tighten the lock nut.
Tightening torque 20 Nm (15 lb-ft).
IMPORTANT!
To reduce the risk of oil leakage it is important to
tighten the cover to the correct tightening torque.
Operational testing of the
centrifugal oil cleaner
Operational testing need only be carried out if it
is suspected that the centrifugal oil cleaner is
malfunctioning. For example, if the dirt deposit
is abnormally small given the distance driven.
The rotor rotates very fast and should continue to
turn when the engine has stopped.
1. Run the engine until it reaches normal oper-
ating temperature.
2. Switch off the engine and listen for the sound
from the rotor. Use your hand to feel if the
filter housing is vibrating.
3. If the filter housing is not vibrating, disman-
tle and check the centrifugal oil cleaner.

- Drain the lubrication system as follows:
2. Detach the oil filter cover with specified tool.
See illustration.
3. Allow the system to drain for approximately
2 minutes.
4. Renew the oil filter.
5. Refit the oil filter cover. Tightening torque
for cover: 25 Nm.
6. Clean the area around the centrifugal oil
cleaner.
Environment
Use a waste oil trolley when draining the centrif-
ugal oil cleaner.
WARNING!
Wear protective gloves and goggles. When the
bottom cover is detached, a small amount of oil
will always run out.
7. Unscrew the bottom cover of the centrifugal
oil cleaner 2 turns without removing the cov-
er. See illustration. Start from a mark on the
cover to see the number of turns.
8. Drain the centrifugal oil cleaner for approxi-
mately two minutes.
33

9. Remove the bottom cover together with the
rotor.
10. Remove the rotor by pulling it straight up
from the cover. See illustration.
IMPORTANT!
Lubricate the threads on the cover and O-rings
with engine oil before they are refitted.
11. Renew the uppermost black O-ring.
12. Renew the 2 lower green O-rings.

IMPORTANT!
Clean the centrifugal oil cleaner at the same time
as you change the oil filter. Otherwise, the oil fil-
ter will be blocked and resistance in the filter will
increase. If this happens, an overflow valve in
the filter retainer opens and lets the oil pass with-
out being filtered.
1. Unscrew the filter cover using the socket.
IMPORTANT!
Do not use an adjustable spanner or other open
tool, as there is a risk of damaging the filter cov-
er.
2. Lift out the filter housing cover with filter el-
ement. The filter housing will drain automat-
ically once the filter has been removed.
3. Detach the old filter from the cover by hold-
ing the cover and carefully tapping the entire
filter element against something hard. Re-
member that there will be oil splashes.
4. Fit the new filter and tighten the filter cover
to 25 Nm (18 lb/ft).

system is cleaned: every 6,000 hours or at least
every five years. See Changing the coolant and
cleaning the cooling system.
The coolant recommended by Scania is a mix-
ture of water with antifreeze (ethylene glycol)
and corrosion protection. The coolant has several
characteristics which are important for the oper-
ation of the cooling system:
• Corrosion protection
• Antifreeze
• Increases the boiling point
The coolant should always contain 35-55% by
volume of antifreeze and corrosion inhibitor so
that the coolant properties ensure that the coolant
works correctly.
Note:
Too high a dose of antifreeze and corrosion in-
hibitor will increase the amount of sludge and
blockages accumulating in the radiator. Too low
a concentration can lead to corrosion of the cool-
ing system and ice formation at low tempera-
tures.
39
Cooling system
Antifreeze and corrosion protection
should be used in warm countries where there is
no risk of freezing in the cooling system.
The antifreeze and corrosion protection used in
Scania engines should be of the antifreeze (eth-
ylene glycol) and corrosion protection type.

ed with oil or fuel, it must not be reused.
If the coolant starts to freeze, the water in the
coolant starts to crystallise and the ethylene gly-
col content in the coolant increases. If freezing
produces a great increase in the amount of ice,
circulation problems could arise. There is no risk
of damage by freezing if the content of Scania
antifreeze and corrosion inhibitor, or an equiva-
lent mixture of a similar product, is at least 35%
by volume.
Minimal ice formation in the coolant sometimes
causes minor problems without any risk of dam-
age. For example, the auxiliary heater may not
work for up to one hour after the engine has been
started.

Checking coolant level
WARNING!
Do not open the coolant filler cap in the expan-
sion tank if the engine is hot. Hot coolant and
steam may spray out and cause burns.
If the cap has to be opened do it slowly to release
the pressure before removing the cap. Wear pro-
tective gloves as the coolant is still very hot.
IMPORTANT!
It is not permissible to top up large amounts of
coolant via the expansion tank. Filling via the ex-
pansion tank leads to air locks in the cooling sys-
tem which can lead to e.g. cavitation damage to
the coolant pump shaft seal. If a large amount of
coolant needs to be added, follow the instruc-
tions in the section Filling coolant.
Only pour pre-mixed coolant into the cooling
system.
The following instructions apply to Scania ex-
pansion tanks. For other types of expansion
tanks, follow the manufacturer's instructions.
1. Open the expansion tank cap and check the
coolant level.
- The right coolant level on a cold engine is
even with the lower edge of the filler neck.
- The right coolant level on a hot engine is
approximately 25 mm (1 in) over the low-
er edge of the filler neck.
2. Top up with coolant as necessary.

• If ice forms in the coolant, there are disrup-

IMPORTANT!
Use only pure fresh water that is free of particles,
sludge and other impurities.
1. Pour a small amount of coolant into a con-
tainer and check that the coolant is pure and
clear.
2. Change the coolant if it is contaminated or
