NOTICE
When any servicing or repair of the engine cooling
system is performed the procedure must be per-
formed with the engine on level ground. This will allow
you to accurately check the coolant level. This will al-
so help in avoiding the risk of introducing an air lock
into the coolant system.
1.
Slowly loosen the cooling system filler cap in order
to relieve the pressure. Remove the cooling
system filler cap.
Note:
Always discard drained fluids according to local
regulations.
2.
If necessary, drain some coolant from the cooling
system into a suitable container in order to allow
space for the extra SCA.
3.
Add the correct amount of SCA. Refer to the
Operation and Maintenance Manual, “Refill
Capacities and Recommendations” for more
information on SCA requirements.
4.
Clean the cooling system filler cap and inspect the
gasket. If the gasket is damaged, discard the old
filler cap and install a new filler cap. If the gasket is
not damaged, use a suitable pressurizing pump in
order to pressure test the filler cap. The correct
pressure is stamped on the face of the filler cap. If
the filler cap does not retain the correct pressure,
install a new filler cap.

Crankcase Breather (Canister)
- Replace
Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
NOTICE
Ensure that the engine is stopped before any servic-
ing or repair is performed.
The crankcase breather is a very important
component in order to keep your engine emissions
compliant.
• The filter element within the crankcase breather
must be serviced at the prescribed service interval.
• The correct filter element must be installed before
the engine is operated.
• The installation of the filter element is very
important.
• The quality of the filter element that is installed is
very important.
• The filter element protects the engine from
excessive quantities of oil from entering the
induction system. The filter element also protects
the engine aftertreatment system.
Note:
Excessive quantities of oil that enter the
induction system of the engine can rapidly increase
the engine speed without control.
