5. Clean the cooli
ng 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
,useasuitablepressurizingpump
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.
6. Start the en
gine. Inspect the cooling system for
leaks and for correct operating temperature.

NOTICE
Care must be taken to ensure that fluids are contained
during p
erformance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to
collect the fluid with suitable containers before open-
ing any c
ompartment or disassembling any compo-
nent containing fluids.
Dispos
eofallfluids according to Local regulations and
mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Clean the cooling system and flush the cooling
syst
em before the recommended maintenance
interval if the following conditions exist:
•
The
engine overheats frequently.
•
Foaming of the coolant is observed.
•
The oil has entered the cooling system and the
coolant is contaminated.
•
The fuel has entered the cooling system and the
coolant is contaminated.
Note: When the cooling system is cleaned, only
clean water is needed when the ELC is drained and
r
eplaced.
Note: Inspect the water pump and the water
t
emperature regulator after the cooling system
has been drained. This inspection can be a good
opportunity to replace the water pump, the water
temperature regulator, and the hoses, if necessary.
NOTICE
When any servi
cing or repair of the engine cooling
system is performed the procedure must be performed
with the engine on level ground. Level ground will al-
low you to accu
rately check the coolant level. This
check will also help in avoiding the risk of introduc-
ing an air lock into the coolant system.
Drain
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the en
gine and wait until the cooling sy stem
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the pres-
sure.
1. Stop the engine and allow the engine to cool.
Loosen t
he cooling system filler cap slowly in
order to relieve any pressure. Remove the cooling
system filler cap.
