Refill Capacities
NOTICE
Do not use a con
ventional coolant to top-off a cooling
system that is filled with Extended Life Coolant (ELC).
Do not use stan
dard supplemental coolant additive
(SCA).
When using Pe
rkins ELC, do not use standard SCA's
or SCA filters.
ELC Cooling System Cleaning
Note: If the cooling system is already using ELC,
cleaning agents are not required to be used at
the specifi
ed coolant change interval. Cleaning
agents are only required if the system has been
contaminated by the addition of some other type of
coolant o
r by cooling system damage.
Clean water is the only cleaning agent that is required
when ELC i
s drained from the cooling system.
Before the cooling system is filled, the heater control
(if equi
pped) must be set to the hot position. Refer
to the OEM in order to set the heater control. After
the cooling system is drained and the cooling system
is refill
ed, operate the engine until the coolant level
reaches the normal operating temperature and
until the coolant level stabilizes. As needed, add
the coo
lantmixtureinordertofill the system to the
specified level.
Chang
ing to Perkins ELC
To change from heavy-duty antifreeze to the Perkins
ELC, p
erform the following steps:
NOTICE
Care must be taken to ensure that all fluids are
cont
ained during performance of inspection, main-
tenance, testing, adjusting and the repair of the
product. Be prepared to collect the fluidwithsuitable
con
tainers before opening any compartment or dis-
assembling any component containing fluids.
Dis
pose of all fluids according to local regulations and
mandates.
1. Drain the coolant into a suitable container.
2. Dispose of the coolant according to local
regulations.
3. Flush the system with clean water in order to
remove any debris.
4. Use Perkins cleaner to clean the system. Follow
the instruction on the label.
5. Drain the clean
er into a suitable container. Flush
the cooling system with clean water.
6. Fill t he cooli
ng system with clean water and
operate the engine until the engine is warmed to
49° to 66°C (120° to 150°F).
NOTICE
Incorrect or incomplete flushing of the cooling system
can result in damage to copper and other metal com-
ponents.
To avoid damage to the cooling system, make sure to
completel
y flush the cooling system with clear water.
Continue to flush the system until all the signs of the
cleaning agent are gone.
7. Drain the cooling system into a suitable container
and flushthecoolingsystemwithcleanwater.
Note: The cooling system cleaner must be thoroughly
flushed from the cooling system. Cooling system
cleaner
that is left in the system will contaminate the
coolant. The cleaner may also corrode the cooling
system.
8. Repeat Steps 6 and repeat steps 7 until the
system is complete ly clean.
9. FillthecoolingsystemwiththePerkinsPremixed

ELC Cooling System C ontamination
NOTICE
Mixing ELC with other products reduces the effective-
ness of the ELC and shortens the ELC service life.
Use only Perkins Products for premixed or concen-
trate coolants. Failure to follow these recommenda-
tions can result in shortened cooling system compo-
nent life.
ELC cooling systems can withstand contamination to
a maximum of 10 percent of conventional heavy-duty
antifreeze or SCA. If the contamination exceeds 10
percent of the total system capacity, perform ONE of
the following procedures:
•
Drain the cooling system into a suitable container.
Dispose of the coolant according to local
regulations. Flush the system with clean water. Fill
the system with the Perkins ELC.
•
Drain a portion of the cooling system into a suitable
container according to local regulations. Then,
fill the cooling system with premixed ELC. This
procedure should lower the contamination to less
than 10 percent.
