The anti-corrosion package for ELC is different from
the anti-corrosion package for other coolants. ELC
is an ethylene
glycol base coolant. However, ELC
contains organic corrosion inhibitors and antifoam
agents with low amounts of nitrite. Perkins ELC
has been form
ulated with the correct amount of
these additives in order to provide superior corrosion
protection for all metals in engine cooling systems.
ELC extends the service life of the coolant to 12000
service hours or six years. ELC does not require
a frequent ad
dition of a Supplemental Coolant
Additive (SCA). An Extender is the only additional
maintenance that is needed at 6000 service hours or
onehalfoft
he ELC service life.
ELC is available in a 1:1 premixed cooling solution
with disti
lled water. The Premixed ELC provides
freeze protection to −36 °C (−33 °F). Th e Premixed
ELC is recommended for the initial fill of the cooling
system. Th
e Premixed ELC is also recommended for
topping off the cooling system.
ELC Concen
trate is also available. ELC Concentrate
canbeusedtolowerthefreezingpointto−51 °C
(−60 °F) for arctic conditions.
Containers of several sizes are available. Consult
your Perkins dealer or your Perkins distributor for the
part numb
ers.

Correct additions to th e Extended Life

NOTICE
Use only Perkins products for pre-mixed or concen-
trated coolants.
Use only Perkins Extender with Extended Life
Coolant.
Mixing Extended Life Coolant with other products re-
duces the Extended Life Coolant service life. Failure to
follow the recommendations can reduce cooling sys-
tem components life unless appropriate corrective ac-
tion is performed.
In order
to maintain the correct balance between
the antifreeze and the additives, you must maintain
the recommended concentration of Extended Life
Coolan
t (ELC). Lowering the proportion of antifreeze
lowers the proportion of additive. This will lower the
ability of the coolant to protect the system from pitting,
from ca
vitation, from erosion, and from deposits.
NOTICE
Do not use a conv
entional coolant to top-off a cooling
system that is filled with Extended Life Coolant (ELC).
Do not use stand
ard supplemental coolant additive
(SCA). Only use ELC Extender in cooling systems that
are filled with ELC.
Perkins ELC Ex
tender
ELC Extender is added to the cooling system halfway
through the EL
C service life. Treat the cooling system
with ELC Extender at 6000 hours or three years. Use
Table 20 in order to determine the correct amount of
ELC Extender
that is required.
Containers of several sizes are available. Consult
your Perkins
dealer or your Perkins distributor for the
part numbers.
Use the formu
la in Table 20 to determine the correct
amount of ELC Extender for your cooling system.
Refer to Operation and Maintenance Manual, “Refill
Capacities
” in order to determine the capacity of the
cooling system.

Formula For Adding ELC Extender To ELC
V×0.02=X
V is the total capacity of the cooling system.
X is the amount of ELC Extender that is required.
Table 21 is an example for using the formula that is
in Table 20.
