Note:
A commercial heavy-duty antifreeze that
meets “ASTM D4985” specifications MAY require a
treatment with an SCA at the initial fill. Read the label
or the instructions that are provided by the OEM of
the product.
In stationary engine applications and marine engine
applications that do not require anti-boil protection or
freeze protection, a mixture of SCA and water is
acceptable. Perkins recommends a six percent to
eight percent concentration of SCA in those cooling
systems. Distilled water or deionized water is
preferred. Water which has the recommended
properties may be used.

ELC
Perkins provides ELC for use in the following
applications:
• Heavy-duty spark ignited gas engines
• Heavy-duty diesel engines
• Automotive applications
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 formulated with the correct amount of these
additives in order to provide superior corrosion
protection for all metals in engine cooling systems.
ELC is available in a premixed cooling solution with
distilled water. ELC is a 1:1 mixture. The Premixed
ELC provides freeze protection to −36 °C (−33 °F).
The Premixed ELC is recommended for the initial fill
of the cooling system. The Premixed ELC is also
recommended for topping off the cooling system.
Containers of several sizes are available. Consult
your Perkins distributor for the part numbers.
ELC Cooling System Maintenance
Correct additions to the Extended Life
Coolant
NOTICE
Use only Perkins products for pre-mixed or concen-
trated coolants.
Mixing Extended Life Coolant with other products re-
duces the Extended Life Coolant service life. Failure
to follow the recommendations can reduce cooling
system components life unless appropriate corrective
action is performed.
In order to maintain the correct balance between the
antifreeze and the additives, you must maintain the
recommended concentration of 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 cavitation, from
erosion, and from deposits.
NOTICE
Do not use a conventional coolant to top-off a cooling
system that is filled with Extended Life Coolant
(ELC).
Do not use standard supplemental coolant additive
(SCA).
When using Perkins 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
specified coolant change interval. Cleaning agents
are only required if the system has been
contaminated by the addition of some other type of
coolant or by cooling system damage.
Clean water is the only cleaning agent that is
required when ELC is drained from the cooling
system.
Before the cooling system is filled, the heater control
(if equipped) 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 refilled, operate the engine until the coolant level
reaches the normal operating temperature and until
the coolant level stabilizes. As needed, add the
coolant mixture in order to fill the system to the
specified level.
