Adding the SCA to Heavy-Duty Coolant
at the Initial Fill
Use the equation that is in Table 18 to determine the
amount of SCA that is required when the cooling
system is initially filled.
Table 18
Equation For Adding The SCA To The Heavy-Duty Coolant At
The Initial Fill
V × 0.045 = X
V is the total volume of the cooling system.
X is the amount of SCA that is required.
Table 19 is an example for using the equation that is
in Table 18 .

Adding The SCA to The Heavy-Duty
Coolant For Maintenance
Heavy-duty antifreeze of all types REQUIRE periodic
additions of an SCA.
Test the antifreeze periodically for the concentration
of SCA. For the interval, refer to the Operation and
Maintenance Manual, “Maintenance Interval
Schedule” (Maintenance Section). Cooling System
Supplemental Coolant Additive (SCA) Test/Add.
Additions of SCA are based on the results of the test.
The size of the cooling system determines the
amount of SCA that is needed.
Use the equation that is in Table 20 to determine the
amount of SCA that is required, if necessary:
Table 20
Equation For Adding The SCA To The Heavy-Duty Coolant
For Maintenance
V × 0.014 = X
V is the total volume of the cooling system.
X is the amount of SCA that is required.
Table 21 is an example for using the equation that is
in Table 20 .

Cleaning the System of Heavy-Duty
Antifreeze
• Clean the cooling system after used coolant is
drained or before the cooling system is filled with
new coolant.
• Clean the cooling system whenever the coolant is
contaminated or whenever the coolant is foaming.

Recommendations
(Diesel

Fluid
(DEF))
General
Information
Diesel
Exhaust
Fluid
(DEF)
is
a
liquid
that
is
injected
into
the
aftertreatment
system
before
Selective
Catalytic
Reduction
(SCR).
This
system
of
injecting
the
DEF
into
the
exhaust
will
cause
a
chemical
reaction
in
the
SCR
system.
The
Nitrogen
Oxide
(NOx)
molecules
in
the
exhaust
are
converted
to
elemental
nitrogen
and
water.
This
conversion
will
reduce
the
emission
of
the
engine.
Specification
DEF
that
is
used
in
Perkins
engines
must
meet
the
ISO
specification
22241-1
for
quality.
The
ISO
specification
22241-1
requirements
are
met
by
many
brands
of
DEF,
including
the
ones
that
carry
the
AdBlue
or
API
certification."
The
document
series
ISO
standard
22241
will
give
information
on
quality
requirements,
test
methods,
handling,
transportation,
storage,
and
refilling
interface.
Spillage
Care
should
be
taken
when
dispensing
DEF.
Spills
should
be
cleaned
immediately.
All
surfaces
should
be
wiped
clean
and
rinsed
with
water.
DEF
that
has
been
spilt
will
crystallize
when
the
water
within
the
liquid
evaporates.
Spilt
DEF
will
attack
paint
and
metal.
If
DEF
is
spilt,
wash
the
area
with
water.
