ENGINE
FUEL OIL
Cummins Diesel Engines have been developed to take
advantage of the high energy content and generally
lower cost of No.

Experience has shown
that a Cummins Diesel Engine will also operate
satisfactorily on No.

Distillation
The distillation curve should
(ASTM D-86

be smooth and
continuous.
At least 90% of the fuel
should evaporate at less than
675 deg F.
All of the fuel
should evaporate at less than
725 deg F.
Coolant
Water should be clean and free of any corrosive
chemicals such as chloride, sulphates and acids.
It
should be kept
slightly alkaline with pH value in range of 8.0 to 9.5.
Any
water which is suitable for drinking can be treated as
described in the following paragraphs for use in an
engine.
Maintain the Fleet guard DCA Water Filter on the engine.
The filter by-passes a small amount of coolant from the
system via a filtering and treating element which must be
replaced periodically.
1. In summer, with no antifreeze, fill’ system with
water.
2. In winter, select an antifreeze, all except Dow
there
209 are compatible with DCA, use with water as
required by
temperature.
Note:
Some antifreezes also contain anti-leak additives
such as inert inorganic fibers, polymer particles or ginger
root, these antifreezes should not be used in conjunction
with the water filter.
The filter element will filter out the
additives and/or become clogged and ineffective.
3. Install or replace DCA Water Filter element as
follows and as recommended in Cummins Engine
Operation and Maintenance Manuals.
Engines Equipped With
DCA Water Filters
1. New engines shipped from the Factory are
equipped with water filters containing a "DCA pre-
charge" element.
See Table 18-4.
This element is
compatible with plain water or all permanent-type
antifreezes except Dowtherm 209.

2. At the first "B" Check (oil change period) the
DCA Precharge element should be changed to DCA
Service Element.
See Table 184.
3. Replace the DCA Service Element at each
succeeding "B" Check except under the following
conditions:
a. If makeup coolant must be added between
element changes, use coolant from a pretreated supply,
as stated In "MakeUp Coolant Specifications", in Group 2
of Operation and Maintenance Manual.
b. Each time system is drained revert back to
precharge element.
