Obtain Coolant Analysis
The concentration of supplemental coolant additive
(SCA) should be checked regularly with test kits or
with S·O·S Coolant Analysis (Level I).
A coolant analysis can be conducted in order to verify
the condition of the water that is being used in the
cooling system. A full water analysis can be obtained
by consulting your local water utility company or an
agricultural agent. Private laboratories are also
available for water analysis.
Caterpillar Inc. recommends an S·O·S Coolant
Analysis (Level II).
S·O·S Coolant Analysis (Level II)
An S·O·S Coolant Analysis (Level II) is a
comprehensive coolant analysis which completely
analyzes the coolant and the effects on the cooling
system. An S·O·S Coolant Analysis (Level II)
provides the following information:
• Complete S·O·S Coolant Analysis (Level I)
• Visual inspection of properties
• Identification of metal corrosion
• Identification of contaminants
• Identification of built up impurities (corrosion and
scale)
S·O·S Coolant Analysis (Level II) provides a report of
the results of both the analysis and the maintenance
recommendations.
For more information about coolant analysis, see
your Caterpillar dealer.

Radiator - Clean
SMCS Code: 1353-070
Note: Adjust the frequency of cleaning according to
the effects of the operating environment.
Inspect the radiator for these items: damaged fins,
corrosion, dirt, grease, insects, leaves, oil and other
debris. Clean the radiator, if necessary.
Personal injury can result from air pressure.
Personal injury can result without following prop-
er procedure. When using pressure air, wear a
protective face shield and protective clothing.
The maximum air pressure for cleaning purposes
must be reduced to 205 kPa (30 psi) when the air
nozzle is deadheaded.
Pressurized air is the preferred method for removing
loose debris. Direct the air in the opposite direction of
the air flow. Hold the nozzle approximately 6 mm
(0.25 inch) away from the fins. Slowly move the air
nozzle in a direction that is parallel with the tubes.
This movement will remove debris that is between
the tubes.
Pressurized water may also be used for cleaning.
The maximum water pressure for cleaning purposes
must be less than 275 kPa (40 psi). Use pressurized
water in order to soften mud. Clean the core from
both sides.
Use a degreaser and steam for removal of oil and
grease. Clean both sides of the core. Wash the core
with detergent and hot water. Thoroughly rinse the
core with clean water.
After cleaning, start the engine and accelerate the
engine to high idle rpm. This procedure will help in
the removal of debris and drying of the core. Stop the
engine. Use a light bulb behind the core in order to
inspect the core for cleanliness. Repeat the cleaning,
if necessary.
Inspect the fins for damage. Bent fins may be opened
with a “comb”. Inspect these items for good condition:
welds, mounting brackets, air lines, connections,
clamps and seals. Make repairs, if necessary.
