Cooling System Coolant
Sample (Level 2) - Obtain
SMCS Code: 1350-008; 1395-554; 1395-008; 7542
NOTICE
Always use a designated pump for oil sampling, and
use a separate designated pump for coolant sam-
pling. Using the same pump for both types of sam-
ples may contaminate the samples that are being
drawn. This contaminate may cause a false analysis
and an incorrect interpretation that could lead to con-
cerns by both dealers and customers.
Obtain the sample of the coolant as close as possible
to the recommended sampling interval. Supplies for
collecting samples can be obtained from your
Caterpillar dealer.
Reference: Refer to Operation and Maintenance
Manual, “Cooling System Coolant Sample (Level 1) -
Obtain” for the guidelines for proper sampling of the
coolant.
Submit the sample for Level 2 analysis.
Reference: For additional information about coolant
analysis, refer to Special Publication, SEBU6250,
“Caterpillar Machine Fluids Recommendations” or
consult your Caterpillar dealer.

Cooling System Supplemental
Coolant Additive (SCA) - Test/
Add
SMCS Code: 1352-045; 1395-081
Cooling system coolant additive contains alkali.
To help prevent personal injury, avoid contact
with the skin and the eyes. Do not drink cooling
system coolant additive.
Note: Test the concentration of the Supplemental
Coolant Additive (SCA) or test the SCA concentration
as part of an S·O·S Coolant Analysis.
Test for SCA Concentration
Coolant and SCA
NOTICE
Do not exceed the recommended six percent supple-
mental coolant additive concentration.
Use the 8T-5296 Coolant Conditioner Test Kit or
use the 4C-9301 Coolant Conditioner Test Kit in
order to check the concentration of the SCA. Refer to
this Operation and Maintenance Manual, “Refill
Capacities and Recommendations” for more
information.
Water and SCA
NOTICE
Do not exceed the recommended eight percent sup-
plemental coolant additive concentration.
Test the concentration of the SCA with the 8T-5296
Coolant Conditioner Test Kit. Refer to the Special
Publication, SEBU6251, “Caterpillar Commercial
Diesel Engine Fluids Recommendations” for more
information.
S·O·S Coolant Analysis
S·O·S coolant samples can be analyzed at your
Caterpillar dealer. S·O·S Coolant Analysis is a
program that is based on periodic samples.
Level 1
Level 1 is a basic analysis of the coolant. The
following items are tested:
• Glycol Concentration
• Concentration of SCA
• pH
• Conductivity
The results are reported, and recommendations are
made according to the results. Consult your
Caterpillar dealer for information on the benefits of
managing your equipment with an S·O·S Coolant
Analysis.
