Cooling System Coolant Sample (Level 2) - Obtain
Obtain the samp
le of the coolant as close as possible
to the recommended sampling interval. In order
to receive the full effect of S·O·S analysis, you
must establis
h a consistent trend of data. In order
to establish a pertinent history of data, perform
consistent samplings that are evenly spaced.
Supplies for
collecting samples can be obtained from
your Caterpillar dealer.
Use the follo
wing guidelines for proper sampling of
the coolant:
•
Complete the
information on the label for the
sampling bottle before you begin to take the
samples.
•
Keep the unused sampling bottles stored in plastic
bags.
•
Obtain coolant samples directly from the coolant
sample port. You should not obtain the samples
from any ot
her location.
•
Keep the lids on empty sampling bottles until you
are ready t
o collect the sample.
•
Place the sample in the mailing tube immediately
after obta
ining the sample in order to avoid
contamination.
•
Never coll
ect samples from expansion bottles.
•
Never collect samples from the drain for a system.
Submit the sample for Level 1 analysis.

NOTICE
Always use a designated pump for oil sampling, and
use a separate designated pump for coolant sampling.
Using the same pump for both types of samples may
contam inate the samples that are being drawn. This
contaminate may cause a false analysis and an incor-
rect interpretation that could lead to concerns by both
dealers and customers.
Refer to Operation and Maintenance Manual,
“Cooling System Coolant Sample (Level 1) - Obtain”
for the guidelines for proper sampling of the coolant.
Submit the samp
le for Level 2 analysis.
For additional information about coolant analysis,
refer to the Op
eration and Maintenance Manual,
“Refill Capacities and Recommendations” topic or
consult your Caterpillar dealer.

SMCS Code: 1352-045; 1395-081
This maintenance procedure is required for
conventional coolants such as DEAC and for
mixtures of water and SCA. This maintenance is
NOT required for cooli ng systems that are filled
with Extended Life Coolant.
Cooling system coolant additive contains a lkali.
To help prevent personal injury, avoid contact with
the sk in and eyes. Do not drink cooling system
coolant additive.
Note: Caterpillar recommends an S·O·S coolant
analysis (Level 1).
Test the Concentration of the SCA
Coolant/Antifreeze and SCA
NOTICE
Do not exceed the recommended six percent supple-
mental coo
lant additive concentration.
Test the concentration of the SCA with the 8T-5296
Coolant Conditioner Test Kit.
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. Use the instructions
that foll
ow:
1. Fillthesyringetothe“1.0ml”markwiththe
coolant.
2. Dispense the 1.0 mL coolant sample from the
