Cooling System Coolant
Sample (Level 2) - Obtain
SMCS Code: 1395-008; 1395-554
At operating temperature, engine coolant is hot
and under pressure. Hot coolant and hot components can cause severe burns. Do not allow hot
coolant or hot components to contact the skin.
Note: In order to access the sampling valve, it may
be necessary to use a portable access system
(ladder, stair assembly, man lift, or other portable
access system) that is suitable and compliant to local
regulations.

2. Obtain a coolant sample through sampling valve
(1). Take the oil sample when the engine is cool
and when the engine is operating at low idle.
3. Submit the sample for Level 1 S·O·S analysis.
Refer to the following publications for S·O·S
information:
• Operation and Maintenance Manual, “S·O·S
Information”
Obtain S·O·S samples as close as possible to the
recommended sampling interval. In order to receive
the full effect of S·O·S analysis, you must establish
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.
1. Prepare the machine for maintenance. Refer to
Operation and Maintenance Manual, “Prepare the
Machine for Maintenance”.
