KIT-SEAL 2343377 - Caterpillar

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.
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 contaminate the samples that are being drawn. This contaminate may cause a false analysis and an incorrect interpretation that could lead to concerns by both dealers and customers.
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.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, a consistent trend of data must be established. 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.Note: Level 1 results may indicate a need for Level 2 Analysis.
Prepare the machine for maintenance. Refer to Operation and Maintenance Manual, "Prepare the Machine for Maintenance".
