|---|
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. |
Obtain the sample of the coolant as close as possible to the recommended sampling interval. A consistent trend of data must be established in order to realize the full benefit of the S·O·S Services Coolant Analysis. 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.
Check the concentration of Cat SCA with a 298-5311 Coolant Nitrite Test Kit or a 294-7420 Test Kit . See this Operation and Maintenance Manual, "Cooling System Supplemental Cooling Additives (SCA) - Test/Add" for more information about testing the SCA.
Use the following guidelines for proper sampling of the coolant:
- Never collect samples from expansion bottles.
- Never collect samples from the drain for a system.
- Keep the unused sampling bottles stored in plastic bags.
- Keep the lids on empty sampling bottles until you are ready to collect the sample.
- Complete the information on the label for the sampling bottle before you begin to take the samples.
- Obtain coolant samples directly from the coolant sample port. You should not obtain the samples from any other location.
- In order to avoid contamination, immediately place the sample in the tube that is provided for mailing.
Note: Level 1 results may indicate a need for Level 2 Analysis.
For additional information about coolant analysis, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" or consult your Caterpillar dealer.
