FRAME-FRONT 3005620 - Caterpillar

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.
For conventional heavy-duty coolant/antifreeze, check the concentration of supplemental coolant additive (SCA) regularly. The concentration of SCA can be checked with an S O S coolant analysis (Level 1).Obtain the sample of the coolant 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 is required. 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 Cat dealer.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.Submit the sample for Level 1 analysis.Note: Level 1 results may indicate a need for Level 2 Analysis.For additional information about coolant analysis, see the Special Publication, SEBU6400, "Cat Gas Engine Lubricant, Fuel, and Coolant Recommendations" or consult your Cat dealer.
