CONTROL & MTG GP-ELECTRONIC 3979348 - 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.
Obtain the sample of the coolant from surge tank as close as possible to the recommended sampling interval. In order to receive the full effect of S O S analysis, establishing a consistent trend of data is necessary. 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.Level 2 Analysis

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
Testing the coolant can be done at your Cat dealer. Caterpillar S O S Coolant Analysis is the best way to monitor the condition of your coolant and your cooling system. S O S Coolant Analysis is a program that is based on periodic samples.Perform a Coolant Analysis (Level 2) at initial 500 hours for systems that contain extended life coolant (ELC). Perform the analysis yearly after the initial 500 hours.
Park the machine on a hard, level surface. Set the engine at low idle speed.

Open the left engine compartment door (not shown). Unlock top access door (1) that is inside the engine compartment. Remove filler cap (2) to take the coolant sample.
Use the following 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.
Keep the lids on empty sampling bottles until you are ready to collect the sample.
Place the sample in the mailing tube immediately after obtaining the sample in order to avoid contamination.
Never collect samples from the drain for a system.
Replace filler cap (2). Lock top access door (1) that is inside the engine compartment.
Close the left engine access door.
Submit the sample for Level 1 analysis. For additional information about coolant analysis, see Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations" or consult your Cat dealer.
