Caterpillar D3K, D4K and D5K: Maintenance (Initial 500 Service Hours)

This procedure that is done for the 1st initial 500 Service Hours focuses on your equpment's cooling system coolant sample. It also provides the complete list of guidelines for proper sampling of the coolant.

    Cooling System Coolant Sample (Level 1) - Obtain

    Note: Obtain a Coolant Sample (Level 1) if the cooling system is filled with any other coolant instead of Cat ELC.

    This includes the following types of coolants.

    NOTICE: 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 incor- rect interpretation that could lead to concerns by both dealers and customers.

    Note: Level 1 results may indicate a need for Level 2 Analysis.

    Note: Always discard drained fluids according to local regulations.

    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, 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.

    Use the following guidelines for proper sampling of the coolant:
