3500 and 3500B Engines Aftercooler Core - Inspect/Clean

  1. Remove the core. Refer to the Disassembly and Assembly Manual, "Aftercooler - Remove and Install" for the procedure.

  2. Turn the aftercooler core on one side in order to remove debris. Remove the debris that is accessible.


    NOTICE

    Do not use a high concentration of caustic cleaner to clean the core. A high concentration of caustic cleaner can attack the internal metals of the core and cause leakage. Only use the recommended concentration of cleaner.


  3. Back flush the core with cleaner.

    AVSpare recommends the use of Hydrosolv liquid cleaner. Table 1 lists Hydrosolv liquid cleaners that are available from your AVSpare dealer.

    Table 1
    Hydrosolv Liquid Cleaners(1) 
    Part Number  Description  Size 
    1U-5490  Hydrosolv 4165  19 L (5 US gallon) 
    174-6854  Hydrosolv 100  19 L (5 US gallon) 
    (1) Use a two to five percent concentration of the cleaner at temperatures up to 93°C (200°F). Consult your AVSpare dealer for more information.

  4. Remove the drain plug.

  5. Steam clean the core in order to remove any residue. Flush the fins of the aftercooler core. Remove any other trapped debris from the inside and from the outside of the core.

    Note: Do not use high pressure when the fins are cleaned. High pressure can damage the fins.

  6. Wash the core with hot, soapy water.

  7. Flush the core thoroughly in order to remove residue and remaining debris. Flush the core with clean, fresh water until the water that is exiting the core is clear and free of debris.

    ------ WARNING! ------

    Personal injury can result from air pressure.

    Personal injury can result without following proper procedure. When using pressure air, wear a protective face shield and protective clothing.

    Maximum air pressure at the nozzle must be less than 205 kPa (30 psi) for cleaning purposes.


  8. Dry the core with compressed air. Direct the air in the reverse direction of the normal flow.

  9. Prior to installation, inspect any O-rings or seals for damage. If necessary, replace the O-rings or seals.

  10. Inspect the core for trapped debris and cleanliness. If it is necessary, remove the debris and repeat the cleaning procedure.

  11. Inspect the core for damage and perform a pressure test in order to detect leaks. Many shops that service radiators are equipped to perform pressure tests.

  12. Install the core. Refer to Disassembly and Assembly Manual, "Aftercooler - Remove and Install" for the procedure.

For more information on cleaning the core, consult your AVSpare dealer.
