Removal Procedure (C0.5 and C0.7 engines)


NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.



NOTICE

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.


  1. Drain the coolant from the cooling system into a suitable container for storage or disposal. Refer to Operation and Maintenance Manual, "Refill Capacities" for the approximate capacity of the cooling system.

    Typical example

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

    Personal injury can result from parts and/or covers under spring pressure.

    Spring force will be released when covers are removed.

    Be prepared to hold spring loaded covers as the bolts are loosened.


  2. Remove the setscrews (6) and the nuts (5).

  3. Remove the outlet connection (4) for the water temperature regulator.

  4. Remove the joint (3).

  5. Remove the water temperature regulator (2) and the spring (1) from the cylinder head.

  6. Inspect the water temperature regulator (2) for wear or damage. If the water temperature regulator is worn or damaged, use a new part for replacement. Refer to Testing and Adjusting, "Water Temperature Regulator - Test" for more information on testing the water temperature regulator.
