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, "Maintenance Section".

    Typical example

  2. Remove the coolant temperature switch (1) from the water temperature regulator housing (2).

  3. Inspect the coolant temperature switch (1) for damage. If the coolant temperature switch is damaged, use a new part for replacement. For information on testing the coolant temperature switch for correct operation, refer to Testing and Adjusting, "Coolant Temperature Switch - Test".
