Removal Procedure
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, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: These engines have two water temperature regulators. The procedure that is described will work for both of the water temperature regulators. Only one water temperature regulator is described for the removal procedure. Follow the same procedure for the second water temperature regulator.
Drain the coolant from the engine to a level that is below the water temperature regulators. Use a suitable container for storage or disposal of the coolant.
