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 Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Note: Install caps and plugs on all openings in order to prevent dirt or debris from entering the system. Cleanliness is an important factor. Before the removal procedure, the exterior of the component should be thoroughly cleaned. This will prevent dirt from entering the internal mechanism.
Position a suitable container below the radiator in order to contain the coolant for storage or for disposal. Drain the coolant from the radiator. Refer to Operation and Maintenance Manual, "Cooling System Coolant (ELC) - Change". The capacity of the radiator is 268 L (71 US gal).
