Removal Procedure
Start By:
Install the wheel chocks. Refer to Disassembly and Assembly, "Wheel Chocks (Front and Rear) - Remove and Install".
Personal injury can result from hot coolant, steam and alkali.At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.Remove cooling system pressure cap slowly to relieve pressure only when engine is stopped and cooling system pressure cap is cool enough to touch with your bare hand.Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns.Cooling System Coolant Additive contains alkali. Avoid contact with skin and eyes.
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.
Position a suitable container under the radiator drain valves in order to contain coolant for storage or disposal. Drain approximately 397 L (105 US gal) from the right side of the radiator. Refer to Operation and Maintenance Manual, "Cooling System Coolant (ELC) - Change" for the correct procedure.
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 components should be cleaned. This will help to prevent dirt from entering the internal mechanism.
