BODY,SCAVENGER PUMP 8S0487 - Caterpillar

Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.
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, PERJ1017, "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.
Topping off or mixing Cat ELC with other products that do not meet Caterpillar EC-1 specifications reduces the effectiveness of the coolant, shortens coolant service life, and may cause premature wear to components.Use only Caterpillar products or commercial products that have passed the Caterpillar EC-1 specification for pre-mixed or concentrate coolants. Use only Extender with Cat ELC.Failure to follow these recommendations can result in shortened cooling system component life.
Reference: For information about the addition of Extender to your cooling system, see Operation and Maintenance Manual, "Cooling System Coolant Extender (ELC) - Add" or consult your Caterpillar dealer.If an Extended Life Coolant was previously used, flush the cooling system with clean water. No other cleaning agents are required. Use the following procedure to change the Extended Life Coolant.The cooling system pressure cap is located under the hood at the rear of the machine.

Open the coolant drain valve. The valve is located on transmission cooler and accessed from the left side of the machine. Allow the coolant to drain into a suitable container. Note: Depending on the guarding package installed, accessing the drain valve may require removal of an access plate.
Flush the cooling system with clean water until the draining water is clean. Close the drain valve.
Add the Extended Life Coolant. Reference: Refer to Operation and Maintenance Manual, "Capacities (Refill)" for the refill capacity of the cooling system.
Start the engine. Run the engine without the cooling system pressure cap until the water temperature regulator opens and the coolant level stabilizes.
Maintain the coolant level between the "MAX" and "MIN" lines on the coolant tank.
Stop the engine. Reinstall the cooling system pressure cap.
