CABLE AS- 2183997 - 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, 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.
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.
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.

DrainSome parts are not shown for clarity.
Open the drain valve on the bottom radiator tube. The drain is on the top of the front of the fuel tank. The drain valve can be accessed from the left side of the machine. Allow the coolant to drain into a suitable container.
Flush the cooling system with clean water until the draining water is clean. Close the drain valve.
Replace the water temperature regulator.ReferenceRefer to Operation and Maintenance Manual, "Cooling System Water Temperature Regulator - Replace" for the correct procedure.
Add the Extended Life Coolant.ReferenceRefer 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.
Install the cooling system pressure cap. Stop the engine.
