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 filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes.
Slowly loosen filler cap (1) in order to relieve system pressure. Remove the filler cap.

Open the drain valves. Allow the coolant to drain into a suitable container.
Flush the system with water. Flush the system until the draining water is clear. Note: If the cooling system is already using ELC, cleaning agents are not required to be used at the specified coolant change interval. Cleaning agents are only required if the system has been contaminated by the addition of some other type of coolant or by cooling system damage. Clean water is the only cleaning agent that is required when ELC is drained from the cooling system.Note: If you change to an ELC from another type of coolant, use a Caterpillar cleaning agent to flush the cooling system. After you drain the cooling system, thoroughly flush the cooling system with clean water. All of the cleaning agent must be removed from the cooling system.
Close the drain valves and install the plug.
Replace front bottom guard (3).
Add the ELC solution. See the following topics in this publication:
Capacities (Refill) Note: Caterpillar antifreeze contains additive. If you are using Caterpillar antifreeze, do not add the supplemental coolant additive at this time. Also, do not change the supplemental coolant additive element at this time.
Start the engine. Run the engine without the filler cap until the thermostat opens and the coolant level stabilizes.
