5. Flush the system with water. Flush the system
until the draining water is clear.
10. If the gasket is damaged, replace the filler cap.
Install the filler cap.
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.
11. Stop the engine.
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. Refer to the
Topic “Extended Life Coolant (ELC)” in this manual.
