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 s topped a nd radiator 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 Conditioner contains alkali. Avoid
contact with skin and eyes.
When Caterpillar Extended Life Coolant (ELC)
is used, an extender must be added to the
cooling system. See Operation and Maintenance
Manual, “Maintenance Interval Schedule” for the
proper service interval. The amount of extender is
determined by the cooling system capacity.
