CYLINDER GP-BOOM 1948407 - Caterpillar

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 cooling system pressure cap slowly to relieve pressure only when engine is stopped and cooling system pressure 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 Coolant Additive contains alkali. Avoid contact with skin and eyes.
Use Caterpillar Extended Life Coolant (ELC) when you add coolant to the cooling system. See Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations" for all cooling system requirements.Use a Coolant Conditioner Test Kit in order to check the concentration of the coolant.
Mixing ELC with other products will reduce the effectiveness of the coolant.This could result in damage to cooling system components.If Caterpillar products are not available and commercial products must be used, make sure they have passed the Caterpillar EC-1 specification for pre-mixed or concentrate coolants and Caterpillar Extender.
Note: This machine was filled at the factory with Caterpillar Extended Life Coolant.
Park the machine on level ground.
Stop the engine.
Unlatch the engine hood and raise the engine hood.

Make sure that the cooling system has cooled down. Loosen the cooling system pressure cap slowly in order to relieve system pressure. Remove the pressure cap. Note: Refer to Operation and Maintenance Manual, "General Hazard Information" for information on containing fluid spillage.
It may be necessary to drain some coolant from the radiator so that Caterpillar Extender can be added to the cooling system. Note: Always discard drained fluids according to local regulations.
Add Caterpillar Extended Life Coolant (ELC) to the cooling system. Refer to the following topics for the proper amount of Caterpillar Extender:
Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations"
