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. |
- Observe the sight gauge in order to maintain the coolant level within the sight gauge.
- If additional coolant is necessary, remove the cooling system pressure cap that is located inside access door (1).
Note: The pressure must be removed from the system before service can be performed. Refer to this Operation and Maintenance Manual, "System Pressure Release".
- Add the appropriate amount of Extended Life Coolant and install the filler cap. Refer to the following topics:
- Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations"
