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.

When a Caterpillar Extended Life Coolant (ELC) is used, an Extender must be added to the cooling system. See the Special Publication, SEBU6250, "Coolant Recommendations" for all cooling system requirements.Use a coolant conditioner test kit in order to check the concentration of the coolant.
Use only Caterpillar products or commercial products that have passed Caterpillar EC-1 specification for pre-mixed or concentrated coolants.Use only Caterpillar Extender with Extended Life Coolant.Mixing Extended Life Coolant with other products reduces the Extended Life Coolant service life. Failure to follow the recommendations can reduce cooling system components life unless appropriate corrective action is performed.
