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.
Adding coolant to an overheated engine could result in damage to the engine. Allow the engine to cool before adding coolant.If the machine is to be stored in, or shipped to, an area with freezing temperatures, the cooling system must be protected to the lowest outside (ambient) temperature.The engine cooling system is normally protected to a minimum of −29°C (−20°F) with Caterpillar Antifreeze, when shipped from the factory unless special requirements are defined.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Excessive additive (greater than the recommended 6% initial fill) together with concentrations of antifreeze greater than 60% cause deposits to form and can result in radiator tube blockage and overheating.
Mixing Extended Life Coolant (ELC) with other products reduces the effectiveness of the coolant and shortens coolant life. Use only Caterpillar products or commercial products that have passed the Caterpillar EC-1 specifications for premixed or for concentrate coolants. Use only Caterpillar Extender with Caterpillar ELC. Failure to follow these recommendations could result in the damage to cooling system components.If ELC cooling system contamination occurs, refer to Operation and Maintenance Manual, SEBU6250, "Caterpillar Machine Fluids Recommendations" under the topic of ELC Cooling System Contamination.This machine was factory filled with Extended Life Coolant.
Refer to Special Publications, SEBU6250, "Caterpillar Machine Fluids Recommendations" for the cooling system requirements.
Park the machine on a level surface and stop the engine. Make sure that the transmission control is in the PARK position.

Observe the sight gauge (3) in order to check the coolant level. If necessary, drain enough coolant in order to allow the addition of the liquid coolant additive. Note: Make sure that the coolant is drained into a suitable container.
Add Cat cooling system coolant extender to the cooling system. Refer to Special Publication, SEBU6250, "Cooling System Specifications" and Operation and Maintenance Manual, "Capacities (Refill)" for the proper amount of Cat extender.
Clean the radiator cap and inspect the radiator cap. Install the radiator cap.
Start the engine and check the
