ENGINE AR-COMPLETE 3942402 - 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.
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.
Mixing Cat 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 concentrate coolants. Use only Cat Extender with Cat ELC. Failure to follow these recommendations could result in damage to the cooling systems components.If ELC cooling system contamination occurs, refer to Operation and Maintenance, "Extended Life Coolant (ELC)" under the topic ELC Cooling System Contamination.This machine was factory filled with Cat Extended Life Coolant.
Illustration 1 g01899933If coolant needs to be added daily, check for leaks.
Prepare the machine for maintenance. Refer to Operation and Maintenance Manual, "Prepare the Machine for Maintenance".
Use coolant level gauge (1) in order to check the coolant levels. The needle should be in the green range.
If the gauge indicator is in the red range, allow the engine to cool and loosen filler cap (2) slowly. Then add premixed coolant in order to bring the coolant in the green range on the coolant level gauge. Refer to Operation and Maintenance Manual, "Cooling System Coolant Extender (ELC) - Add" for more information.
