CAGE 7B0377 - 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.
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.
Do not change the coolant until you read and understand the material in the Cooling System Specifications section.
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.
Whenever the coolant is dirty or whenever foaming is observed, change the coolant before the recommended interval.
Park the machine on a level surface and stop the engine. Make sure that the transmission control is in the PARK position.

Open drain valve (3) and drain the coolant into a suitable container.
Close the drain valve. Fill the system with clean water and a 6 to 10% concentration of cooling system cleaner.
Start the engine and operate the engine for 90 minutes. Stop the engine and drain the cleaning solution into a suitable container.
With the engine stopped, flush the system with water until the draining water is clear. Drain the water into a suitable container.
Close the drain valve.
Add the coolant solution. Refer to Special Publication, SEBU6250, "Cooling System Specifications" and Operation and Maintenance Manual, "Capacities (Refill)" for further information.
Start the engine. Run the engine without the radiator cap. Run the engine until the thermostat opens and the coolant level stabilizes. This should purge the air from the system. Check the coolant level. Refer to Operation and Maintenance Manual, "Cooling System Coolant Level - Check" for further information.
Install the radiator cap.
