RUBBER 3727811 - 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.
Do not change the coolant until you read and understand the cooling system information in Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations".Failure to do so could result in damage to the cooling system components.
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 specification for premixed or concentrate coolants. Use only Caterpillar Extender with Caterpillar ELC. Failure to follow these recommendations could result in the damage to cooling systems components.
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.
If the coolant is dirty or if you observe any foaming in the cooling system, change the coolant before the recommended interval.
Park the machine on a level surface. Ensure that the parking brake is fully engaged and shut off the engine. Do not perform this procedure until the coolant has fully cooled.

Illustration 4 g02384897
Add Extended Life Coolant until the coolant level is halfway between the top and the bottom of sight glass (5) for the coolant tank. Refer to Operation and Maintenance Manual, "Capacities (Refill)" for the required amount of Extended Life Coolant.
Start the engine. Run the engine until the water temperature regulator opens and the coolant level stabilizes. Note: Do not install the cap.
Add Extended Life Coolant in order to maintain the coolant level halfway between the top and the bottom of the sight glass.
Inspect the cap. If the cap is damaged, replace the cap.
Install the cap.
Start the engine and allow the coolant to warm. Inspect for coolant leaks. Stop the engine and make any necessary repairs.
