CAMSHAFT AS 1857912 - 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.
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 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.
Refer to Special Publication, SEBU6250, "Cooling System Specification" for the cooling system requirements.Use 8T-5296 Test Kit in order to check the concentration.

(1) Filler cap for the aftercooler cooling system
(2) Filler cap for the jacket water cooling system
(3) Level gauges
Loosen filler caps (1) and (2) slowly in order to relieve pressure. Remove the filler caps.
Check level gauges (3). 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.
Refer to the table in Special Publication, SEBU6250, "Extended Life Coolant (ELC)". This table lists the correct amount of Caterpillar Extended Life Coolant (ELC) extender that should be added to the cooling system.
Clean the filler caps and inspect the filler caps. Install the filler caps.
Start the engine and check for leaks. Allow the coolant level to stabilize.
If necessary,
