Information:
ELC cooling systems can withstand contamination of up to ten percent of conventional HD coolant/antifreeze. If the contamination exceeds ten percent of the total system capacity, perform either one of the following two procedures:* Drain the cooling system. Flush the system with clean water. Refill the system with ELC.* Maintain the cooling system as if the system is filled with conventional HD coolant/antifreeze.Commercial Extended Life Coolant
If Caterpillar extended life coolant is not used, select a commercial extended life coolant that meets the Caterpillar EC-1 specification. Do not use a product that is labeled as an extended life coolant but does not meet the Caterpillar EC-1 specification. Follow the coolant maintenance guidelines of the commercial extended life coolant supplier. In all cases, use distilled or deionized water or use water that has the properties listed in the Caterpillar Water Quality Limits chart.Caterpillar Diesel Engine Antifreeze/Coolant (DEAC)
For cooling systems using conventional HD coolant, Caterpillar recommends the use of Caterpillar Diesel Engine Antifreeze/Coolant (DEAC). DEAC is an alkaline type, single-phase, ethylene glycol-based antifreeze/coolant. DEAC contains inorganic corrosion inhibitors and anti-foaming agents.Contact your Caterpillar dealer for part numbers and available container sizes.Caterpillar DEAC is available premixed with distilled water in a 50/50 concentration. If DEAC concentrate is used, Caterpillar recommends mixing the concentrate with distilled or deionized water. If distilled or deionized water is not available, use water that has the properties listed in the Caterpillar Water Quality Limits chart.Caterpillar Supplemental Coolant Additive (SCA)
Caterpillar Supplemental Coolant Additive (SCA) is effective in preventing corrosion on all metals. Caterpillar SCA also prevents the formation of mineral deposits, prevents liner cavitation, and eliminates coolant foaming.Caterpillar DEAC is formulated with the correct level of Caterpillar SCA. Additional SCA is NOT needed when the cooling system is initially filled with DEAC.Contact your Caterpillar dealer for part numbers and available container sizes.Commercial Heavy Duty (HD) Coolant/Antifreeze and SCA
If Caterpillar DEAC is not used, select a low silicate commercial HD coolant/antifreeze that meets ASTM D5345 or D4985 specifications.When a commercial HD coolant/antifreeze is used, the cooling system should be treated with three to six percent Caterpillar SCA by volume. Refer to the Caterpillar SCA Requirements for Heavy Duty Coolant/Antifreeze chart. If Caterpillar SCA is not used, select a commercial SCA. The commercial SCA must provide a minimum of 1200 mg/L or 1200 ppm (70 grains/US gal) nitrites in the final coolant mixture. Follow the coolant maintenance guidelines of the commercial SCA supplier.HD coolant/antifreezes that meet ASTM D5345 or D4985 specifications DO require SCA treatment at initial fill, and on a maintenance basis.When mixing concentrated coolants, use distilled or deionized water or use water that has the properties listed in the Caterpillar Water Quality Limits chart.Heavy Duty Coolant/Antifreeze Cooling System Maintenance
Never operate an engine without thermostats in the cooling system. Thermostats maintain the engine coolant at the proper operating temperature. Cooling system problems can develop without thermostats.
Check the coolant/antifreeze solution (glycol content) frequently to ensure adequate anti-boil and anti-freeze protection. Caterpillar recommends the use of a refractometer for checking the
