SEAL-O-RING 2471074 - Caterpillar

Cat Extended Life Inhibitor (ELI) is water-based coolant that does not contain glycol. Cat ELI is for applications that do not require freeze protection. Exceptions are listed here. Failure to follow these recommendations can or will result in failures.Cat ELI is a corrosion inhibitor concentrate that is mixed to approximately 7.5 % by volume with water. Cat ELI has the following characteristics:
Based on the same organic additive technology that is used in Cat Extended Life Coolant (ELC)
Does not contain glycol. Designed for use in applications that do not require freeze protection.
Provides superior corrosion and cavitation protection compared to SCA mixed with water.
Provides an extended drain interval of up to 6 years or 12,000 hours. The drain interval may be longer as determined by using Cat S O S coolant analysis.
Requires little maintenance compared to conventional SCA mixed with water.Cat ELI can replace SCA/Water coolant in engine applications that do not require freeze protection.Exceptions for use of water-based ELI or SCA coolants are listed in this Special Publication, "Coolant Recommendations - Special Requirements Table".Additional information is available from your Cat Dealer. Refer to , PELJ1212, "Cat ELI – PERFORMANCE LIKE Cat ELC FOR APPLICATIONS NOT REQUIRING FREEZE PROTECTION". Refer to Table 1 for information about Cat ELI.

The recommended water for mixing with Cat ELI concentrate is distilled or deionized water. Water must meet requirements of ASTM 1193, "Type IV Reagent Water Specification". If distilled or deionized water is not available, water should meet the “Caterpillar Minimum Acceptable Water Requirements” provided in this Special Publication.To ensure a proper concentration, the preferred method is to mix Cat ELI concentrate with water. Then, add the mixed coolant to the engine cooling system. Add the proper amounts of water and Cat ELI into a clean container and mix thoroughly by manual stirring or mechanical agitation.If the preferred method cannot be performed, a Cat ELI mixture can be made by adding Cat ELI concentrate directly into engine cooling system. Add good quality water until the dilution level is approximately 7.5%. Adequate mixing is attained by operating the engine for at least 30 minutes.Appropriate mixing rates for available ELI container sizes are provided in Table 1.After the addition of water and proper mixing, the concentration of Cat ELI can be determined using the 360-0744 digital Brix refractometer.Changing to Cat ELI
For cooling systems previously running Cat ELC or an extended life coolant that meets Cat EC-1 requirements, drain the cooling system and flush with water. Then refill the cooling system with a mixture of 7.5% Cat ELI in water that meets the “Caterpillar Minimum Acceptable Water Requirements”.For cooling systems previously running a conventional
