Repeat Steps 8 and 9 until the system is completely clean.
Fill the cooling system with the Cat ELC.
Operate the engine until the engine is warmed. While the engine is running, inspect the engine for leaks. Tighten hose clamps and connections in order to stop any leaks.
Attach the Special Publication, PMEP5027, "Label" to the cooling system filler for the engine in order to indicate the use of Cat ELC.Note: Clean water is the only flushing agent that is required when Cat ELC is drained from the cooling system.
A Level II coolant analysis by S O S Services is recommended after changing over to Cat ELC in order to ensure proper additive levels are present and in order to ensure there are no excessive levels of physical and chemical contaminantsCat ELC Cooling System Contamination
Mixing other products with Cat ELC reduces the effectiveness of the Cat ELC and shortens the Cat ELC service life. Use only Cat ELC Extender with Cat ELC. Failure to follow these recommendations can result in shortened cooling system component life.
Cat ELC cooling systems can withstand contamination to a maximum of ten percent of conventional heavy-duty coolant/antifreeze and/or SCA before the advantages of Cat ELC are reduced. If the contamination exceeds ten percent of the total system capacity; perform ONE of the following procedures:
If the cooling system contamination is caused by cooling system damage, follow the procedures under the "Changing to Cat ELC" heading. Also follow the procedures under the "Changing to Cat ELC" heading if the engine has been operated since being contaminated with more than ten percent conventional heavy-duty coolant/antifreeze and/or SCA. Certain types of cooling system contamination may require disassembly of the cooling system and manual cleaning of system components.
If the cooling system is contaminated with more than ten percent conventional heavy-duty coolant/antifreeze and/or SCA, but the engine has not been operated, drain the cooling system into a suitable container. Dispose of the coolant according to local regulations. Thoroughly flush the system with clean water. Fill the system with the Cat ELC.
Maintain the system as a conventional DEAC (Diesel Engine Antifreeze/Coolant) or other conventional coolant. If the SCA concentration is less than three percent, treat the system with an SCA. Maintain a three to six percent SCA concentration in the coolant. Change the coolant at the interval that is recommended for Cat DEAC or at the interval that is recommended for the conventional commercial coolants.
Do Not Mix Brands and/or Types of Products.Mixing other products with Cat ELC reduces the effectiveness of the Cat ELC and shortens the Cat ELC service life. Use only Cat products or commercial products that have passed the Caterpillar EC-1 specification for premixed or concentrate coolants, and that have also passed the additional requirements for EC-1 as found in the coolant section of this Special Publication. Use only Cat ELC Extender with Cat ELC. Do NOT mix brands or types of coolants. Do NOT mix brands or types of SCA. Do NOT mix brands or types of extenders. Do NOT
