Use only Cat products or commercial products that have passed the Caterpillar EC-1 specification for pre-mixed or concentrated coolants.Use only Cat ELC Extender with Cat ELC.Do NOT use conventional SCA with Cat ELC. Mixing Cat ELC with conventional coolants and/or conventional SCA reduces the Cat ELC service life.Do NOT mix brands or types of coolant. Do NOT mix brands or types of SCA and/or brands or types of extenders. Different brands or types may use different additive packages to meet the cooling system requirements. Different brands or types may not be compatible.Do not mix brands or types of coolants with different brands or types of SCA or extender. Cat Extender is compatible with Cat ELC. If using non Cat EC-1 coolant, refer to the coolant manufacturer for information on a compatible extender.Failure to follow the recommendations can reduce cooling system component life unless appropriate corrective action is performed.
In order to maintain the correct balance between the antifreeze and the additives, you must maintain the recommended concentration of ELC. Lowering the proportion of antifreeze lowers the proportion of additive. This will lower the ability of the coolant to protect the system from pitting, from cavitation, from erosion, and from deposits.During daily maintenance, use the premixed Cat ELC as a cooling system top-off. This will bring the coolant up to the proper level. Check the specific gravity of the coolant system with the 245-5829 Coolant/Battery Tester/Refractometer . This tester gives readings that are immediate and accurate in both degrees Celsius and degrees Fahrenheit. Use Cat ELC Concentrate to restore the proper glycol concentration in the coolant system. This should be done before the engine is exposed to freezing temperatures.
Do not use a conventional coolant to top-off a cooling system that is filled with Cat ELC.Do not use conventional SCA. Only use Cat ELC Extender in cooling systems that are filled with Cat ELC.
Do not top-off the cooling system with water unless there is a specific need to adjust the water/glycol ratio. Compatible 50/50 (water/glycol) coolant is typically used and recommended when cooling system top-off is required.Cat ELC Extender
Cat ELC Extender is added to the cooling system halfway through the ELC service life. Treat the cooling system with ELC Extender at 483 000 km (300,000 miles) or 3 years. Use Table 1 in order to determine the proper amount of ELC Extender that is required.Containers of several sizes are available. Consult your Caterpillar dealer for the part numbers.

When using Cat ELC, do not use conventional SCAs, or, if equipped, SCA maintenance elements. In order to avoid SCA contamination of a Cat ELC system, remove the SCA element base and plug off or bypass the coolant lines.
Cat ELC Cooling System Cleaning
Note: If the cooling system is already using Cat ELC, cleaning agents are not required to be used at the specified coolant change interval. Cleaning agents are only required if the system has been contaminated by the addition of some other type of coolant or by cooling system damage.Clean water is the only cleaning agent that is required when Cat ELC is drained from the cooling system.After the cooling system is drained and after the cooling system is refilled, operate the engine while the cooling system filler cap is removed. Operate the engine until the coolant level reaches the normal operating temperature and until the coolant level stabilizes. As needed, add the coolant mixture in order to fill the system to the proper level.A Level II coolant analysis by S O S Services is recommended after cooling system cleaning and refill in order to ensure proper additive levels are present and in order to ensure there are no excessive levels of physical contaminants and chemical contaminants.Recycling Cat ELC
Cat ELC can be recycled into conventional coolants. The drained coolant mixture can be distilled in order to remove the ethylene glycol and the water. The ethylene glycol and the water can be reused. The distilled material does not contain the additives that are required to be classified as either Cat ELC or Cat DEAC. Consult your Caterpillar dealer for more information. Recycled coolants should meet "ASTM D6210-06"Changing to Cat ELC
To change from heavy-duty coolant/antifreeze to the Cat ELC, perform the following steps:
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, "Caterpillar Dealer Service Tool Catalog" and to Special Publication, PECJ0003, "Cat Shop Supplies and Tools" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to applicable regulations and mandates.
Drain the coolant into a suitable container.
Dispose of the coolant according to local regulations.
If equipped, remove the empty SCA maintenance element and remove the element base. Plug the coolant lines or bypass the coolant lines.
Do not leave an empty SCA maintenance element on a system that is filled with Cat ELC.The element housing may corrode and leak causing an engine failure.Remove the SCA element base and plug off or by-pass the coolant lines.
Flush the
