Use only Caterpillar products or commercial products that have passed Caterpillar EC-1 specification for pre-mixed or concentrated coolants. Use only Caterpillar Extender with Extended Life Coolant. Mixing Extended Life Coolant with other products reduces the Extended Life Coolant service life. Failure to follow the recommendations can reduce cooling system components 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 Extended Life Coolant (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.
Proper additions to the Extended Life Coolant
Note: Do not add ELC Concentrate as a makeup solution for maintaining the correct coolant level. The addition of the concentrated Extended Life Coolant will increase the concentration of glycol in the cooling system.
During daily maintenance, use the premixed ELC as a cooling system top-off. This will bring the coolant up to the proper level. Use ELC or use a coolant that meets Caterpillar specifications (EC-1). Check the specific gravity of the coolant system with a 366 075.0 Coolant/Battery Tester (C°). Use 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 using Extended Life Coolant. Do not use supplemental coolant additives (SCA) other than Extender in cooling systems filled with Extended Life Coolant. |
Extended Life Coolant Cooling System Cleaning
Note: If the cooling system is already using 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 ELC is drained from the cooling system.
ELC can be recycled. The drained coolant mixture can be distilled. The distillation process can remove the ethylene glycol and the water. Consult your CLAAS dealer for more information.
After you drain the cooling system and after you refill the cooling system, operate the engine while the radiator filler cap is removed. Operate the engine until the coolant 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.
