BELLOWS AS 2342880 - Caterpillar

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 the Caterpillar EC-1 specification. Before the engine is exposed to freezing temperatures, check the freeze protection (glycol concentration) of the coolant with the 1U-7298 Coolant/Battery Tester (Celsius) or with the 1U-7297 Coolant/Battery Tester (Fahrenheit). Use ELC Concentrate to adjust the glycol concentration, if necessary. ELC Concentrate can be used to lower the freezing point to −51 °C (−60 °F).Caterpillar ELC Extender
Caterpillar ELC Extender is added to the cooling system halfway through the ELC service life. Treat the cooling system with ELC Extender at three years or one half of the coolant service life. Refer to the specific engine's Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section).Containers of several sizes are available. Consult your Caterpillar dealer for the part numbers.Adding ELC Extender
The amount of ELC Extender that is required depends on the capacity of the cooling system. Use the equation that is in Table 1 in order to determine the proper amount of ELC Extender that is required.
Table 1
Equation For Adding ELC Extender To ELC
V × 0.02 = X
V is the total volume of the cooling system.
X is the amount of ELC Extender that is required. Table 2 is an example for using the equation that is in Table 1.

(250 US gal) × 0.02 19 L
(5 US gal) ELC 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.The ELC can be recycled. The drained coolant mixture can be distilled. The distillation process can remove the ethylene glycol and the water. Consult your Caterpillar dealer for more information.After the cooling system is drained and 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.Changing to Caterpillar ELC
To change from heavy-duty coolant/antifreeze to the Caterpillar 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, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Drain the coolant into a suitable container. Dispose of the coolant according to
