Refer to "ISO 22241" document series for more information about DEF quality control.Note: Dispose of all fluids according to applicable regulations and mandates.Filling Tank
The DEF tank filler cap is colored blue. A special nozzle size is required in order to fill a DEF tank. Ensure that the DEF tank is on level ground before the tank is filled.Spillage
Care should be taken when dispensing DEF. Spills should be cleaned immediately. All surfaces should be wiped clean and rinsed with water. DEF that has been split will crystallize when the water within the liquid evaporates. Split DEF will attack paint and metal. If DEF is split, wash the area with water.Caution should be used when dispensing DEF near an engine that has recently been running. Spilling DEF onto hot components may cause the release of ammonia vapors. Do not breathe ammonia vapors. Do not clean up any spills with bleach.Coolant
The following two coolants are used in Caterpillar diesel engines:Preferred - Cat ELC (Extended Life Coolant) or a commercial extended life coolant that meets the Caterpillar EC-1 specificationAcceptable - A Cat DEAC (Diesel Engine Antifreeze/Coolant) or a commercial heavy-duty antifreeze that meets "ASTM D6210" specifications
The Caterpillar industrial engine must be operated with a 1:1 mixture of water and glycol. This concentration allows the NOx reduction system to operate correctly at high ambient temperatures.
Do not use a commercial coolant/antifreeze that only meets the ASTM "D3306" or equivalent specification. This type of coolant/antifreeze is made for light duty automotive applications.Use only the coolant/antifreeze that is recommended.
Caterpillar recommends a 1:1 mixture of water and glycol. This mixture of water and glycol will provide optimum heavy-duty performance as an antifreeze.Note: Cat DEAC does not require a treatment with an SCA at the initial fill. Commercial heavy-duty antifreeze that meets "ASTM D6210" specifications MAY require a treatment with an SCA at the initial fill. Read the label or the instructions that are provided by the OEM of the product.In stationary engine applications that do not require anti-boil protection or freeze protection, a mixture of SCA and water is acceptable. Caterpillar recommends a 6 percent to 8 percent concentration of SCA in those cooling systems. Distilled water or deionized water is preferred. Water which has the recommended properties may be used.

Coolant Service Life
Coolant Type Service Life (1)
Cat ELC 12000 Service Hours or Six Years(2)
Commercial coolant that meets the Caterpillar EC-1 Specification 6000 Service Hours or Six Years(3)
Cat DEAC 3000 Service Hours or Three Years
Commercial Heavy-Duty Coolant/Antifreeze that meets "ASTM D6210" 3000 Service Hours or Two Years
(1) Use the interval that occurs first. The cooling system must also be flushed out at this time.
(2) Cat ELC Extender must be added at 6000 service hours or one half of the service life of the Cat ELC. Refer to your machine Operation and Maintenance Manual for exceptions.
(3) An extender must be added at 3000 service hours or one half of the service life of the coolant.Note: Refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations" for additional information that
