Coolant
These recommendations are subject to change without prior notice. Contact your Caterpillar dealer for the most up to date recommendations.
Never add coolant to an overheated engine. Engine damage could result. Allow the engine to cool first.
Frequently check the specific gravity of the coolant for proper freeze protection or for anti-boil protection.
Never operate an engine without water temperature regulators in the cooling system. Water temperature regulators help to maintain the engine coolant at the proper operating temperature. Cooling system problems can develop without water temperature regulators.
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 Engine Coolant -1 (EC-1) specification.Acceptable - Cat DEAC (Diesel Engine Antifreeze/Coolant) or a commercial heavy-duty coolant that meets "ASTM D4985", or "ASTM D6210" specificationsNote: Cat DEAC does not require a treatment with a Supplemental Coolant Additive (SCA) at the initial fill. However, a commercial heavy-duty coolant that only meets the "ASTM D4985" specification will require a treatment with an SCA at the initial fill. A commercial heavy-duty coolant that meets the "ASTM D6210" specification will not require a treatment with an SCA at the initial fill. Read the label or the instructions that are provided by the manufacturer of the commercial heavy-duty coolant.Note: These coolants will require a treatment with a supplemental coolant additive on a maintenance basis.

Service Life Before Flushing and Before Refilling
Coolant Service Life(1)
Cat ELC 965,606 kilometers (600,000 miles), 12,000 hours, or 6 years
Commercial coolant that meets the Caterpillar EC-1 specification 482,803 kilometers (300,000 miles), 6000 hours, or 6 years
Cat DEAC 321,869 kilometers (200,000 miles), 3000 hours, or 3 years
Commercial Heavy-Duty Coolant that meets "ASTM D4985" or "ASTM D6210" 241,402 kilometers (150,000 miles), 3000 hours, or 1 year
(1) Use the interval that occurs first.Note: Add the Cat ELC Extender at the halfway point of the coolant change interval.Note: These coolant change intervals are only possible with annual S O S Services Level 2 coolant sampling and analysis.S O S Services Coolant Analysis

Recommended Interval
Type of Coolant Level 1 Level 2
DEAC Every 250 Hours(1)
(2) Yearly(1)(3)
ELC Optional(3) Yearly(3)
(1) This is the recommended interval for the sampling of all conventional heavy-duty coolant.
(2) This is also the recommended interval for the sampling of a commercial coolant that meets the Cat (Engine Coolant specification - 1) requirement.
(3) The Level 2 coolant analysis should be performed sooner if a problem is suspected or identified.Testing the engine coolant is important to ensure that the engine is protected from internal cavitation and from corrosion. The analysis also tests the ability of the coolant to protect the engine from boiling and from freezing. The S O S Coolant Analysis can be performed at your Caterpillar dealer. Caterpillar S O S Coolant Analysis is the best way to monitor the condition of your coolant and your cooling system. S O S Coolant Analysis is a program that is based on periodic samples.
Always use a designated pump for oil sampling, and use a separate designated
