Do not use a commercial coolant/antifreeze that only meets the ASTM "D3306" specification. This type of coolant/antifreeze is made for light duty automotive applications.Use only the coolant/antifreeze that is recommended.
Note: Caterpillar recommends a 1:1 mixture of water and glycol. This mixture of water and glycol will provide optimum heavy-duty performance as a coolant/antifreeze.Note: Caterpillar DEAC DOES NOT require a treatment with an Supplemental Coolant Additive (SCA) at the initial fill. Commercial heavy-duty coolant/antifreeze that meets "ASTM D4985" or "ASTM D6210" specifications MAY require a treatment with a supplemental coolant additive at the initial fill. Read the label or the instructions that are provided by the OEM of the product.Note: These coolants WILL require a treatment with a supplemental coolant additive on a maintenance basis. Regardless of the ambient temperature, the supplemental coolant additive should be maintained between three to six percent. The Caterpillar 4C-9297 Test Strip can be used to help maintain the appropriate concentration of Caterpillar SCA.
All Caterpillar diesel engines equipped with air-to-air aftercooling (ATAAC) require a minimum of 30 percent glycol to prevent water pump cavitation.
Glycol
For optimum performance, Caterpillar recommends a 1:1 mixture of a water/glycol solution.Note: Use a mixture that will provide protection against the lowest ambient temperature.Note: 100 percent pure glycol will freeze at a temperature of −23 °C (−9 °F).

Concentration Freeze Protection Boil Protection
50 Percent −36 °C (−33 °F) 106 °C (223 °F)
60 Percent −52 °C (−62 °F) 111 °C (232 °F) Check the coolant for the concentration of glycol frequently in cold weather with a refractometer type coolant tester in order to ensure adequate freeze protection.To check the concentration of glycol, use the 1U-7298 Coolant/Battery Tester (DEGREES CELSIUS) or use the 1U-7297 Coolant/Battery Tester (DEGREES FAHRENHEIT). The testers give readings that are immediate and accurate. The testers can be used with ethylene or propylene glycol.Water
Distilled water or deionized water is recommended for use in engine cooling systems. DO NOT use the following types of water in cooling systems: hard water, softened water that has been conditioned with salt, and sea water. Damage to the cooling system may result.
Note: If distilled water or deionized water is not available, use water with the properties that are listed in table 2.
