Coolant Specifications
Use a mixture of water, ethylene glycol (antifreeze) and cooling system conditioner. Pure, undiluted antifreeze will freeze at -23°C (-10°F).Do not use Caterpillar liquid cooling system conditioner or coolant conditioner elements with Dowtherm 209 Full-Fill coolant. Follow the instructions provided with the Dowtherm 209 Full-Fill coolant.
Refer to "Know Your Cooling System," Form SEBD0518, for more detailed specifications.Water
Acceptable water for use in the ethylene glycol and water mixture is shown in the chart below: Antifreeze
Use the correct amount of ethylene glycol mixed with water, to provide freeze protection to the lowest expected outside temperature.Conditioner
Always add liquid cooling system conditioner to water, or install a coolant conditioner element (if equipped). Never use water only.Never use both liquid cooling system conditioner and a coolant conditioner element (if equipped) at the same time.
Use Caterpillar liquid cooling system conditioner or a coolant conditioner element (if equipped). This will provide a 3% to 6% concentration of conditioner in the cooling system to help prevent corrosion.Conditioner can be purchased from your Caterpillar dealer.Fuel Specifications and Information
Types of Fuel
Caterpillar diesel engines have the ability to burn a wide variety of fuels. These fuels are divided into two general groups, preferred and permissible.The preferred fuels provide maximum engine service life and performance. They are distillate fuels. They are commonly called diesel fuel, furnace oil, gas oil or kerosene.The permissible fuels are crude oils or blended fuels. Use of these fuels can result in higher maintenance costs and reduced engine service life.Refer to "Fuels for Caterpillar Diesel Engines," Form SEHS7067, for a detailed summary of preferred and permissible fuels and their specifications.Refer to S.A.E. J313 Diesel Fuels for information about better quality fuels, such as ignition quality, gravity/density, viscosity, cloud point, sulfur content, etc.Fuel Sulfur Content
The percentage of sulfur in the fuel will affect the engine oil recommendations (see "Engine Oils" under "Lubricant Specifications).Fuel sulfur is chemically changed during combustion to form sulfuric acid. The acid chemically attacks metal surfaces and causes corrosive wear. Higher engine oil TBN values are essential to minimize corrosive wear.Periodically request fuel sulfur content information from your fuel supplier. Fuel sulfur content can change with each bulk delivery.Fuel Cetane Requirement
The minimum fuel cetane number recommended for the direct injection engine is 40.Fuel Cloud Point
Fuel waxing can plug the fuel filters in cold weather. The fuel cloud point must be below the temperature of the surrounding air to prevent filter waxing and power loss. Fuel heating attachments are available from your Caterpillar dealer to minimize fuel filter waxing.Lubricant Specifications
The abbreviations listed below follow S.A.E. J754 nomenclature. The classifications follow S.A.E. J183 classifications. The MIL specifications are U.S.A. Military Specifications. These definitions will be of assistance in purchasing lubricants. The recommended oil viscosities are found on the "Recommended Lubricant Viscosities" chart.The prefix "SPC" is a general abbreviation used by Caterpillar to identify special oils such as synthetic or semi-synthetic oils.Engine Oils (CD or CD/TO-2)
Use oils that meet the Engine Service Classification CD (MIL-L-2104D) or oils that have satisfactory performance in the Caterpillar Oil Test
