Coolant Specifications
Use a mixture of water, antifreeze and cooling system conditioner. Pure, undiluted antifreeze will freeze at -23°C (-10°F).Always add cooling system conditioner to water, or install a coolant conditioner element (if equipped). Never use water only.To prevent over inhibiting the cooling system, never use both liquid cooling system conditioner and a coolant conditioner element (if equipped) at the same time.Do not use Caterpillar 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 and instructions on water and cooling system conditioner sampling and testing.Water
Acceptable water for use in the ethylene glycol-type antifreeze and water mixture is shown in the chart below: Antifreeze
Use ethylene glycol-type antifreeze. Use the correct amount, mixed with water, to provide freeze protection to the lowest expected outside temperature.Cooling System Conditioner (Liquid)
Use Caterpillar cooling system conditioner or equivalent. Add the correct amount of cooling system conditioner at every oil change interval to maintain a 3% to 6% concentration. Conditioner can be purchased from your Caterpillar dealer.Coolant Conditioner Elements (If Equipped)
Coolant conditioner elements should be used to maintain a 3% to 6% concentration of conditioner. Install a new maintenance element at every oil change interval. Use a precharge element when filling the complete system or changing coolant. Your Caterpillar dealer can provide you with the correct coolant conditioner element.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 acids. 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
