Antifreeze
Caterpillar recommends that the coolant mix contain a minimum of 30% Caterpillar Antifreeze, or equivalent and acceptable water to maintain an adequate water pump cavitation temperature for efficient water pump performance.Premix coolant solution to provide protection to the lowest expected outside (ambient) temperature. Pure undiluted antifreeze will freeze at -10°F (-23°C).Only use a greater concentration (above 30%) of Caterpillar Antifreeze as needed for anticipated outside (ambient) temperatures. Do not exceed a coolant mixture of 60% antifreeze to water since a concentration above 60% antifreeze will reduce the engine's freeze protection and increase the possibility of deposit formation in the cooling system.
Use Caterpillar Antifreeze or ASTM D4985-89 (GM Specification 6038-M) Antifreeze. However, supplemental coolant conditioner must be added to these coolants. See topic "Supplemental CoolantAdditive (Conditioner)" in this manual for further information.Caterpillar Antifreeze is available through your Caterpillar dealer in quantities that follow. Most commercial antifreezes are formulated for gasoline engine applications and will, therefore, have high silicate content. Caterpillar Antifreeze is formulated with a low silicate content and the proper coolant additives for heavy duty diesel engines. Caterpillar does not recommend use of high silicate antifreeze in the 3176 engine.ASTM D4985-89 (GM Specification 6038-M) is a low silicate antifreeze, but supplemental coolant additive must be added.The major advantages of Caterpillar Antifreeze are:* Significantly reduces water pump seal leakage problems caused by excessive concentration of chemical additives.* There is no need to add supplemental coolant additive (conditioner) on initial fill, which must be done with current commercially available antifreezes.* High silicate antifreezes used with a supplemental coolant additive can cause a build-up of solids over a period of time which can cause plugging, loss of heat transfer, and water pump seal damage.Make proper antifreeze additions.
Adding pure antifreezes as a makeup solution for cooling system top-off is an unacceptable practice. It increase the concentration of antifreeze in the cooling system which increases the concentration of dissolved solids and undissolved chemical inhibitors in the cooling system. Add antifreeze mixed with acceptable water to the same freeze protection as your cooling system. Pure, undiluted antifreeze will freeze at -10°F (-23°C).Use the chart below to assist in determining the concentration of Caterpillar Antifreeze to use.
5P0957 Coolant Tester (°F) or 5P3514 Coolant Tester (°C)Both are available at your Caterpillar dealer.Check the coolant solution frequently in cold weather for glycol concentration with the 5P0957 or 5P3514 Coolant Tester to ensure adequate protection. Both testers are identical except temperature scale. They give immediate, accurate readings and can be used for antifreeze/coolants that contain ethylene or propylene glycol.If propylene glycol based antifreeze is used, DO NOT allow concentration greater than a 50/50 antifreeze to water mixture. The measurement of freeze protection must be made with a refractive-type tester (Cat 5P0957 or 5P3514) rather than a hydrometer-type, which can be used to test ethylene glycol based antifreeze.Supplemental Coolant Additive (Conditioner)
Supplemental coolant additive (conditioner) is necessary to prevent rust, scale, pitting and/or corrosion of engine parts that coolant comes in contact with. Most antifreeze solutions DO NOT contain sufficient
