Using water that meets this requirement may not prevent drop out of these chemical compounds totally but should minimize the rate to acceptable levels.For more information refer to "Know Your Cooling System" Form SEBD0518.Antifreeze Recommendations
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 -23°C (-10°F).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, GM 6038-M or equivalent. Caterpillar Antifreeze is available through your Caterpillar dealer. It is important to use proper coolant to prevent damage to cooling system components. Coolants meeting GM 6038-M (low silicate content) specifications or equivalent may also be used. However, liquid coolant conditioner must be added to these coolants. See section on "Conditioner" in this manual for further information.Most commercial antifreezes are formulated for gasoline engine applications and will, therefore, have high silicate content. Caterpillar antifreeze is formulated with the proper coolant additives for heavy duty diesel engines. Caterpillar Antifreeze (Part No. 8C3686) is available through Caterpillar dealers.The major advantages of Caterpillar Antifreeze are:
* Significantly reduces water pump seal leakage problems due to the over concentration of chemical additives.* There is no need to add coolant inhibitor on initial fill which must be done with current commercially available antifreezes.High silicate antifreezes used with a supplemental coolant conditioner can cause a buildup 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 antifreeze as a makeup solution for cooling system top-off is an unacceptable practice. It increases 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 water to the same freeze protection as your cooling system.*Use lesser amounts of antifreeze.
The reason for the use of ethylene glycol antifreeze is strictly for freeze protection. Use only the amount of antifreeze necessary for the environmental temperature. If operating in warm climates [above 0°C (32°F)], use of plain water treated with a supplemental coolant inhibitor package is sufficient to protect the engine against corrosion and pitting.Caterpillar recommends the use of a coolant mix containing a minimum of 30% Caterpillar Antifreeze and acceptable water. This 30% mixture is necessary to maintain an adequate water pump cavitation temperature for efficient water pump performance. Only use a greater concentration (above 30%) of Caterpillar Antifreeze as needed for anticipated outside (ambient) temperatures. The maximum concentration should not exceed 60% to minimize deposit formations in the cooling system.Use the chart below to assist in determining the concentration
