The new anti-freeze used for factory installation is an ethylene glycol specification. Please make a note of the material in your library copy for this article.
--------------- END SUPPLEMENT ---------------A new anti-freeze material is used in the engine coolant for factory fill on the listed machines effective April 1994. A forty-four percent concentration of the new anti-freeze is used for factory fill to provide temperature protection to minus 29°C (minus 20°F).
The anti-freeze material that was previously used at factory fill could experience the formation of deposits, if new anti-freeze was added to the listed machines during field maintenance. Refer to the Operation & Maintenance Manual for your specific machine to provide the correct anti-freeze concentration for the ambient temperature protection that is needed.
