Coolant Specifications (continued)
Coolant Type Table
Ethylene-Glycol Coolant Type Corrosion Inhibitor Type
Extended-life antifreeze Organic-acid technology (OAT)
IMPORTANT
Do not rely on the color of the coolant to identify the difference between conventional
(green) inorganic-acid technology (IAT) coolant and extended-life coolant.
Coolant manufacturers may dye extended-life coolant in one of the following colors: red,
pink, orange, yellow, blue, teal, violet, and green. Use coolant that meets the specifications
in the Extended Life Coolant Standards Table.
Extended Life Coolant Standards
ATSM International SAE International
D3306 and D4985 J1034, J814, and 1941
IMPORTANT
Coolant concentration should be a 50/50 mixture of coolant to water.
• Preferred: When mixing coolant from a concentrate, mix it with distilled water.
• Preferred option: If distilled water is not available, use a pre-mix coolant instead of a
concentrate.
• Minimum requirement: If distilled water and pre-mix coolant are not available, mix
concentrated coolant with clean drinkable water.
