Coolant Specifications (continued)
Coolant Type Table
Ethylene-Glycol Coolant Type
Extended-life antifreeze
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

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.
