There are three (3) basic types of coolant available in the market today. Ethylene Glycol base Silicate type coolant, Ethylene Glycol base Phosphate type coolant, and Ethylene Glycol base Organic Acid type coolant. The color of the coolant is only a dye added by the coolant manufacturer and does not indicate coolant type or ingredients. The only way to properly identify the type of coolant is to READ THE LABEL.
For the Aerio, the proper coolant is the Ethylene Glycol base Phosphate type coolant. The proper vehicle coolant system mix is 50/50 coolant to water*
*It is strongly recommended that either distilled water is used to mix with concentrated coolant or a "pre-mixed" coolant is used. This is especially important in areas where the tap water has a high concentration of dissolved minerals (Hard Water). An extremely high amount of dissolved minerals may cause the Silicates or Phosphates to drop out of suspension and cause cooling system malfunction (i.e. rapid seal wear, block corrosion, passage way and/or radiator blockage).
WARNING:
DO NOT MIX DIFFERENT TYPES OF COOLANTS. MIXING DIFFERENT COOLANTS MAY RESULT IN ACCELERATED SEAL WEAR AND/OR THE POSSIBILITY OF SEVERE OVERHEATING AND EXTENSIVE ENGINE/AUTOMATIC TRANSMISSION DAMAGE.
