SUBJECT:
CORRECT COOLANT USAGE
MODEL(S):
XL7 (JC636)
YEAR:

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 XL7, the proper coolant to use is the Ethylene Glycol base Organic Acid type coolant. These vehicles were shipped from the factory with
Dex-Cool(R) in the cooling system, which is orange in color. 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).
CAUTION:
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.
