FAQ:

Q: Is Dexcool really required?

A: DexCool is a required coolant in most all GM vehicles after 1995, if I’m not wrong. But DexCool chemistry behind DexCool is such that it will not harm the environment if there is an accident or leakage. The formula is such that if it is exposed to air, it neutralize itself.

Q: Can Dexcool be mixed with regular antifreeze?

A: AFAIK, all antifreeze solutions can be mixed (same chemical class). The resulting mixture will not harm the cooling system. However, the addition of regular antifreeze to Dex Cool will reduce the long term integrity of the Dex Cool; you have, effectively, reduced the Dex Cool to the change interval of the regular antifreeze.

A: DEX-COOL is a specific type of antifreeze, found in select brands of coolants , created using organic acid technology. The manufacturers as well as General Motors have claimed that DEX-COOL can extend the service life and function of your vehicle.

Q: What color is Dexcool antifreeze?

A: Antifreeze colors include red, orange, yellow, pink, blue and green. Different colored antifreeze is used to identify the type of antifreeze being used. Inorganic Acid Technology (IAT) antifreeze is green in color. Organic Acid Technology ( OAT ) antifreeze is orange, red, green, pink or blue.
