| We recommend Havoline® Extended Life Anti-Freeze/Coolant DEX-COOL® for all cars and light-duty trucks. The patented long-lasting carboxylate inhibitors in Havoline® Extended Life Anti-Freeze/Coolant DEX-COOL® have proven their long-term performance time and time again against the effects of extreme heat, corrosion and rust. General Motors Corporation has recognized Havoline® Extended Life Anti-Freeze/Coolant DEX-COOL® as a breakthrough coolant, issuing GM's first DEX-COOL® license for 5-year/150,000-mile protection. Extended service intervals are made possible through a patented organic acid corrosion inhibitor system which eliminates the need for silicates, phosphates, borates, nitrites, and amines. The elimination of these additives is significant because many of them are abrasive to water-pump seals.
