The Prestone Command Supplemental Coolant Additive protects coolant systems from corrosion and prevents buildup of harmful deposits. It controls the pH balance with chemical conditioning. The SCA will prevent rust and buildup, protect cooling system components and replenish corrosion inhibitors.

The Extender Liquid Coolant Additive is a corrosion inhibitor recharge for heavy duty cooling systems. It is specifically designed for extended service intervals. The additive will inhibit rust, corrosion and scale formation and protect cooling system metals. It also provides wet liner protection.

“These products provide vital protection for heavy duty engines while complimenting the Prestone Command line,” said Mike Henning, Prestone marketing manager for heavy duty. “The addition of Supplemental Coolant Additives and Extender Liquid Coolant Additive to our product line demonstrates our continued commitment to the heavy duty market.”
