Overview
Zerex® DEX-COOL is GM approved for use in GM vehicles produced beginning in 1996. This formula also meets many of the European manufacturers' phosphate-free and Asian manufacturers' silicate-free requirements.
For convenience and protection try Zerex® DEX-COOL Ready To Use. Zerex® DEX-COOL Ready To Use combines the excellent temperature and corrosion protection of Zerex® DEX-COOL with de-mineralized water to help reduce the risk of cooling system deposits. The 50/50 mixture provides protection down to -34°F.
How It Works: Zerex DEX-Cool uses the highest quality virgin ethylene glycol for freeze and boilover protection and a patented organic acid corrosion inhibitor package to provide extended engine protection against rust and corrosion.
How To Use
Due to the differences in cooling systems, Valvoline recommends that you refer to your vehicle owner's manual for instructions on changing your antifreeze.
