John Deere Cool-Gard II ready-to-use 50/50 formula protects for so long, some machines get traded in before the coolant needs to be changed. John Deere premium coolants feature high thermal and oxidative stability and corrosion protection while keeping your engine cool. And with a freeze point down to -37°C, they’ll maintain viscosity when it gets cold. They also work great in non-John Deere equipment.
