Use a 50/50 mixture of clean, drinkable water and DEX-COOL engine coolant. If this mixture is used, nothing else needs to be added. This mixture:

  • Provides freezing protection down to −37 °C outside temperature.
  • Provides boiling protection up to 129 °C engine temperature.
  • Protects against rust and corrosion.
  • Does not harm aluminum components.
  • Helps maintain the correct engine temperature.

Never dispose of engine coolant by putting it in a trash container, pouring it on the ground, or draining it into a sewer, stream, or body of water. Have used coolant replaced by an authorized service center familiar with the laws regarding used coolant disposal. This will help protect the environment and your health.
