      NOTE:
      • Using improper coolants may damage the engine cooling system.

      • New Toyota vehicles are filled with TOYOTA Super Long Life Coolant (pink color, premixed ethylene-glycol concentration is approximately 50% and freezing temperature is -35°C (-31°F)). When replacing coolant, TOYOTA Super Long Life Coolant is recommended.
      • Check the coolant level by pressing the inlet and outlet radiator hoses several times with hand. If the coolant level goes down, add the coolant.
      • Do not substitute water for engine coolant.
