Its freezing tem- perature varies according to how much it is diluted, as indicated in the following table. Washer Fluid Con- centration Freezing Temperature 30% 10.48F (−128C) 50% −48F (−208C) 100% −498F (−458C) In order to prevent freezing of washer fluid, check the freezing temperatures in the table above when adjusting the fluid concentration to the outside temperature.
