freeze type windshield washer fluid. SUBARU Wind-
shield Washer Fluid contains 58.5% methyl alcohol
and 41.5% surfactant, by volume. Its freezing temper-
ature varies according to how much it is diluted, as in-
dicated in the following table.
In order to prevent freezing of washer fluid, check the
freezing temperatures in the table above when adjust-
ing the fluid concentration to the outside temperature.
If you fill the reservoir tank with a fluid with a different
concentration from the one used previously, purge the
old fluid from the piping between the reservoir tank
and washer nozzles by operating the washer for a cer-
tain period of time. Otherwise, if the concentration of
the fluid remaining in the piping is too low for the out-
side temperature, it may freeze and block the nozzles.
Adjust the washer fluid concentration appropri-
ately for the outside temperature. If the concen-
tration is inappropriate, sprayed washer fluid
may freeze on the windshield and obstruct your
view, and the fluid may freeze in the reservoir
tank.
