[s-cars] RE: Winterizing Windshield Washer Fluid

[Doyt W. Echelberger]

I'll bet the water molecules at the surface in the reservoir evaporated 
(left the surface, broke away from the alcohol) when the reservoir got 
warmed by the engine heat. The water vapor filled the delivery tubes and 
kept getting pushed out toward the end of the nozzle by the energy from the 
warm engine....so when the pure distilled water vapor condensed in the cold 
delivery tube and nozzle...it became a frozen plug.
