nope. it is supposed to be 100% dry. if it freezes up its usually from the bushing in the clutch swelling up and making the fitment on the shaft be so tight the clutch cant slide back and forth. usually ffrom getting water in the clutches and getting that bushing so hot it swells up and siezes the clutch to the shaft. its time for a new movable sheave when that happens. the bushing is fiber, you cant machine it larger it will trash the whole thing. you cant fix it. you cant replace the bushing. you need a whole new inner movable sheave.
