           To drain water from the water separator:
           (1) Place a drain pan or dry cloth under the
              water separator.
           (2) Gradually loosen the drain screw to drain
              the water. Catch the draining water in the
              drain pan or soak it up with the dry cloth
              so that it does not spill into the engine
              compartment. If any water spills into the
