Remove the two obvious screws from the top and filler neck. There are two more screws in the front of the reservoir that fit into recesses that are molded into the reservoir. That is why the reservoir seems loose but still will not come out. To access these screws, remove the turn signal\parking light assembly by removing 4 Phillips head screws. Use a light to help you see two 1/2" head bolts recessed in between panels of sheet metal. One is right at the top edge of the opening so you may have to shine your light slightly upwards.
