Same with my dad's old Model A I drove to high school and JC. When the 
wipers 'worked,' they didn't do shit anyways (but they worked better 
than the mechanical brakes). Funny, even some modern cars haven't solved 
the 'Wiper Mystery' completely (but I don't have any of the high-priced 
marques, maybe they work better and yes, I've tried the fancy bladed, 
silicone wipers and other blades).

                  <div>Just remember that the cooling system is meant to
                    work in balance, so increasing the water flow
                    through the system often may not actually reduce
                    temperatures, since the water must flow through the
                    radiator slowly enough to cool down.  If you push
                    water through the radiator too fast, you might just
                    end up recycling hot water back into a hot engine. 
                    So if you put a pump on the car, I would put a
                    supplementary tandem pump, not one that is meant to
