Abstract: A washer fluid system including a reservoir having a discharge for transferring fluid through a transfer hose via at least one discharge nozzle aligned to discharge the fluid onto a windshield of the vehicle. The device includes a housing having an inlet to receive fluid from the transfer hose at a point downstream from a discharge motor and an outlet to discharge fluid to the transfer hose for discharge by the nozzle. Fluid is held by a container operably connected to the inlet and the outlet. A heating element, preferably powered by the vehicle's electrical system, most preferably only when the ignition for the vehicle is in the on position, heats fluid in the container to a temperature which does not exceed a predetermined maximum temperature such as 50.degree. F. above ambient temperature. Insulation is provided for insulating the container in the housing.
