  • Device to provide heated washer fluid
    Patent number: 6364010
    Abstract: An apparatus and method for improving the cleaning and deicing effectiveness of a washer fluid in a motor vehicle before spraying it against a windshield, headlamps, etc., utilizes the heat from the engine coolant to elevate the temperature of the washer fluid. In addition, a mixing valve arrangement is used to maintain the temperature of the heated washer fluid at a predetermined difference value from that of the windshield, etc., outside surface. The cleaning effectiveness of the heated washer fluid is superior to that of ambient temperature washer fluid, and is also advantageous for deicing purposes.
