ABSTRACT OF THE DISCLOSURE An apparatus is provided for warming the window washing liquid of a motor vehicle having a window washing system, which includes a window washer liquid tank, a washer liquid pump, washer liquid hoses and window nozzles. The apparatus includes an exposed, flexible tube having a generally circular cross- sectional shape, helically wound about, and extended axially along, and at least partially elastically held to, an outer surface of an engine coolant circulatory hose connected between the outlet of the cooling jacket of an engine of the motor vehicle and the inlet to a radiator of the engine by being wound about the engine coolant circulator hose under tension; and coupling means at each end of the exposed flexible tube for connecting the heat exchanger means between the washer liquid tank and the washer liquid hose through which washer liquid flows from the tank to the washer liquid ejecting window nozzles. This apparatus is simple, inexpensive and can easily be installed. The apparatus needs little space, because it is installed by winding the flexible heat exchanger tube under tension around the engine coolant circulatory hose. It also solves the difficulty of securement of parts, which has been a serious problem in the past by the combination of winding the flexible heat exchanger tube under tension around the engine coolant circulatory hose, and the use of a preferred specifically recited additional securing means.
