This is the system that provides heated washer fluid to quickly remove frost and ice from a windshield. The unit connects to the car battery and the washer fluid reservoir and its internal heat chamber warms the washer fluid to between 143º F and 150º F in 30 seconds. The heated fluid instantly melts ice (eliminating the need to scrape the windshield), helps clear frozen spray nozzles, and releases wiper blades that are stuck because of ice or snow. When driving, the heated fluid removes ice from wiper blades and arms and prevents it from building up. The unit draws on average only 2 Amps-less than 1% of a typical car battery and automatically shuts off when the engine is turned off. In warm months, the heated fluid removes insects, road grime, and tree sap more effectively than cool fluid. Works with any washer fluid. 5 1/2" H x 4" W x 1 3/4" D. (1 lb.)
