Windscreen washer fluid heater for car - has heat exchanger coil tapped into engine coolant circuit using suitable valves

摘要

The windscreen washer fluid reservoir is fitted with a heating coil through which warm coolant is pumped from the engine coolant circuit. The tapped off flow is taken out by breaking into the coolant circuit with simple insert valves. No separate heater is required. The system can be used to warm any fluid tank in the vehicle, including hand wash water for service vehicles. It can be fitted to any vehicle with simple plumbing additions.
