The Safe-Vue washer solvent heater from Rostra Precision Controls works year-round by heating windshield washer solvent to melt ice and snow, remove road oils, tree sap, insects and other dirt or film.
Suitable for use in virtually any vehicle from commercial trucks to passenger vehicles, the patented system automatically heats the solvent in a separate reservoir within 90 seconds of a cold start. The unit is thermostatically controlled to prevent overheating and is insulated to continuously and safely keep the fluid warm, the company says.
Safe-Vue installs in line in the factory washer supply hose that connects the reservoir to the nozzles. The nozzles are mounted at the base of the windshield, in the hood or on the wiper arms. The system also is suitable for headlamp washer systems, and its compact design takes up little space under the hood.
The system retails for $85 and carries a three-year, 36,000-mile warranty.
