Cooling Components 2-Speed Fan Controllers
Cooling Components 2-speed fan controllers are smart systems offering many advantages over the old school use of relays and temperature sending units. You have the choice of three temperature settings (184/195/205) based on your engine thermostat. They monitor your engine coolant behavior and set the fan start up accordingly, for instance if your engine warms up rapidly the fan would also start sooner. Cooling Components 2-speed fan controllers are weatherproof, so they can be installed anywhere, and installation is way easier than the relay systems. Additional benefits and notes: * Modern, high-quality, all-solid state design * Easy to mount; temperature sensor mounts under thermostat housing bolt * Controls one or two fans/speed * 30+ amp continuous load, 80 amp startup surge * Choice of three temperature settings (185/195/205 degrees) * Sensors to conform with your engine thermostat * A/C request, the fan turns on upon A/C request through a trinary switch * Detects temperature sensor faults, turns on fan for fail-safe operation * Weather-resistant design allows mounting inside or outside the vehicle cabin * Reverse battery, short circuit, and overload protection * 10-32 studs for solid high-current connections * Super compact size, measures only 3.7 in. x 2.6 in. x 1 in.
