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.

The 6001Z series from Auto Rod Controls is the latest in control module innovation from ARC! Based on ARC's exclusive flat touch technology this new system is packed with new features that racers not only want but need in an electrical system. This new system incorporates a built-in system kill switch like some of our other units, but to keep the size of the unit down we developed multi-function switches. The water pump and fan are on the same switch. Touch the switch once to turn the water pump on and touch it again to turn on the water pump and the fan. The water pump and fan have separate relays but share one switch. The same holds true for the taillight switch, one touch turns the taillights on the second touch turns out the taillights and turns on the new built in interior lighting which is available in blue or white. Other innovations include ARC's exclusive oil pressure control. The system with monitor the oil pressure through a user chosen pressure switch and if the oil pressure falls below the switch setting it will automatically turn the ignition off. ARC also incorporated a neutral safety into the relay board. Simply connect the supplied wires from the relay board to the neutral safety switch and you are done. The car will not start unless the shifter in in a proper location for starting. This system also has a firewall bump start switch circuit built in. Simply run a supplied wire from the relay board to the bump start switch and ground the switch and your bump start switches are ready for use. These will also work through the neutral safety switch for complete safety. ARC's 6001Z series control modules include printed wire for the car and a user activated ground trigger relay for any use. We also included a dedicated 5-amp data logger circuit which will stay on for 6 seconds after shutting off the ignition to allow for processing. Rounding out this system are 2 30 amp fused power take offs for any use. ARC also includes LED's at every output on the relay board to quickly see if there is power leaving the relay board to the accessory connected to it.
