Caspers Electronics Hi-Lo Fan Controllers

Caspers Electronics' new-design plug and play Hi-Lo fan controllers install easily on the PWM-controlled coolant fan found on C6 Corvettes. The factory coolant fan is powerful and incorporates a solid-state controller instead of relays (as in previous years and models). These Hi-Lo fan controllers interface with the factory controllers and permit manual coolant fan control. Caspers Electronics Hi-Lo fan controllers simply plug into the fan connector and include a round rocker switch that matches similar design control switches found in the console. Using this switch allows the vehicle operator to manually override the ECU control of the coolant fan to force-cool the engine, even when the car is unattended and not running. These control modules are designed to be plugged in between the sealed fan connector and its mate. These modules are completely sealed from moisture and contaminants and incorporate three sealed connectors. Caspers Electronics Hi-Lo fan controllers require a 20mm mounting hole to be drilled and have three switch positions--Low, which is half-speed fan control, Normal, which is controlled by the car's ECU, and High, which is maximum coolant fan speed. This gives the driver complete control over engine cooling. The switch can override fan control unattended, even with no key in the ignition. Show Less
