Electric Cooling Fan Shutdown

This cooling fan shutdown set from Ron Francis Wiring shuts down your electric cooling fan above 50-60 MPH to improve engine cooling by preventing the electric fan from fighting airflow through the radiator at highway speeds.

In vehicle testing, a ten degree drop in engine temperatures while operating above 60 MPH was seen. The unit is adjustable and may be overridden by using the supplied dash mounted toggle switch.

Important: This kit is designed to be used with the supplied signal generator which must be installed into the speedometer cable.
