How does the radiator fan work on a Dodge?
This is the Dodge Radiator Fan Wiring Diagram for the traditional version. The powertrain control module (PCM) sends a reference voltage to the engine coolant temperature sensor and monitors the return voltage. When it determines the engine requires cooling, it grounds the control coil in the radiator fan relay.

How many amps does a dual cooling fan need?
With dual cooling fans, there are two methods for wiring up the relay kit. This is based on the draw from the fans, if the fans are larger and draw more than 15 amps each, it’s recommended to install a second relay kit as shown below.
