Wiring Diagram for the Radiator Fan

Model: (Various brands) Various
Part: Checks and maintenance

Here we see a wiring diagram for the radiator fan, which varies slightly depending on the car model, but the basic principle is similar for most vehicles. The fan receives power from the battery through a dedicated fuse, and the circuit is controlled by one or two relays (for low/high speed). The low speed is activated by the temperature sensor when the coolant reaches a certain threshold: the relay closes the circuit with a resistor in series to reduce the speed. The high speed is activated at higher temperatures (above 100°C) or when the air conditioning is on. The relay bypasses the resistor, powering the fan at full capacity. The fan is connected to ground to complete the circuit.
