E46 cooling fan relay location.

Just showing the location of the relay box under the hood on the e46. On all bmw models up through the late 90s the auxiliary or main fan is controlled by one or two thermostatic switches that are mounted into the radiator side or bottom tanks. These cooling fans rely upon electric motor and they typically have a moderate to high slow draw which means that they are commonly controlled with a relay that relay controls the fans for the engine. Almost all modern vehicles rely upon electric cooling fans to pull air through the vehicle radiator to keep the engine cool.

There is no engine driven mechanical fan. It is a rectangular box with wires going to a harness and two wires going to the fan motor. The aux fan relay is located on the fan shroud on e46 vehicles.
