* Electric fans. Electric fans are typically mounted on the front of the radiator and have a plastic shroud. They are powered by an electric motor that is mounted on the fan assembly. Electric fans are often used in vehicles with smaller engines or in vehicles that do not require a lot of cooling.
* Motor-driven fans. Motor-driven fans are typically mounted on the water pump and are driven by a belt that is connected to the engine. Motor-driven fans are often used in vehicles with larger engines or in vehicles that require a lot of cooling.
Here are some additional tips for telling if a radiator fan is electric or motor driven:
* Electric fans usually have a wiring harness that connects them to the vehicle's electrical system. Motor-driven fans do not have a wiring harness.
* Electric fans are typically quieter than motor-driven fans. Motor-driven fans can be quite noisy, especially when they are running at high speeds.
* Electric fans can be turned on and off independently of the engine. Motor-driven fans are always running when the engine is running.
If you are still not sure whether a radiator fan is electric or motor driven, you can consult your vehicle's owner's manual. The owner's manual will contain information about the type of fan that is used in your vehicle.
