- Electric fan: driven by the vehicle's electrical system, more efficient and quieter
Fan configuration and design
- Single fan configuration: suitable for low speed operation
- Dual fan configuration: improves cooling efficiency, suitable for high-speed driving
Size and compatibility
- Measure the distance between the radiator and engine components
- Make sure the fan covers as much radiator space as possible
CFM rating and power consumption
- Choose a fan that matches the vehicle's engine size and power
- Consider the power consumption of electric fans
Installation and maintenance
- Check fuses for safety
- Check fan operation regularly
Cost and performance
- OEM fans: high price but guaranteed matching and performance
- Aftermarket fans: low cost, high reliability
