Cummins Fan Clutches
Cummins fan clutches regulate cooling fan operation in diesel engine cooling systems, helping maintain proper engine temperature under varying load conditions. These components engage the engine fan when additional airflow is required and disengage it when cooling demand decreases. At Advanced Truck Parts, we supply Cummins fan clutches designed for reliable performance in heavy-duty diesel engines.

Cummins Fan Clutches in Diesel Cooling Systems
Fan clutches control when the engine cooling fan engages. By activating the fan only when necessary, the system helps reduce engine load, improve fuel efficiency, and maintain consistent operating temperatures.
Cummins fan clutches help manage:
- Cooling fan engagement and disengagement
- Engine temperature regulation
- Cooling system airflow management
- Reduced parasitic engine load
- Improved fuel economy and efficiency
Proper fan clutch operation is essential for maintaining stable engine temperatures, especially during heavy hauling, long climbs, or high ambient temperature conditions.
Common Cummins Engine Applications
Cummins fan clutches are widely used across heavy-duty and medium-duty diesel engine platforms.
- Cummins ISX CM870, CM871, CM2250, CM2350
- Cummins X15 Performance and Efficiency Series
- Cummins ISB 6.7L engines
- Cummins ISC and ISL engines
- Kenworth, Peterbilt, Freightliner, and International trucks
Depending on the engine and vehicle configuration, fan clutches may be electronically controlled, viscous, or air-actuated.
Common Fan Clutch Failure Symptoms
- Engine overheating
- Cooling fan not engaging when required
- Cooling fan running constantly
- Excessive fan noise
- Reduced cooling system efficiency
Fan clutch failures may occur due to internal wear, bearing failure, electrical control issues, or air system faults depending on the clutch design.
Verify Fitment Before You Buy
Fan clutches vary depending on engine model, cooling system configuration, and truck platform. To confirm compatibility before ordering, provide:
- Engine serial number
- Truck year / make / model
- Current fan clutch part number
- Photos of the fan clutch or identification label if available
This information helps ensure the correct Cummins fan clutch is selected for your application.
