Fitment Details

Fits 2003 Dodge Ram 2500, N/A. Fits 2003 Dodge Ram 3500, N/A. This part number, 920-2280, is also referenced for the same application under 9202280.

How It Works

The fan clutch helps control engine cooling fan engagement based on temperature, allowing the fan to lock up when cooling demand increases and reduce drag when full airflow is not needed. On Ram 2500 and Ram 3500 trucks, that thermal control supports stable operating temperatures under load and in severe-duty use.

Common Issues It May Address

• Engine running hotter than normal at idle or under load
• Cooling fan not engaging when engine temperature rises
• Excessive fan noise from a clutch that stays engaged too long
• Reduced cooling performance during towing or heavy-duty driving

Installation Notes

Verify reverse-rotation, thermal fan clutch specifications before installation. Confirm the application matches the 2003 Dodge Ram 2500 or 2003 Dodge Ram 3500 and inspect the surrounding cooling system components, including the fan, belt drive, and radiator, before final assembly. Part number 920-2280 should be matched to the vehicle’s original configuration for proper operation.
