Driven Diesel Mechanical Fan Clutch Adapter 03-17 5.9L / 6.7L Dodge Cummins

The factory electronically controlled fan clutch on the Common Rail Cummins is known to have its issues. If you're ready to convert yours over to a good, reliable mechanical fan clutch, its really not that difficult, you just need the right parts, including this specialty adapter and the right fan clutch, in this case, one from an "OBS" Ford, or a 1994-1997 model year Ford, and you're good to go!

This adapter and the associated parts will deliver the reliable cooling solution you are looking for. Check the list below for the necessary parts combinations. In order to use your existing engine fan blade, you must have the 6-Bolt blade assembly (typically found on 03-08 trucks only). If you have the 4-Bolt blade assembly, you will need to purchase the fan blade, as well.

Required Parts For 5.9L Cummins:

• This Cummins Fan Hub Adapter
• 1994-1997 Ford "OBS" Fan Clutch
• Your Stock 6-Bolt Fan Blade

Required Parts Ford 6.7L Cummins:

• This Cummins Fan Hub Adapter
• 1994-1997 Ford "OBS" Fan Clutch
• Your Stock 6-Bolt Fan Blade OR 5.9L Cummins Engine Fan

Notes:

• Removing the Electronic Fan Clutch from your 2003-Current Dodge Cummins Pickup WILL leave an error code in the computer. In our experience, this does not typically trigger the "Check Engine Light", but the soft code will always be present. At this time, we are not aware of any way to disable this code. On some rare occasions on the 6.7 Cummins we have had issues where the A/C will blow warmer due to air flow at idle.
• CUMMINS CONVERSION (COMMON RAIL) CUSTOMERS - Using the stock Dodge Common Rail electronic engine fan in a Cummins conversion project can be a real hassle. Many conversion owners have found that keeping the engine cool with the Dodge electronic fan can be quite challenging. This adapter hub will allow the use of a standard mechanical fan clutch (Ford) and fan on your Common Rail Cummins engine. This eliminates messing around with electronic controls and provides a much more reliable "mechanical" solution to cooling your conversion engine.
• Driven Diesel recommends using the Ford "OBS" Fan Clutch and the Ford 6.0L Fan (23.25" Diameter). While it may be possible to fit the larger Dodge fan (26" Diameter) into some conversions, we CANNOT provide you with information about doing so. It is YOUR RESPONSIBILITY to measure your clearances and order the fan that will best fit your application.
