Driven Diesel DD-FFCS Fan Clutch Accelerator Switch

offers the Driven Diesel DD-FFCS Fan Clutch Accelerator Switch that allows you to control the fan clutch in your 2003-2007 Ford 6.0L Powerstroke. The Fan Clutch Accelerator Switch will allow you to manually control the electronic engine fan clutch in your truck. When engaged, this device will cause your ECM to think that your Engine Coolant Temperature has risen, causing your ECM to command more fan speed from the clutch. When disengaged, the ECM will see the correct temperature from the coolant temperature sensor and operate the fan as normal.

The Driven Diesel Fan Clutch Accelerator Switch is engineered to be used "AS NEEDED" and should not be enabled full-time. Leaving this device engaged all the time will cause the engine fan to run excessively, causing more engine noise, decrease fuel economy, and reduced power. If you have experienced situations where coolant and oil temperatures increase, but you aren't hearing your fan engage to aid in cooling, this is the reason why.
