The Driven Diesel Fan Clutch Accelerator Switch for 04-07 5.9L MANUAL TRANSMISSION Dodge Cummins AND 07-20 6.7L AUTO OR MANUAL TRANSMISSION Dodge Cummins trucks will give you some manual control of your electronic engine fan clutch. When enabled, the Fan Clutch Accelerator will cause your ECM to think that your Engine Coolant Temperature has increased, thereby causing your ECM to command more fan speed from the clutch. When disabled, the ECM will see the correct temperature from the coolant temperature sensor, and operate the fan normally.

DOES NOT WORK ON 04-07 AUTOMATIC TRANSMISSION TRUCKS!

This product is designed to be used "AS NEEDED", leaving it enabled all the time will result in running the engine fan excessively, causing more engine noise, lower fuel economy and a reduction in power. If you have experienced situations where your truck and load are causing coolant and oil temperatures to rise, but you aren't hearing your fan engage to aid in cooling, this is your answer.

NOTE: When enabled, your dash gauge and/or digital monitor will reflect a higher than actual Engine Coolant Temperature. In order to see the actual coolant temperature, the Fan Clutch Accelerator must be in the OFF position.

Also, the installation and use of the Fan Clutch Accelerator Switch WILL NOT resolve problems with a weak or worn out fan clutch. Proper performance of this product requires a correctly functioning fan clutch.
