This article supersedes TSB 05-4-4 to update the vehicle model years.
Some 2005-2006 F-Super Duty vehicles, that are NOT equipped with the factory snow plow package, may exhibit an engine overheat condition if a snow plow is installed on the vehicle. The condition typically will occur during normal highway driving. This is due to the snow plow blade disrupting airflow to the engine, causing the cooling fan to stop turning or to spin in reverse.
A new clutch fan (only for snow plow applications) may be installed to correct the condition. Cost of the new clutch fan and its installation is the responsibility of the customer. Refer to Workshop Manual Section 303-03 for removal and installation.
|NOTE:||INSTALLATION OF THIS CLUTCH FAN MAY RESULT IN REDUCED FUEL ECONOMY.|
|NOTE:||FACTORY INSTALLED SNOW PLOW PACKAGE ALSO INCLUDES HEAVIER FRONT SPRINGS, A STEERING DAMPER, AND A 140 AMP GENERATOR.|
