Ford cautions about the use of tap water when final flushing the cooling system of a 6.0L or 6.4L diesel engine in 2003-2010 F-Super Duty trucks. The use of tap water in some geographic areas can lead to unacceptable scaling and/or corrosion within the cooling system (water jackets/passages) as well as decreased coolant pump life.
Some 2008-2010 Ford F-Super Duty 250-550 trucks equipped with a 6.4L diesel engine may exhibit a random engine ticking/tapping noise that is most noticeable when engine coolant temperature is 185 degrees Fahrenheit or higher, and from base idle to about 1,500 rpm. Some customers may complain that this noise becomes more evident after 3,000 t9o 5,000 miles after an engine oil change.
Some 2008-2010 Ford F-Super Duty trucks equipped with a 5.4L engine may exhibit a MIL on with DTC P2135. Various other DTCs may also be present. Symptoms may include intermittent rough idle, idle speed below specification and/or reduced power.
Some 2011-2014 Ford F-Super Duty vehicles equipped with a 6.7L diesel engine may exhibit an illuminated MIL and DTC P2043 (fault in the DEF reductant heater assembly).
Some 2011-2014 Ford F-Super Duty trucks equipped with a 6.7L diesel engine that are primarily used in a stationary or off-highway use may exhibit frequent exhaust regeneration attempts. Drive To Clean messages and/or the wrench light on may appear, with DTC P2463 for a restricted diesel particulate filter (DPF).
Some 2011-2012 Ford F-Super Duty vehicles equipped with a non-power take-off (PTO) automatic transmission may exhibit high shift efforts due to mud or snow packing around the transmission shift lever area. This is typically found on vehicles operating in extreme mud or snow environments, allowing debris to accumulate on underbody components.
Some 2008-2010 Ford F-Super Duty 250-550 trucks equipped with a 6.4L diesel engine may exhibit a lack of power with an intermittent DTC P0088 at full operating temperature during moderate to heavy acceleration. A calibration update is available to resolve the concern.
Some 2011-2014 Ford F-Super Duty trucks equipped with a 6.7L diesel engine may exhibit an illuminated MIL and DTC P2043. This DTC sets due to a fault in the reductant heater assembly.
Some 2011-2012 Ford F-Super Duty vehicles equipped with the 6.7L diesel engine may exhibit a Stop Safely Now instrument cluster message with the MIL on, with DTCs P200E and P200C.
Some 2008-2010 Ford F-Super Duty trucks equipped with the 6.4L engine and built on or before 11-1-2009 may exhibit a DTC P040D related to the EGR sensor located in the right-hand turbocharger inlet pipe.
