Ford Water Warning

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.


Turbocharger Service Tips

Turbochargers are essentially compressors that direct more air into the engine’s cylinders in order to produce additional power. A turbo derives its energy source from both temp and pressure of exhaust gas. Intake air enters through the air cleaner into the turbo compressor inlet. The air is compressed which raises air density and volume.


Not So Super Ford Diesel Glitch

Some F-Super Duty F-250/350/450 trucks equipped with a 6.7L diesel engine and built on or before 5/16/2012 may experience an engine shudder with or without turbo flutter noise around 900-1,400 rpm with steady throttle.
