Known Problems

A severe lack of power may develop because the hose from the turbocharger to the intake manifold can come loose, resulting in loss of boost pressure to the engine.

The cooler for the EGR valve can leak coolant internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine.

It is common to see the variable vanes inside the turbo seize or bind from carbon buildup. This causes an overboost or underboost condition when driving.

Delamination of the diesel fuel tank can occur resulting in a loss of power due to debris clogging the fuel filters. In some cases the fuel injection pump and/or fuel injectors have also been damaged. Ford has issued a service bulletin (#19728) addressing this concern. This issue can affect all diesel F-350, F-450, F-550, F-650, and F-750 Super Duty models.

Spark plugs in the Ford F-350 Super Duty can be very difficult to remove.

Ford has issued a service bulletin (08-7-6) to address this issue, which includes a recommended procedure on how to remove the plugs. Failure to follow the recommended procedure can result in the one or more spark plugs breaking off in the cylinder head.

The recommend procedure is as follows. Using this procedure will greatly reduce the chance of breaking a spark plug.

1. Break the spark plugs loose when the engine is warm.
2. Turn each plug 1/8 to 1/4 turn and soak the treads with 1/2 to 3/4 teaspoon of Motorcraft Carburetor Tune-Up Cleaner or a quality penetrating oil. Do not try to remove the plugs at this time.
3. Let the threads soak for at least 15 minutes.
4. After the soak period, tighten and loosen each spark plug, working it back and forth until the turning effort is reduced. Then, you can remove the spark plug.

There are special tools available to remove the broken spark plugs and repair shops will often charge additional labor for the removal of each broken spark plug.

The rear sliding glass window may stop working, or binds in motion. The power slider cable binds causing slow, or no operation. The glass assembly will need to be replaced, the cable is included in the assembly.

The high pressure diesel fuel injection pump may fail, resulting in a "no start" condition.

The 2004-2010 Ford F-350 with manual temperature and fan controls may have problems with the the blower motor only blowing air on certain settings. Most commonly the fan will only run on the highest setting. This is a well documented problem, and is caused by a failing blower motor resistor.

Correcting the problem is straight forward, and requires replacement of the small resistor. The resistor is normally found behind the glove box, next to the blower motor.

The VGT solenoid can fail. The VGT solenoid receives signals from the engine control module to adjust the boost that the (variable geometry) turbo is generating. A defective solenoid can also create an overboost or underboost condition when driving.
