2007 Ford F-250 Super Duty Problems
RepairPal has identified the most common problems with the 2007 Ford F-250 Super Duty based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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 Ford F-250 Super Duty has known issues with the V8 engine ejecting spark plugs. This will make a tapping or knocking noise, plus the engine will begin to misfire at all speeds. The check engine light will also illuminate.
The threads on the cylinder head are too short and soft, allowing pressure from combustion to overwhelm and destroy the threads.
When the spark plug ejects, the cylinder head becomes damaged, necessitating repair of the spark plug port threads, or replacement of the cylinder head and cylinder head gasket.
Ford has recommended a method of repair for the cylinder head that prevents the spark plug from ejecting under future use. Replacement of all spark plugs is not necessary, but an updated spark plug design can help prevent this from happening in the future.
There is a technical service bulletin for the V8 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.
Spark plugs in the Ford F-250 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 high pressure diesel fuel injection pump may fail, resulting in a "no start" condition.
The 2004-2010 Ford F-250 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 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.
A defective driveshaft can cause a drone to be heard from the driveline area. The driveshaft should be replaced with a revised unit.
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.
