F150 Vct Solenoid Screw: What Size Do You Need?

The Variable Camshaft Timing (VCT) solenoid screw size for a Ford F-150 depends on the model year of the vehicle. For example, the 2004 F-150 4x4 5.4L requires a 27 torque head for the VCT bolts, while the 2005 F-150 5.4L 3V uses a T27 hex bit to unscrew the VCT screw. It is important to note that accessing the VCT solenoid on some F-150 models may require removing the valve cover, which can be a challenging task. When performing VCT solenoid replacement, it is crucial to work carefully to avoid dropping any screws or tools into the engine compartment.

VCT solenoid replacement in Ford F150s

The variable valve timing control (VVT or VCT) solenoid in a Ford F-150 is responsible for engaging and disengaging simple variable valve timing systems and constantly adjusting more intricate systems. The VCT solenoid is electrically controlled by the power management computer or the electronic control unit. When the conditions are met, the computer actuates the solenoid, and valve timing is retarded or advanced. Many solenoids accomplish this by directing and limiting oil pressure to the solenoid.

Symptoms of a Bad VCT Solenoid

The most typical symptoms of a variable valve timing control solenoid failure are the check engine light and loss of power. There may also be a leak around the solenoid, but this generally will not cause failure. When the solenoid fails, the driver feels a loss of power because the timing is no longer advancing with engine speed. Another form of failure is when the solenoid advances at all times, leading to rising and falling engine speed at idle, vibrations at idle, and possible misfires at idle. In any case of a failed VCT solenoid, there will be poor fuel mileage until the issue is corrected.

Replacing the VCT Solenoid

Replacing the VCT solenoid switch is very easy on most models and only requires removing the solenoid and moving one electrical connector. The average cost for a Ford F-150 VCT solenoid replacement is between $250 and $305, with labour costs estimated between $157 and $198, and parts priced between $93 and $107. However, some people choose to replace the VCT solenoid themselves to save money.

One person who replaced the VCT solenoids on their 2016 5.0 Ford F-150 reported that the biggest pain was dealing with all the clips that hold the wiring in place and reaching some of the bolts in the back. The tools they needed for the job were a 10mm and 8mm socket, a clip pick, a torch wrench (to put the covers back on), and a clip pry tool. It took them about 6 hours altogether.

Another person who replaced the VCT solenoids on their 2004 Ford F-150 5.4 reported that the job took them about 30 minutes. They did not have to remove the whole power steering bracket, just the reservoir and the side bracket. They also reported that they used gaskets instead of RTV just for added security.

VCT solenoid screw size

The Variable Camshaft Timing (VCT) solenoid screw size for a Ford F-150 depends on the model year of the vehicle. For a 2004 F-150 5.4L 3V, the screw size is a T27 Torx bit. For a 2016 5.0L, the screw is a 10mm socket. For a 2018 3.5L Ecoboost, the intake, valve covers, and then the solenoids need to be removed to access the screws.

The VCT solenoid is part of the Variable Valve Timing (VVT) system, which controls the timing of the engine's valves to optimise performance and fuel economy. The VCT solenoid is a common failure point on the Ford Modular/Triton 4.6L and 5.4L engines, with symptoms including rough idling, stalling, and a "diesel-like" tick from the engine.

Replacing the VCT solenoid on a Ford F-150 is a relatively straightforward process, but care must be taken not to drop the screw into the engine. On some models, the valve cover must be removed to access the solenoid, while on others, it can be accessed without removing the cover. The job typically takes around 30 minutes to two hours for those with some mechanical knowledge and basic tools.

When replacing the VCT solenoid, it is recommended to also replace the valve cover gasket and the solenoid seal. These are available from Ford dealers or aftermarket suppliers and typically cost around $50-150 for a set, depending on the quality and source.

It is important to note that there are different designs of VCT solenoids and that the correct part must be sourced for the specific vehicle. Using an incorrect VCT solenoid can result in poor performance and potential damage to the engine.
