Diagnosing VVT Cam Phaser Issues on Ford 5.4 Liter V8 Engines
In this video from Cloyes, we diagnose timing chain system issues related to VVT cam phasers, or sprockets, on Ford Modular 5.4 liter engines. We also replace the VVT phasers with Cloyes' new VVT phasers, which can be found in Cloyes kit 9-0391SBVVT.
UPDATE: Cloyes has released an updated kit, part number 9-0391SBVVT1, that also includes solenoids.
Ready to replace it?
Find the timing kit that matches the vehicle, or walk through the install procedure with our engineers in the Tech Center.
