This procedure covers removal and installation of the power steering pump pulley on the 2015-2020 Ford F-150 with 3.5L EcoBoost engine. Note: This engine uses Electric Power Assisted Steering (EPAS) with no hydraulic pump or pulley.
Warnings
⚠The 2015-2020 Ford F-150 3.5L EcoBoost uses Electric Power Assisted Steering (EPAS) and does not have a hydraulic power steering pump or pulley. Verify your vehicle configuration before proceeding.
ℹ️If your vehicle has been modified or is equipped with a hydraulic power steering system, consult appropriate service documentation as this procedure does not apply to the factory EPAS configuration.

Preparation
- Verify vehicle steering system type by visually inspecting the engine bay for a hydraulic power steering pump and reservoir
- Consult vehicle service manual to confirm EPAS (Electric Power Assisted Steering) configuration
- If vehicle has hydraulic power steering, obtain correct service procedure for non-EPAS equipped variant
Procedure
- 1Verify Steering System ConfigurationOpen the hood and visually inspect the front of the engine and accessory drive system. The 3.5L EcoBoost in 2015-2020 F-150s uses an electric motor mounted on the steering column or rack, not a belt-driven hydraulic pump. There will be no hydraulic reservoir or pump mounted to the engine. If a hydraulic pump is present, the vehicle may have a different engine or non-factory modification.
- 2Locate Electric Power Steering MotorThe electric power steering motor is located on the steering column inside the vehicle or integrated into the steering rack under the vehicle. It is an electric motor assembly with electrical connectors, not a pulley-driven hydraulic pump. No pulley service is required for this system.
- 3Confirm No Hydraulic ComponentsVerify there is no power steering fluid reservoir, no high-pressure or return lines running from the engine to the steering rack, and no belt-driven pump on the front accessory drive. The EPAS system requires no hydraulic fluid and has no serviceable pulley component.
Reassembly
- No reassembly required as the factory 3.5L EcoBoost F-150 does not have a power steering pump pulley
Verification
- Confirm vehicle has Electric Power Assisted Steering (EPAS) by checking for absence of hydraulic pump, reservoir, and fluid lines
- If steering service is needed on EPAS-equipped vehicles, refer to electric power steering motor, steering column, or steering rack procedures as appropriate
