Power Steering Hose - High Pressure

This procedure replaces the high-pressure power steering hose on a 2015-2020 Ford F-150 with the 3.5L EcoBoost engine. Note that these vehicles use Electric Power Assisted Steering (EPAS) and do not have a traditional hydraulic power steering system with a high-pressure hose.

Warnings

Tools required

Preparation

1. Verify that your vehicle actually has a hydraulic power steering system before proceeding
2. Consult your vehicle's owner manual or check under the hood for a power steering fluid reservoir - EPAS-equipped vehicles will not have one
3. If you have confirmed your vehicle has hydraulic power steering (non-standard configuration), obtain the correct replacement hose before beginning work

Procedure

1. 1

   Verify steering system type
   Open the hood and look for a power steering fluid reservoir on the passenger side of the engine bay. The 3.5L EcoBoost F-150 uses Electric Power Assisted Steering (EPAS) and will not have a reservoir, pump, or hydraulic hoses. If no reservoir is present, this repair does not apply to your vehicle.
2. 2

   Identify actual steering concern
   If experiencing steering issues on an EPAS-equipped vehicle, the problem is likely related to the electric steering motor (located on the steering column), wiring harness connections, steering angle sensor, or the power steering control module. Use a diagnostic scan tool to check for power steering fault codes.
3. 3

   Consult alternative repair procedures
   For EPAS-equipped vehicles, refer to electric power steering motor replacement, steering column service, or electronic diagnostic procedures instead of hydraulic hose replacement. The electric motor is mounted on the steering column inside the vehicle.

Reassembly

1. This procedure does not apply to the specified vehicle configuration
2. No reassembly steps are required as no disassembly should have occurred

Verification

• Confirm your vehicle's steering system type by checking the owner's manual or looking for the absence of a power steering fluid reservoir
• If you have steering concerns, verify proper operation of the electric power steering system using a diagnostic scan tool
• Ensure no fault codes are present in the power steering control module
