Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Allow the engine to cool before servicing the power steering system.

Symptoms

•Whining or groaning noise when turning the steering wheel
•Increased steering effort or stiffness
•Fluid leakage around the power steering pump or hoses
•Low power steering fluid level
•Steering wheel feels loose or has excessive play

Diagnostic Steps

1
Inspect the power steering fluid level and condition in the reservoir.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Fill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with the recommended power steering fluid if low (Ford specifies Mercon ATF or equivalent).
Check the fluid condition; if it is dark or contaminated, proceed to the next step.

3. Replace Power Steering Fluid

Place a drain pan under the power steering pump.
Disconnect the return line from the pump (ensure you have rags to catch any fluid).
Allow old fluid to drain into the pan.
Reconnect the return line securely.
Fill the reservoir with new power steering fluid until the appropriate level is reached.

4. Inspect and Replace Power Steering Pump (if necessary)

Locate the power steering pump (usually near the engine).
Remove the serpentine belt from the pump using a belt tensioner tool.
Disconnect the power steering lines from the pump (be cautious of residual fluid).
Unbolt the pump from its mounting bracket and remove it.
Install the new power steering pump by reversing the removal steps and ensure all connections are tight.
Reinstall the serpentine belt according to the routing diagram.

5. Bleed the Power Steering System

With the engine off, turn the steering wheel from lock to lock several times to remove air from the system.
Start the engine and allow it to idle while continuing to turn the steering wheel from lock to lock.
Check the fluid level and add fluid as necessary.
