Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Power Steering Fluid

Remove the power steering reservoir cap.
Drain old fluid using a turkey baster or siphon; dispose of it properly.
Refill the reservoir with the manufacturer-recommended power steering fluid.

3. Remove the Old Steering Pump

If leaks are confirmed, locate the steering pump, generally near the front of the engine.
Disconnect the serpentine belt using a belt tensioner tool; note the belt routing for reinstallation.
Disconnect the power steering lines from the pump using a line wrench; be cautious of fluid spillage.
Unbolt the steering pump from the mounting bracket using a socket set (typically 10-15 ft-lbs torque).
Remove the pump from the engine bay.

4. Install the New Steering Pump

Position the new steering pump in place and secure it to the mounting bracket with bolts.
Reconnect the power steering lines, ensuring they are tight to prevent leaks.
Reinstall the serpentine belt according to the routing diagram.
Reconnect the battery.

5. Bleed the Power Steering System

Start the engine and allow it to idle.
Turn the steering wheel fully from lock to lock several times to purge air from the system.
Check the fluid level in the reservoir and top off if necessary.
