Disconnect the negative battery terminal to prevent electrical shock.
Raise the front of the vehicle and secure it on jack stands for better access.

2. Remove the Serpentine Belt

Use a ratchet and socket to relieve tension on the serpentine belt tensioner.
Carefully slide the belt off the power steering pump pulley and note the routing for reinstallation.

3. Remove Power Steering Pump

Disconnect the power steering fluid reservoir from the pump.
- Remove the hose clamp using pliers and slide the hose off.
Unbolt the power steering pump from its mounting bracket using a socket set.
Carefully lift the pump out of its mounting location and detach any electrical connectors.

4. Install New Power Steering Pump

Position the new power steering pump in place and secure it with the mounting bolts. Torque the bolts to the manufacturer's specification (consult service manual for exact torque values).
Reconnect the electrical connectors if applicable.

5. Reconnect Power Steering Hoses

Attach the power steering fluid reservoir hose to the new pump and secure it with the hose clamp.
Ensure all connections are tight and leak-free.

6. Reinstall Serpentine Belt

Refer to the noted routing and place the serpentine belt back onto the power steering pump pulley.
Use the ratchet to apply tension to the belt tensioner and ensure the belt is properly seated on all pulleys.
