Safety Warning: Disconnect the battery before working on electrical components.

2. Address Power Steering Pump Issue

Check Fluid Level:
- Remove the power steering cap and check fluid level; top off with the manufacturer-recommended fluid if low.
Replace Power Steering Pump (if faulty):
- Disconnect Battery: Prevent electrical shorts.
- Remove Serpentine Belt: Loosen tensioner and slide the belt off the power steering pump pulley.
- Unbolt Pump: Use socket set to remove the mounting bolts and detach the pump from its bracket.
- Disconnect Hoses: Carefully detach the high-pressure and return hoses, allowing fluid to drain.
- Install New Pump: Position the new pump and secure it with mounting bolts (torque to manufacturer specifications).
- Reconnect Hoses: Attach the high-pressure and return hoses ensuring no leaks.
- Reinstall Serpentine Belt: Follow the belt routing diagram and ensure proper tension.

3. Replace Alternator (if necessary)

Remove Belt: Repeat steps from above to remove the serpentine belt from the alternator.
Unbolt Alternator: Remove bolts securing the alternator and disconnect the electrical connectors.
Install New Alternator: Position the new alternator, secure it with bolts (torque to specifications), and reconnect wiring.
Reinstall Belt: Ensure it is properly seated in all pulleys.
