Disconnect the negative battery terminal to ensure safety.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick or markings.
If low, add the recommended power steering fluid (usually ATF or a specific power steering fluid) until it reaches the correct level.

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

Tools Required: Socket set, torque wrench, power steering pulley puller, fluid catch basin.
Sub-steps:
1. Remove any accessories or components obstructing access to the power steering pump.
2. Use the power steering pulley puller to remove the pulley from the pump.
3. Disconnect the power steering lines from the pump using a wrench (be prepared for fluid spillage).
4. Unscrew the bolts securing the pump to the engine and remove the pump.
5. Install the new power steering pump by reversing the removal steps, ensuring to tighten bolts to the manufacturer's torque specifications.

4. Check and Replace Drive Belt (if necessary)

Tools Required: Socket set.
Sub-steps:
1. Inspect the drive belt for cracks, fraying, or signs of wear.
2. If damaged, loosen the tensioner and remove the old belt.
3. Route the new drive belt according to the belt routing diagram.
4. Tighten the tensioner to ensure proper belt tension.

5. Refill and Bleed the Power Steering System

Tools Required: Funnel.
Sub-steps:
1. Refill the power steering fluid reservoir to the recommended level.
2. Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
3. Check the fluid level again and add more if necessary.
