2. Check and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir (typically near the front of the engine compartment).
2. Remove the cap and check the fluid level; if low, top it off with the manufacturer-recommended fluid.
3. If the fluid is dark or contaminated, drain the old fluid into a catch pan.
4. Refill with new power steering fluid to the appropriate level.

2. Disconnect the fluid lines from the pump using the appropriate wrench; be prepared for some fluid spillage.
3. Install the new power steering pump by reversing the removal steps, ensuring all connections are tight.
4. Torque the mounting bolts to the manufacturer’s specifications (consult service manual for exact torque values).

4. Reconnect Battery and Test

Sub-steps:
1. Reconnect the battery terminals securely.
2. Start the vehicle and turn the steering wheel from lock to lock to circulate the fluid and remove any air bubbles.
3. Monitor for any unusual noises or leaks from the pump area.
