Ensure the vehicle is parked on a flat surface, turn off the engine, and allow it to cool.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Identify the Leak Source

Clean the area around the power steering system components with a degreaser to identify the leak's origin.
Use a flashlight to examine all connections, hoses, and the power steering pump for any visible leaks.

3. Replace Damaged Hoses

Tools Required: Socket set, hose clamp pliers
Remove the hose clamps using the hose clamp pliers.
Disconnect the damaged hose from the power steering pump and steering gear.
Install the new hose by pushing it onto the fittings and securing it with hose clamps, ensuring they are tight.

4. Replace Power Steering Pump (if necessary)

Tools Required: Socket set, torque wrench, power steering fluid
Remove the drive belt from the power steering pump.
Disconnect the power steering lines from the pump (note the orientation).
Remove the mounting bolts and take out the old pump.

Reconnect the power steering lines and reattach the drive belt.

5. Fill Power Steering Fluid

Fill the power steering reservoir with the correct type of power steering fluid as specified in the owner’s manual.
Start the engine and turn the steering wheel from lock to lock several times to bleed any air from the system.

6. Check for Leaks

With the engine running, visually inspect all connections and components for any signs of leaks.
Add fluid as necessary and ensure the level remains within the recommended range.
