Disconnect the battery to ensure safety during repairs.
Secure the vehicle on a level surface and raise it using jack stands if needed.

2. Locate the Leak

Tools Required: UV light (if using dye), flashlight.
Use a flashlight to visually inspect the power steering components for leaks.
If UV dye is added, inspect under UV light to pinpoint the leak source.

3. Replace Damaged Hoses

Tools Required: Socket set, wrench set, fluid catch pan.
Remove the damaged or leaking power steering hose:
- Loosen the clamps using a wrench.
- Disconnect the hose from the power steering pump and steering rack.
- Allow any remaining fluid to drain into the catch pan.
Install the new hose:
- Connect the new hose to the power steering pump and steering rack.
- Tighten the clamps to the manufacturer's specifications (usually around 18-22 inch-lbs).

4. Repair or Replace the Power Steering Pump

Tools Required: Socket set, torque wrench, power steering fluid.
If the pump is leaking:
- Disconnect the hoses from the pump.
- Unbolt the pump from its mounting bracket.
- Replace with a new pump and tighten bolts to the manufacturer’s torque specifications (usually around 25-30 ft-lbs).
Reconnect hoses and ensure no cross-threading occurs.

5. Refill Power Steering Fluid

Tools Required: Funnel, power steering fluid (OEM recommended type).
Fill the power steering reservoir with the appropriate fluid until it reaches the correct level.
Start the engine and turn the steering wheel from lock to lock to purge any air from the system.
