2. Identify and Replace Leaking Component

Power Steering Reservoir:
- Remove the reservoir cap and drain any remaining fluid into a catch basin.
- Unbolt the reservoir from its mount and disconnect the hoses.
- Replace with a new reservoir if damaged.
Hoses:
- Inspect the hoses for leaks; if damaged, use pliers to loosen hose clamps and remove the old hoses.
- Install new hoses and secure them with clamps, ensuring a tight fit.
Power Steering Pump:
- If the pump is leaking, unbolt it from its mounting and disconnect the supply and return lines.
- Replace with a new power steering pump if necessary.
- Ensure the new pump is properly aligned and tightened to manufacturer specifications.
Steering Rack:
- If the rack is found to be leaking, unbolt it from the chassis and disconnect it from the steering column.
- Replace the steering rack if necessary, following the manufacturer’s installation procedures.

3. Refill and Bleed Power Steering System

Fill the power steering reservoir with the recommended fluid type until it reaches the full mark.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check for leaks during this process and top off fluid as necessary.
