2. Identify and Repair the Leak

Check Fluid Reservoir

Remove the power steering fluid reservoir cap.
Inspect for cracks or signs of damage.
If damaged, replace the reservoir.

Inspect and Replace Hoses

Trace the power steering hoses from the reservoir to the pump and rack.
Look for cracks, leaks, or loose clamps.
If damaged, remove the hose:
1. Use pliers to loosen the clamps.
2. Slide the hose off the fittings.
3. Install the new hose and secure with clamps.

Examine Power Steering Pump

Locate the power steering pump.
Check for fluid around the pump.
If leaking, replace the pump:
1. Disconnect the hoses from the pump.
2. Remove mounting bolts using a socket set.
3. Replace with a new pump and reattach hoses.

Inspect Steering Gear

Look at the steering gear for fluid accumulation.
If leaking, you may need to replace the steering gear:
1. Disconnect the steering linkage.
2. Remove mounting bolts and detach the gear.
3. Install a new steering gear and reconnect all components.

3. Refill and Bleed System

Refill the power steering fluid reservoir with the recommended fluid type.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid level again and top off if necessary.
