Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the correct type of fluid if low (Porsche CHF 202).
Inspect the fluid for contamination or discoloration.

3. Inspect the Power Steering Pump

Visually check the power steering pump for any signs of leaks.
If leaks are present, replace the pump:
- Remove any obstructing components for access.
- Disconnect the power steering lines and electrical connections.
- Unbolt the pump and replace with a new unit, ensuring proper alignment.

Check the steering rack for any visible damage or play.
If damaged, replace the steering rack:
- Disconnect the battery again.
- Remove the steering linkage connected to the rack.
- Unbolt the steering rack from its mounting and replace it with a new one.
- Reconnect the steering linkage.

5. Inspect the Drive Belt

Locate the drive belt connected to the power steering pump.
Check for any signs of wear or damage (cracking, fraying).
If damaged, replace the belt:
- Loosen the tensioner and remove the old belt.
- Install the new belt, ensuring it is properly routed.
- Re-tighten the tensioner to manufacturer specifications.

6. Reconnect Battery and Test

Reconnect the battery once all repairs are completed.
Start the engine and turn the steering wheel from lock to lock to bleed the system of air.
