A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.

I noticed excessive leaking with the PS hoses/clamps at the reservoir and the hose ends at the cooler hard line. I removed the OE "beverage system" type clamps and replaced them with regualar Fuel Injection line clamps to stop the seeping at the connection points.
