Section 2 (Power Steering System): Pump: Description
WARNING: This page is about a different car, the 2002 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.
Hydraulic pressure for the power steering system is provided by a belt driven power steering pump. The pump shaft has a pressed-on high strength plastic drive pulley that is belt driven by the crankshaft pulley. The reservoir is attached to the pump body with spring clips on the 4.0L engine. A remote pump reservoir is used on the 2.5L engine mounted to the fan shroud. The power steering pump is connected to the steering gear by the pressure and return hoses.
