Power Steering Pump: Description and Operation
PUMP
DESCRIPTION
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 integral reservoir used on the 3.7L only is attached to the pump body with spring
clips. The 2.4L uses a remote fluid reservoir. The power steering pump is connected to the steering gear by the pressure and return hoses.
OPERATION
The power steering pump is a constant flow rate and displacement, vane-type pump. The pump internal parts operate submerged in fluid. The flow
control orifice is part of the high pressure line fitting. The pressure relief valve inside the flow control valve limits the pump pressure.
NOTE: Power steering pumps have different pressure rates and are not interchangeable with other pumps.
