Power Steering Pump - Operation

OPERATION





The power steering pump (4) 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. The reservoir is attached to the pump body with three bolts (7), except if the vehicle is equipped with a 5.7L or Diesel engine then it has a remote reservoir mounted to the fan shroud. The power steering pump is connected to the steering gear by the pressure and return hoses.

NOTE: Power steering pumps have different pressure rates and are not interchangeable with other pumps.
