Power Steering Pump: Description and Operation
POWER STEERING PUMPThe power steering pump is a CB-series, vane-type positive displacement pump with an integral fluid reservoir. (Pumps used with supercharged engines also have a remote reservoir for checking and adding fluid.) A pressure relief valve limits maximum system pressure, and is located inside the flow control valve in the pump housing; the relief valve is not serviced separately. The power steering pump is driven by the engine via an automatically tensioned drive belt.
MAGNASTEER(TM) POWER STEERING SYSTEM
The Magnasteer(TM) system is a speed-dependent power steering system. The system provides power assist at varying levels depending on need. A bi-directional magnetic rotary actuator in the steering gear adjusts the amount of torque (driver effort) necessary to turn the steering wheel. The EBCM or EBTCM, located at the lower left-hand front of the engine compartment, varies this torque by adjusting the current flow through the actuator. The amount of adjustment will be directly to wheel speed.
