Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Power Steering Pump
Description
Hydraulic pressure for operation of the power steering gear is provided by a droop-flow type power steering pump. The pump output characteristic is called droop-flow because output decreases with speed. The pump provides assistance consistent with demand. It provides less assistance at highway speeds to enhance directional stability and control, while providing more assistance for steering ease in avoidance and parking maneuvers. The pump also responds to increases in system back pressure (such as when the vehicle negotiates a sharp turn) by raising the pump flow rate.
The belt driven power steering pump (2) is mounted to the front of the engine. The pulley can be serviced separately from the pump if damaged.
