Power Steering Flush in Santa Clara

Power steering enables easier turning operation in recirculating-ball steering systems. One system attributes about 80% of the steering force to the hydraulic power assist and only 20% to the driver. This is accomplished through a variety of pumps and valves. If contaminants develop and build up in the system, proper operation of components such as the rotary valve, spool valve, inner and outer valves in the torsion bar, and the pressure relief valve can be affected.

The rotary­ vane pump is the component containing the reservoir for the power steering fluid. The engine’s belt drives the pump, which pulls fluid from the return line at low pressure and forces it into a high­ pressure line. The high-pressure outlet hose is connected to the spool­ valve assembly.

Spool Valve Assembly

The spool­ valve assembly controls the direction of the hydraulic power assist, whether it assists a left or right-hand turn. When the tires are oriented straight ahead, both hydraulic lines contain the same amount of pressure to the steering gear. But high­ pressure fluid is applied in one of the lines as soon as the spool valve is turned one way or the other by the steering wheel. This high­ pressure assist provides the 80% of turning force we previously mentioned.

This Results In:

  • Removal of built-up moisture and contaminated fluid from the power steering system
  • Reduces the risk of leaks and chatter
  • Improves the performance of your power steering
