Pressure Testing

  1. Increase engine speed to 1000 RPM, turn steering wheel to left or right stop position and read pressure. Pressure reading in stop position should be 1109-1194 psi. (7649-8238 kPa).
  2. If pressure is below standard specification, slowly close shutoff valve on power steering analyzer and check pressure. If fluid pressure is okay, go to next step. If fluid pressure is below specification, repair or replace power steering pump.
  3. If fluid pressure meets standard pressure specification, the steering gear is faulty, replace rack and pinion unit. If fluid pressure exceeds standard pressure specification, replace power steering flow control valve.
  4. Turn engine off. Remove power steering analyzer and reconnect all fittings. Fill and bleed hydraulic system. Tighten bolts to specification. See TORQUE SPECIFICATIONS  .
