Steering Pump Pressure

  1. Install Pressure Gauge (J-29877-A) with shut-off valve between steering gear and power steering pump. Connect gauge hose furthest from shut-off valve to back of power steering pump.
  2. Fill fluid reservoir. Bleed air from system. Open shut-off valve. Start engine and run to normal operating temperature. Set idle speed to 1500 RPM.
  3. Measure fluid pressure with steering wheel straight ahead. Close pressure gauge shut-off valve for less than 10 seconds. Read pressure and open valve. Repeat twice more. Record highest pressure.
  4. Normal pressure should be 896-1095 psi (63-77 kg/cm2 ). Lower pressures suggest a defective pressure relief valve or pump. Higher pressure indicates a faulty pressure relief valve.
  5. Open gauge shut-off valve. When steering wheel is turned to lock in both directions, pressure should be 780-980 psi (55-69 kg/cm2 ). If pressure is higher than specified, relief valve in power steering pump is defective. If pressure is lower than normal, steering gear may be leaking internally.
