Relief Pressure Test

  1. Close gauge shutoff valve completely 3 times. Record highest pressure attained each time.
  2. If recorded pressures are within specifications and range of readings are within 50 psi (3.5 kg/cm2 ), pump is working properly. See POWER STEERING PUMP PRESSURE TEST SPECIFICATIONS  table. If recorded pressures are above specification and are not within 50 psi (3 kg/cm2 ) of each other, replace pump. If pressures are within 50 psi (3 kg/cm2 ) of each other, but below specifications, replace pump. See POWER STEERING PUMP R & I.
  3. Open gauge shutoff valve. Turn steering wheel from stop to stop, recording highest pressures at each extreme position. Replace steering gear if pressures at each stop are not the same, there is an internal leak within steering gear.
  4. Shut off engine and remove test gauge. Ensure "O" ring at end of high pressure fitting (if equipped) is replaced before connecting fitting to power steering pump. Connect pressure hoses and make any needed repairs.
