Test Procedure

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2008 Suzuki Reno, 2008 Suzuki Forenza, 2007 Suzuki Reno, 2007 Suzuki Forenza, and 2006 Suzuki Reno. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check the power steering fluid level and the power steering pump belt tension. Refer to Checking and Adding Fluid  and Serpentine Accessory Drive Belt Removal and Installation .
  2. Disconnect the high pressure line at the pump. Use a small container to catch any fluid.
  3. Connect the hose of the pressure test gauge kit KM-354-B to the power steering pressure hose from the power steering pump.
  4. Place the gear selector lever in PARK (automatic transaxle-equipped vehicles) or NEUTRAL (manual transaxle-equipped vehicles). Set the parking brake.
  5. Open the gauge valve fully.
  6. Start the engine and let it idle.
  7. Turn the steering wheel from lock to lock several times to warm the fluid to operating temperature.
  8. Increase the engine speed to 1,500 rpm.
  9. Close the gauge valve fully, and read the pressure. The pump pressure with the valve closed should be between 8,330 - 8,820 kPa (1,208 - 1,279 psi). With electronic variable orifice, the pressure should be between 8,500 - 8,960 kPa (1,233 - 1,299 psi).
  10. Immediately open the gauge valve fully.
  11. Turn the steering wheel all the way to the left and the right. If the pressure is within the specified limits, the problem is not in the pump. Check the power steering gear for leaks.
