Power Steering Fluid Leak Test

2009 Ford Ranger 2D Pickup, 2.3 D, AutomaticSECTION Power Steering Fluid Leak Test
NOTE: This test should only be carried out if a leak in the system has not been detected during a thorough visual inspection. Refer to INSPECTION AND VERIFICATIONΒ .
  1. Remove the power steering pump reservoir cap and check the power steering fluid level. If necessary, add the specified power steering fluid.
  2. Tightly install the Power Steering Evacuation Cap onto the reservoir and connect the Vacuum Pump Kit to the Evacuation Cap.
  3. Using the Vacuum Pump Kit, apply 68-85 kPa (20-25 in-Hg) of vacuum to the power steering system.
  4. Observe the vacuum gauge for 30 seconds. If the vacuum gauge reading drops more than 3 kPa (0.88 in-Hg), a leak is present.
  5. Remove the Vacuum Pump Kit.
  6. Start the engine and insert the Dial Thermometer into the Evacuation Cap.
  7. NOTE: Do not hold the steering wheel at the stops for an extended amount of time. Damage to the power steering pump may occur.
  8. With the engine at idle, raise the power steering fluid temperature to 74-80Β°C (165-176Β°F) by rotating the steering wheel fully to the left and right several times.
  9. Stop the engine and visually inspect the system for leaks.
    • If a leak is evident, repair as necessary.
    • If a leak is not evident, add the specified UV fluorescent tracer dye to the power steering fluid. Use 14.78 ml (1/2 oz) of dye solution for every 1.89L (2 qt) of power steering fluid.
  10. Start the engine.
  11. NOTE: Do not hold the steering wheel at the stops for an extended amount of time. Damage to the power steering pump may occur.
  12. With the engine at idle, raise the power steering fluid temperature to 74-80Β°C (165-176Β°F) by rotating the steering wheel fully to the left and right several times.
  13. Stop the engine and inspect the system for traces of UV dye using the 100W/12 Volt DC UV Lamp. Repair as necessary.
