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 Verification. Inspection and Verification

1. Check the power steering fluid level. If necessary, add the specified power steering fluid.

2. Remove the power steering fluid reservoir cap and tightly install the Power Steering Evacuation Cap to the power steering fluid reservoir.

3. Install the Vacuum Pump Kit to the Power Steering Evacuation Cap.

4. Using the Vacuum Pump Kit, apply 68-85 kPa (20-25 in-Hg) of vacuum to the power steering system.

5. 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.

6. Remove the Vacuum Pump Kit.

7. Place a Dial Thermometer in the power steering fluid reservoir.

8. NOTICE: Do not hold the steering wheel at the stops for an extended amount of time. Damage to the power steering pump may occur.

Start the engine. With the engine at idle, raise the power steering fluid temperature to 74-80°C (165-176°F) by rotating the steering wheel fully to the left and right several times.

9. 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. NOTICE: Do not hold the steering wheel at the stops for an extended amount of time. Damage to the power steering pump may occur.

Start the engine. With the engine at idle, raise the power steering fluid temperature to 74-80°C (165-176°F) by rotating the steering wheel fully to the left and right several times.

11. Using the 100W/12 Volt DC UV Lamp, inspect the system for traces of UV dye. Repair as necessary.
