System Pressure Test

Fig. 1 Power Steering Pressure Test Connections:

During the following procedure, power steering system pressure may exceed 1200 psi. Ensure proper tool fitment prior to performing test. Exercise extreme caution or damage or personal injury may result.
1. Disconnect high pressure line, install power steering system analyzer 014-00207 or equivalent, using appropriate adapters, Fig. 1. Torque adapters to 12-17 ft. lbs.
2. Install thermometer to power steering fluid reservoir.
3. Ensure analyzer valve is open to allow system to function properly.
4. Do not hold steering wheel against a stop of more the 10 seconds at a time.
5. Start engine, then bleed system by turning steering wheel lock to lock 10 times.
6. Check power steering fluid temperature, if fluid id not 122-140°F, turn steering wheel lock to lock until temperature is reached.
7. The valve on the analyzer must be closed briefly to read operating pressure. Do not leave valve closed for more than 15 seconds.
8. Measure power steering pump output pressure by closing analyzer valve and increasing engine speed to 1000-1500 RPM, 1067 psi should be indicated, if so, proceed to step 9, if pressure is low, replace power steering pump.
9. With analyzer valve open, increase engine speed to 1000-1500 RPM.
10. Turn steering wheel fully to left or right, then read measured pressure, 1067 psi should be indicated, if pressure is low, replace steering gear.
11. Remove analyzer and adapters.
12. Reconnect high pressure line, then torque fitting to 12-17 ft. lbs.
13. Remove thermometer, then bleed system by starting engine and slowly turning steering wheel from lock to lock 10 times.
