J 44721 (KM-354-B)
Power Steering Analyzer
Test Procedure
Check the fluid pressure as follows to determine whether the trouble is in the
pump or the gear unit.
- Check the power steering fluid level and the power steering pump belt
tension. Refer to
Checking and Adding Power Steering Fluid
.
- Disconnect the high pressure line at the pump. Use a small container to
catch any fluid.
- Connect the hose of the pressure test gage kit J 44721
to the power steering pressure hose from the
power steering pump.
- Place the gear selector lever in PARK, automatic transaxle-equipped vehicles
or NEUTRAL, manual transaxle-equipped vehicles. Set the parking brake.
- Open the gage valve fully.
- Start the engine and let it idle.
- Turn the steering wheel from lock to lock several times to warm the fluid
to operating temperature.
- Increase the engine speed to 1,500 RPM.
Notice: Do not leave the valve fully closed for more than 5 seconds, or the
pump could be damaged internally.
- Close the gage 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).
- Immediately open the gage valve fully.
- 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.
