Tools Required
J 44721
(KM-354-B) Power Steering Analyzer
Check the fluid pressure as follows to determine whether the trouble is in the pump or the gear unit.
Test Procedure
- 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
J 44721
(KM-354-B) to the power steering pressure hose from the power steering pump.
- Apply the park brake.
- Place the gear selector lever in PARK if the vehicle is equipped with the automatic transaxle or NEUTRAL if the vehicle is equipped with the manual transaxle.
- 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.
Specification
The pump pressure with the valve closed should be about 8,500 kPa (1,233 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.
