This FLOW AND PRESSURE TEST (1) Check the power steering belt to ensure it is in good condition and adjusted properly. (2) Connect pressure gauge hose from the Power Steering Analyzer to Tube 6844. (3) Connect Adapter 6826 to Power Steering Ana- lyzer test valve end. (4) Disconnect the high pressure hose from the power steering pump. (5) Connect the tube to the pump hose fitting. steering gear to the adapter. (7) Open the test valve completely. late power steering fluid through flow/pressure test (9) Check fluid level, add fluid as necessary. Start engine again and let idle. (10) Gauge should read below 862 kPa (125 psi), if above, inspect the hoses for restrictions and repair as (11) Increase the engine speed to 1500 RPM and read the flow meter. If the flow rate (GPM) is below Fig. 3 Analyzer With Tube and Adapter For 5.2L & 5.9L 1 – GAUGE HOSE 19 - 4 STEERING DN DIAGNOSIS AND TESTING (Continued) |
