Hydraulic Flow And Pressure Test: Notes

The following procedure is to be used to test the operation of the power steering system on this vehicle. This test will provide the flow rate (Gallons Per Minute (GPM)) of the power steering pump along with the maximum relief pressure. Perform this test any time a power steering system problem is present. This test will help determine if the power steering pump or power steering gear is not functioning properly. The test is performed using tools in the Power Steering Analyzer Kit (special tool #6815, Kit, Power Steering) with appropriate hoses and adapters.

Refer to SPECIAL TOOLS .

1. Check the power steering belt to ensure it is in good condition and adjusted properly.
2. Assemble the following hoses and adapters on the Flow Meter And Gauge (special tool #6800, Analyzer, Power Steering) (3):
   1. Gauge end (inlet) - Hose (special tool #6905, Assembly, Hose) (6) (in (special tool #6893A, Kit, Power Steering) kit), Hose (special tool #6713, Hose, Power Steering) (4) (in (special tool #6815, Kit, Power Steering) kit), Adapter Tube (special tool #6844, Adapter, Power Steering (Truck)) (5) (in (special tool #6893A, Kit, Power Steering) kit)
   2. Valve end (outlet) - Hose (special tool #6959, Assembly, Hose) (1), Adapter Fitting (special tool #6826, Adapter, LH P/S Tester) (2)

3. Unthread the tube nut and disconnect the power steering pressure hose (2) at the power steering pump (1) pressure fitting.
4. Connect the vehicle's power steering pressure hose to Adapter Fitting (special tool #6826, Adapter, LH P/S Tester) (on Hose (special tool #6959, Assembly, Hose) leading to Analyzer outlet). Tighten the tube nut.
5. Connect Adapter Fitting (special tool #6844, Adapter, Power Steering (Truck)) (on Hose (special tool #6713, Hose, Power Steering) leading to Analyzer inlet), to the open power steering pump pressure fitting (6). Tighten the tube nut.
