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 .

4. Connect the vehicle's power steering pressure hose (2) to Adapter Fitting (special tool #6826, Adapter, LH P/S Tester) (5) (on Hose (special tool #6959, Assembly, Hose) (1) leading to Analyzer outlet). Tighten the tube nut. Refer to SPECIFICATIONS .
5. Connect Adapter Fitting (special tool #6844, Adapter, Power Steering (Truck)) (4) (on Hose (special tool #6713, Hose, Power Steering) (3) leading to Analyzer inlet), to the open power steering pump pressure fitting (6). Tighten the tube nut. Refer to SPECIFICATIONS .
6. Route the hoses away from the exhaust system as well as possible.
