Test Procedure

Turn the ignition switch to the OFF position. Place a drain pan under the vehicle in order to catch any power steering fluid. Disconnect the power steering pressure pipe from the power steering pump. Install the Power Steering System Analyzer (J- 44721) and the adapters to the power steering pump on the pressure side. Inspect and add ONLY approved power steering fluid as necessary in order to ensure that the power steering fluid is at the proper level and not contaminated. Is the fluid at the proper level and free from contamination? If yes, go to step 3 . If no, go to next step.
Fill or drain and refill the fluid as necessary. Is the fluid at the proper level and free from contamination? If yes, go to next step.

NOTE: DO NOT hold the steering wheel in the full turn position longer than 5 seconds, as damage to the steering pump may result.

Fully open the Power Steering System Analyzer valve. Start the engine. Turn the steering wheel and BRIEFLY hold the steering wheel against the steering stop in order to release any trapped air from the system. Inspect and ensure that all of the power steering pipe/hose connections are not leaking. Observe the pressure reading. Is the pressure reading greater than 230 psi (1379 kPa)? If yes, go to next step. If no, go to step 5 .

CAUTION: A restriction may be present in the power steering system. Turn off the engine IMMEDIATELY.

Locate and repair the restriction. Did you complete the repair? If yes, go to step 13 .
Inspect and add ONLY approved power steering fluid as necessary in order to ensure that the power steering fluid is at the proper level. Allow the engine to run until the engine reaches full operating temperature. Record the pressure reading and flow reading (A). Partially close the Power Steering System Analyzer valve until the system pressure reaches 700 psi (4826 kPa), then record the FLOW reading (B). Subtract flow reading B from flow reading A. Is the flow DECREASE greater than 3.8 L (1 gal) per minute? If yes, go to step 11 . If no, go to next step.
Fully close then open the Power Steering System Analyzer valve 3 times. Record all of the high pressure readings. Are the three high pressure readings within specifications? See POWER STEERING PUMP SPECIFICATIONS . If yes, go to next step. If no, go to step 11 .
Are the three high pressure readings within 345 kPa (50 psi) of each other? If yes, go to next step. If no, go to step 11 .
Increase the engine speed to approximately 1500 RPM. Record the flow reading. Is the actual flow reading within specifications? See POWER STEERING PUMP SPECIFICATIONS . If yes, go to next step. If no, go to step 11 .
Is the difference between the actual flow reading and the maximum flow specification more than 3.8 L (1 gal) per minute? If yes, go to step 11 . If no, go to next step.
Turn the steering wheel from steering stop to steering stop and record the FLOW readings at each stop. Is the flow LOWER than 3.8 L (1 gal) per minute? If yes, go to step 14 . If no, go to step 12 .
Replace the power steering pump. See POWER STEERING PUMP under REMOVAL & INSTALLATION. Did you complete the replacement? If yes, go to step 13 .
The power steering gear is leaking across the piston or bypassing the valve circuit. Replace the power steering gear. See POWER STEERING GEAR under REMOVAL & INSTALLATION. Did you complete the replacement? If yes, go to next step.
Test the power steering system for the original condition. Does the original condition still exist? If yes, go to step 1 .
Disconnect and remove the Power Steering Analyzer from the vehicle. Connect the vehicle power steering pipes/hoses. Bleed the power steering system and add fluid as necessary. See HYDRAULIC SYSTEM BLEEDING under LUBRICATION. Did you complete the repair? If yes, system is okay.
