Power Steering Pump: Testing and Inspection
Preliminary Inspection
Before performing the pump flow and pressure test, complete the following checks for conditions which could cause loss of power assist. Take
corrective action if necessary.
1. Check power steering oil reservoir for proper fluid level.
2. Check tires for correct air pressure.
3. Check drive belt for proper tension.
4. Check power steering pump for correct model and vehicle application.
5. Check for correct size power steering pump pulleys on power steering pump and engine.
6. Check entire system for damage. Replace parts as necessary.
If the above items are correct or have been corrected and the loss of assist still exists, test the power steering pump flow and pressure to determine
whether the trouble is in the power steering pump or hoses.
