Specifications:
| FAQ_Q1 | Why is the pump making a whining noise all of the time? |
| FAA_A1 | A whining pump is usually caused by air in the power steering system. Inspect the reservoir for proper fluid level. If fluid has foam or air bubbles present, air has entered the system or has not been properly bled (ensure all hoses/clamps are tight). Some systems require special vacuum bleeding procedures. |
| FAQ_Q2 | Why do I still have hard steering in one direction after I replaced the pump? |
| FAA_A2 | The problem is most likely in the steering unit-the pump does not know left from right. Check for binding steering components and repair as necessary. |
| FAQ_Q3 | I bought a replacement power steering pump and my original pulley has a loose fit on the replacement pump shaft. What should I do? |
| FAA_A3 | The pulley may have cracked upon removal. If the shaft was mushroomed before removing the pulley, it has now enlarged the bore in the pulley. The pulley must be replaced. |
| FAQ_Q4 | I only have assist when increasing engine rpm after installing the replacement pump. What's causing this? |
| FAA_A4 | There may be debris in the flow control valve bore not allowing the flow control valve to move as it should. (Valve and bore are located behind the high pressure fitting on the pump). The system must be checked for contamination and flushed. |
| FAQ_Q5 | Should I ever change my fluid, even though nothing is wrong? |
| FAA_A5 | Yes. Some O.E. manufacturers recommend that power steering fluid be changed at 50,000 miles and continue at that interval. Just like engine oil, power steering fluid will eventually break down and carry suspended contaminants from component wear and breakdown. Follow your vehicle's O.E. manufacturer's recommendations on fluid change intervals. |
