• Fluid leaks: Visible drips or puddles of power steering fluid under the vehicle
• Loss of power steering assist: Intermittent or complete failure of the power steering system
• Stiff or erratic steering: Difficulty in maintaining a steady course or making precise turns

Diagnosing the Problem

Before attempting repairs, it’s essential to pinpoint the root cause of the issue. Follow these steps to diagnose a faulty power steering pump:

1. Check Fluid Level and Condition

• Inspect fluid level: Ensure the power steering fluid reservoir is at the correct level, as indicated by the dipstick.
• Examine fluid color: Fresh fluid should be clear or slightly amber. Dark, cloudy, or burnt fluid indicates contamination or overheating.

2. Test Steering Pump Pressure

• Use a pressure gauge: Connect a pressure gauge to the power steering pump’s outlet port.
• Start engine and turn steering: The gauge should read between 800-1200 psi at idle and increase with engine speed.

3. Inspect Drive Belt

• Check tension: Ensure the drive belt that powers the pump is properly tensioned.
• Look for wear or damage: Replace a worn or damaged belt to prevent slippage and ensure pump operation.
