Here's a general procedure:
1. Locate the power steering fluid reservoir: This is usually a plastic reservoir with markings indicating the minimum and maximum fill lines. It's often located near the engine, but its exact position can vary slightly depending on the engine configuration. Consult your owner's manual for a diagram or check online resources with pictures of the 2002 Impala engine bay.
2. Check the fluid level: With the engine OFF, carefully examine the fluid level in the reservoir. The level should be between the minimum and maximum markings.
3. Add fluid (if needed): If the fluid level is low, slowly add the correct type of power steering fluid. Use a funnel to avoid spills. Add only small amounts at a time, checking the level frequently to avoid overfilling. Overfilling can be just as damaging as underfilling.
4. Start the engine: Once you've added fluid, start the engine and turn the steering wheel slowly from lock to lock a few times. This circulates the fluid.
5. Check the fluid level again: Turn off the engine and let it sit for a few minutes. Then, check the fluid level again and add more fluid if necessary, ensuring it stays within the minimum and maximum marks.
6. Inspect for leaks: After adding fluid, inspect the area around the power steering pump and hoses for any leaks. Look for wet spots or drips.
Important Considerations:
* Low fluid levels can indicate a leak: If you frequently need to add power steering fluid, there may be a leak somewhere in the system. This requires professional repair.
* Dirty fluid: If the fluid is dark, discolored, or smells burnt, it needs to be flushed and replaced. This is best done by a qualified mechanic.
* Type of fluid: Using the incorrect fluid can damage the power steering system. Absolutely verify the recommended fluid type in your owner's manual.
* Safety first: Always work on a cool engine. Be cautious near hot engine components.
If you are uncomfortable performing this task yourself, take your vehicle to a qualified mechanic. They can properly diagnose any underlying problems and ensure the system is functioning correctly.
