However, if you're determined to attempt it yourself, here's a general overview. This is not a complete guide, and you should consult a repair manual specific to your 2007 Pontiac G5 for precise instructions and torque specifications. Incorrect procedures can lead to damage.
What you'll need:
* New power steering fluid: Use the type and amount specified in your owner's manual (typically Dexron VI or equivalent).
* Drain pan: To catch the old fluid.
* Wrench: To remove the drain plug from the power steering fluid reservoir.
* Funnel: To add the new fluid.
* Jack and jack stands (or ramps): For easier access to the reservoir.
* Gloves: To protect your hands from the old fluid.
* Shop towels or rags: To clean up spills.
* Power steering fluid reservoir location diagram (from your repair manual): Crucial for locating the reservoir and associated components.
General steps (consult your repair manual for specific locations and procedures):
1. Safety First: Ensure your car is parked on a level surface, the engine is off, and the parking brake is engaged. Wear safety glasses.
2. Locate the Power Steering Fluid Reservoir: Consult your repair manual to find the exact location. It's usually a reservoir with markings indicating the minimum and maximum fluid levels.
3. Drain the Old Fluid: Carefully remove the drain plug (if your model has one; some systems require removing a hose). Let the old fluid drain into your drain pan.
4. Remove and Clean the Reservoir (Optional but Recommended): Some reservoirs can be removed for better cleaning. If you do this, be careful not to damage any attached lines or sensors.
5. Refill the Reservoir: Using a funnel, add the new power steering fluid to the reservoir, checking the level frequently and avoiding overfilling.
6. Bleed the Air (The Most Crucial Step): This is where things get complicated. You need to bleed the air out of the system. Methods vary depending on the vehicle, and your repair manual will provide the most accurate instructions. This often involves turning the steering wheel lock-to-lock while the engine is running (with someone adding more fluid as needed) to purge air bubbles. This step is critical to prevent damage to the power steering pump.
7. Check the Fluid Level: After bleeding the system, check the fluid level and add more if necessary.
8. Test the Power Steering: Start the engine and carefully turn the steering wheel lock-to-lock. Listen for any unusual noises.
9. Dispose of the Old Fluid Properly: Power steering fluid is hazardous waste and should be disposed of according to your local regulations.
Again, this is a simplified overview. Attempting this without a repair manual specific to your 2007 Pontiac G5 is risky. The bleeding process is particularly important and can vary significantly between car models. Improperly bleeding the system can cause serious damage. A mechanic will have the expertise and specialized tools to do this safely and correctly. The cost of repair from a failed attempt will likely far outweigh the cost of professional service.
