Maintaining your vehicle’s power steering system is essential for ensuring a smooth and responsive driving experience. Over time, power steering fluid collects contaminants and loses its effectiveness, leading to steering problems and premature component failure. A power steering flush is a cost-effective and straightforward procedure that removes the old fluid and replaces it with fresh, clean fluid, restoring your steering system’s optimal performance.
Before embarking on a power steering flush, it’s important to gather the necessary materials and safety gear. You will need fresh power steering fluid, a funnel, a fluid extractor or turkey baster, a pair of gloves, and safety glasses. Additionally, consult your vehicle’s owner’s manual for specific instructions and precautions related to your make and model.
To begin the power steering flush, safely lift your vehicle using a jack and jack stands. Locate the power steering reservoir, typically a translucent plastic container with a dipstick attached. Using a fluid extractor or turkey baster, carefully extract the old fluid from the reservoir and dispose of it properly. Refill the reservoir with fresh power steering fluid to the recommended level indicated on the dipstick. Repeat this process several times, turning the steering wheel back and forth each time, until the fluid runs clear and free of contaminants. Finally, top off the reservoir with fresh fluid and check the fluid level after a few days of driving to ensure there are no leaks.
Identifying Signs of a Needed Flush
### Noisy Power Steering
A worn power steering system can produce various noises, notably when turning the steering wheel. Such noises may include whining, squealing, or humming. These sounds usually indicate low power steering fluid, which can damage the pump if not addressed promptly.
### Stiff Steering
Another common symptom is stiff steering, especially noticeable during parking or maneuvering at low speeds. This stiffness arises from a lack of lubrication, often caused by degraded or depleted power steering fluid. As a result, the steering components experience increased friction, leading to difficulty in turning the wheel.
### Leaking Power Steering Fluid
Visible leaks of power steering fluid, often accompanied by a burning smell, signify a potential problem. These leaks can originate from various points within the system, including hoses, seals, or the pump itself. Promptly addressing any fluid leaks is crucial to prevent further damage and potential hazards, such as slippery surfaces under the vehicle.
### Fluid Contamination
Contamination of the power steering fluid can compromise its performance and accelerate system wear. Signs of contamination include a murky or dark appearance, a rancid smell, or the presence of metal shavings or particles within the fluid. Contaminated fluid can clog components, reduce lubrication, and lead to premature failure of the power steering system.

Gathering Necessary Materials and Tools
Before you embark on your power steering flush, ensure you have assembled the following essential materials and tools:
Tools:
- Fluid extractor pump or large turkey baster
- Wrench or socket set
- Funnel
- Jack and jack stands (optional, but recommended for access)
- Pliers
- Clean rags or paper towels
Materials:
- Power steering fluid: Refer to your vehicle’s owner’s manual for the recommended type and quantity.
- Power steering system cleaner (optional, but recommended for thorough cleaning)
- New power steering filter (if applicable and recommended for your vehicle)
- Disposable gloves
| Item | Quantity |
|---|---|
| Power Steering Fluid | 2-3 quarts (2-2.8 liters) |
| Power Steering System Cleaner | 1 bottle (optional) |
| Power Steering Filter (if applicable) | 1 |
| Disposable Gloves | 2 pairs |
Draining the Old Fluid
Now that you have the tools and materials you need, you’re ready to start draining the old fluid. Follow these steps:
-
Locate the power steering reservoir. It is usually a small, plastic tank with a black or red cap. The cap may have a power steering symbol on it.
-
Remove the cap from the reservoir. Be careful not to spill any of the fluid.
-
Insert the suction hose into the reservoir. The hose should be about 1/4 inch in diameter and long enough to reach the bottom of the reservoir.
-
Attach the suction hose to the vacuum cleaner. Make sure the connection is secure.
-
Turn on the vacuum cleaner. The old fluid will start to be sucked out of the reservoir.
-
Continue to vacuum the fluid until the reservoir is empty. This may take a few minutes.
-
Once the reservoir is empty, turn off the vacuum cleaner.
| Tips |
|---|
|
If you don’t have a suction hose, you can use a turkey baster to remove the old fluid. Insert the turkey baster into the reservoir and squeeze the bulb to draw out the fluid. |
|
Be careful not to get any of the old fluid on your skin. The fluid is toxic and can cause irritation. |
|
If you spill any of the old fluid, clean it up immediately with a damp cloth. |
Flushing the System
1. Gather Materials:
Before beginning, gather the following materials: power steering fluid (compatible with your vehicle), a turkey baster or fluid extractor, a funnel, a bucket or drain pan, and gloves.
2. Locate Reservoir:
Locate the power steering fluid reservoir, typically found under the hood. It is usually labeled “POWER STEERING” or has a power steering symbol on it.
3. Extract Old Fluid:
Use a turkey baster or a fluid extractor to remove the old fluid from the reservoir. Insert the device into the reservoir and squeeze or pump to extract the fluid. Dispose of the old fluid properly.
4. Refill with New Fluid:
Once the old fluid is removed, use a funnel to pour new power steering fluid into the reservoir. Refer to your vehicle’s owner’s manual for the recommended type and amount of fluid needed.
5. Cycle the System:
6. Repeat Extraction and Refill Process:
Repeat the extraction and refill process 2-3 times to completely flush the old fluid out of the system. This ensures that the new fluid is fully distributed and any contaminants are removed.
Bleeding the System
Once the new fluid is in place, it’s time to bleed the system to remove any air bubbles. This process can vary depending on the specific vehicle, so it’s important to consult your owner’s manual or a qualified mechanic for detailed instructions. However, here are the general steps involved:
1. Start the engine and let it idle
2. Turn the steering wheel from lock to lock several times
3. Repeat steps 1 and 2 until no more air bubbles appear in the reservoir
4. Check the fluid level and add more if necessary
5. Drive the vehicle for a short distance to circulate the new fluid
6. Recheck the fluid level and top off as needed
Be sure to follow the proper safety precautions when performing a power steering flush, as improper handling of the fluid can be hazardous. Some important safety tips to keep in mind include:
| Safety Tips |
|---|
| – Wear gloves and safety glasses when handling the fluid |
| – Do not ingest or inhale the fluid |
| – Keep the fluid away from children and pets |
| – Dispose of the old fluid properly |
By following these steps carefully, you can successfully perform a power steering flush and restore proper operation to your vehicle’s steering system.
