- Bleed the system using a vacuum pump kit if your car has a bleed valve. Read your vehicle’s manual to see if your power steering has a bleed valve. If it does, purchase a vacuum pump kit for a power steering system and slide the end of the vacuum pump’s hose over the bleed valve.
What is the best procedure for bleeding the air from a power steering system?
Bleeding the power steering system For most power steering-equipped vehicles, this is a simple process. Turning the steering wheel lock to lock several times will remove any unwanted air in there.
How do you vacuum air out of a power steering pump?
Begin by starting the engine and letting it idle. Draw 20-25 inches of vacuum on the pump. As you draw the vacuum, you’ll hear the pump start to make noise as you’re pulling the air from the fluid. While the vacuum stays applied, turn the steering wheel from stop-to-stop 10 times.
How do you get brake fluid out of power steering?
If you have started your car, it has already mixed up and flushing the entire system is recommended. Using a turkey baster or fluid pump, you can simply remove the brake fluid from the reservoir. Another way to remove the fluid is to detach the return line from the steering pump on the primary side.
How do you burp a power steering system?
To bleed the system, raise the wheels off the ground and fill the reservoir with fresh power steering fluid. Start the engine and turn the wheel left and right about 20 times or so, but do not hold it against the stops for more than 5 seconds.
How do you prime a power steering pump?
To prime the pump, hand turn the pulley in the proper direction for your vehicle. Rotation shown is typical for most applications. To prime the pump, hand turn the pulley in the proper direction for your vehicle.
How long does it take to get air out of power steering?
First make sure it’s full. Then start it up, turn the steering wheel all the way left then all the way right, two times slowly. Then shut it off. Wait 10 minutes and repeat, if it seems there still air it should disappear with normal driving.
How do I know if my rack and pinion or power steering pump is bad?
Pump failures generally have symptoms of leaking, noise and loss of steering assist (making steering possible with more effort). Rack and pinion failures are typically leaking,or teeth in the rack (more likely) or teeth in the pinion (less likely). These leaking location is readily determined.
Is it OK to put brake fluid in power steering?
Can brake fluid be used for power steering? The answer is a resounding no. If you used brake fluid in your power steering system, it would cause significant damage.
What happens if you accidentally put power steering fluid in the brake fluid?
The most common mistake is adding power steering fluid to the brakes. Power steering fluid contamination will cause seals to immediately begin swelling. As the seals swell, they move forward and block the passages that allow the brake system to function. One example is the return ports in the brake master-cylinder.
Can we use ATF for power steering fluid?
You can use ATF or automatic transmission fluid in your power steering pump as a substitute for power steering fluid when you’re in a bind. ATF benefits you by having detergents within its formula that help in keeping your system clean. Many cars and trucks actually require ATF in their power steering pump.
Where is the bleed valve on a power steering pump?
Locate the power steering bleed valve on the steering box. If you have difficulty finding it, just follow the high pressure line from the power steering pump to the other end, which will be in the power steering box. Push a hose on the end of the bleeding valve.
How does air get into power steering?
The only areas that air can be sucked in to the system is the front seal of the power steering pump, the low pressure connection on the pump or the pipework between the pump and the reservoir.
If you’ve recently changed any component of your hydraulic power steering system and the power steering has developed air bubbles that are causing a groaning sound, the factory-approved procedure is to use a vacuum tool to bleed the power steering system. Automobile manufacturers no longer recommend that you turn the steering wheel from lock to lock. This can result in pressures of up to 2,000psi, which can cause a hose or seal to explode. Furthermore, it is not as successful at removing the air as it could be.
This Mitivac MITMV8500 kit and Mitivac MVA660 power steering adapter, both of which are featured here, are excellent tools for bleeding all car systems, including the coolant reservoir.
This will exhaust all of the air from the power steering rack, lines, cooler, and pump, among other things.
How to use vacuum to bleed brakes
Then, using the hose that is included in this kit, connect it to the plastic collection cup lid on the hand-held vacuum pump and collecting cup. Then connect a second hose to the bleed screw on the caliper or wheel cylinder. Vacuum the caliper or wheel cylinder with the vacuum pump running and loosening the bleed screw to force the fluid out.

How to Bleed the Power Steering System
Dan Ferrell is a writer who specializes in do-it-yourself auto maintenance and repair. In the field of automation and control technology, he holds credentials. When bleeding the power steering system, make sure to check for leaks if they are present. The photo was provided by schwartz.mark on Flickr. What is the purpose of bleeding the power steering system? Perhaps turning the steering wheel has gotten more difficult, or parallel parking has become more difficult. Air trapped in the power steering system can manifest itself in a number of different ways.
- A whine may be heard coming from the steering pump. It appears that bubbles are forming in the reservoir fluid. The level of reservoir fluid is low and frothy. It’s difficult to turn the steering wheel. There is a leak in the steering system. When turning at low speeds, you may hear a grunt or snarling sound. When the steering wheel is turned completely to the left or right, it makes a groaning sound. When you turn the steering wheel, you hear a buzzing sound. During operation, the steering system emits a clunking sound, which is audible.
Air can enter the system through a variety of routes, including:
- Whether it’s due to a faulty hose, fitting, seal, or component
- A loose connection
- After you’ve replaced a system component
- After you’ve removed and rejoined a hose
- Or any combination thereof
The sections that follow will guide you through the process of checking for trapped air and, if required, bleeding the system. Depending on your particular model, you’ll be able to choose from a number of different approaches. In order to determine the suggested process for your specific model, it is a good idea to consult your car’s owner’s handbook or vehicle maintenance manual. It is possible to obtain a copy of the repair manual from Amazon by purchasing an aftermarket, low-cost copy. Haynes manuals provide numerous maintenance, part replacement, and troubleshooting instructions, as well as illustrations and specifications, to assist you in doing any of these chores at home with ease.

1. Checking the Steering System for Trapped Air
Most likely, you are unsure whether or not air is present in the steering system of your car. Here are a number of basic tests you may do at home to determine whether or not the system is deficient in air. When there is insufficient fluid in the reservoir: Fill the reservoir with fluid until it reaches the Cold Full level. Consult your car’s owner’s handbook or vehicle maintenance manual to determine which type of steering fluid is appropriate for your specific model of vehicle.
- If regular operation is resumed without the occurrence of any sounds or the application of excessive force to the steering wheel, everything is in order. If the fluid level dips again, it indicates that there is a leak in the system that has to be repaired. If the fluid level remains steady but there is still noise or hard steering, go to the next test.

The vehicle is in good working order if regular operation can be resumed without any sounds or hard steering. It’s possible that there’s a leak in the system, which you’ll have to fix if the fluid level dips again. The following test should be performed if the fluid level is steady, but there is still noise or hard steering.
- Warming up the engine to its operational temperature is essential. For example, you may let the engine idle for around 20 minutes before taking it out to the interstate for a 20-minute trip and then coming back
- Returning to the house, start the engine and turn the steering wheel about 15 times, going from one side to the other and from right to left, without striking the brakes or locks. Start by turning off the engine and opening the hood. Examine the fluid level in the reservoir.
- If the fluid seems foamy or has bubbles in it, this indicates that there is air in the system, and you must bleed it. If you are still unsure, you can proceed to bleed the system regardless of your feelings. It will just take a few minutes of your time
If you have opted to bleed the system, make sure you have the car repair handbook for your specific vehicle or that you know which approach is ideal for your application before you begin. Turning the steering wheel from lock to lock is a frequent and straightforward way of bleeding the brakes. Photograph by Shamia Casiano, courtesy of Pexels.
2. General Steering System Bleeding Procedure
The process outlined below is a basic guideline for purging air from the power steering system. In other cases, however, manufacturers supply their own instructions or encourage the use of a vacuum pump for this procedure, particularly in the case of late-model automobiles.
Check out the next section for further information on how to utilize a specific bleeder kit for this purpose. Consult your car’s owner’s manual or vehicle maintenance manual if necessary to complete this task.
- Make sure you park in a secure area on flat ground. Check to see that the engine is completely cold
- Open the hood and check the steering fluid level in the reservoir. If required, top off the steering fluid to get it up to the Full Cold level.
- Use only the steering fluid suggested by the manufacturer of your vehicle. Consult your vehicle’s owner’s handbook or maintenance manual for further information.
Lift the wheels off the ground using a floor jack and secure the car with a set of jack supports to prevent it from rolling away. Start the engine by pressing the start button. For best results, move the steering wheel slowly from left to right and right to left 10 times without hitting the brakes or locks. This will help to avoid seal damage. It is necessary to do this step in order to drive air into and out of the system. Have a second person keep an eye on the fluid level. You must avoid allowing the reservoir to get depleted.
- If more fluid is required, add it.
- Stop the engine and get out of there.
- Additionally, if you have a late-model car, a vacuum pump should be used to bleed the system.

3. Using a Power Steering Bleeder kit
Using a vacuum pump to bleed the system will be necessary if the manual technique does not appear to be effective (e.g., you still observe bubbles in the reservoir fluid after using it). A vacuum pump can also be used to bleed the system if your car is a recent model. Continue on to the next part if you have not already. The manual bleeding mechanism is explained in further detail in the video that follows. It is possible to bleed the steering system with a hand-held vacuum pump, which is especially useful on late-model cars.
- Place your vehicle in a secure location on flat ground. Check to see that the engine is running cool. Open the hood a crack
- Clean the reservoir cap of the steering system using a soft cloth. Taking off the cap
- Instead of using the cap, attach the bleeder kit adapter to the reservoir instead. Connect the hand-held vacuum pump to the bleeder kit adapter using the included connector. Set the parking brake and the gearbox to Park (automatic) or Neutral (manual) to prevent the vehicle from rolling away. Start the vehicle’s engine. Apply a vacuum of 20 inches of mercury
- Wait approximately 5 minutes to verify whether the suction is still effective
- You may notice that the needle on the vacuum gauge begins to decrease somewhat as a result of the air within
- However, if the needle begins to drop excessively, there is most likely a leak in the system that is allowing air to enter the system. If required, consult your vehicle’s owner’s handbook for assistance. If your car has a hydro-boost system, depress the brake pedal twice
- Otherwise, push it once. Without touching the brakes or locks, slowly move the steering wheel from side to side, then from right to left ten times. Rotate the wheels until they are in the middle position. Ensure that the engine is turned off
- Releasing the vacuum will allow you to remove the reservoir’s bleeder kit adapter. If you notice froth or bubbles on the surface of the fluid, wait a few minutes until the bubbles have disappeared. Then, as needed, replenish the fluid in the reservoir.
- Use just the steering fluid that has been approved for your application. Consult your vehicle’s owner’s handbook or maintenance manual for further information.
Install the bleeder kit adapter and connect the hand-held vacuum pump to the adapter to complete the installation. Start the engine by pressing the start button. Apply a vacuum of 20 inches of mercury. If your car is equipped with a hydro-boost system, depress the brake pedal two times to activate the system. Stop the engine and get out of there. Remove the bleeder kit adapter from the reservoir and let the suction out of the system. As needed, replenish the fluid in the reservoir. Remove the reservoir cap and reinstall it.
Other car models, such as Hondas, may necessitate the use of a particular bleeding process specified by the manufacturer.
4. Bleeding a GM or Honda Power Steering System
General Motors suggests following a precise process when bleeding the power steering system. In general, the most significant distinction is that the engine must be turned off while the system is being bled.
This will prevent metal components within the pump from coming into direct touch with the existence of air pockets, which might cause damage to the pump. Follow these procedures to properly bleed the steering system:
- Make sure you park in a secure area. Check to see that the engine is running cool. Make full use of the steering steel wheel by turning it completely to the left (GM) or right (HONDA). Check the level of the power steering fluid by opening the hood. If required, top off the fluid until it reaches the Cold Full level
- Be sure to use the type of fluid that is advised for your particular model. Consult the owner’s manual or a car maintenance manual for assistance. To do this, raise the front wheels and secure the car with a set of jack supports, then choke the back wheels with a jack. Turn the steering wheel slowly and smoothly all the way to the right and left, only touching the stop or lock buttons, for a total of at least 20 times.
- For steering systems with a lengthy return line or a fluid cooler, turn the steering wheel 40 times fully left and right
- For other systems, turn the steering wheel 20 times fully left and right. Have a second person keep an eye on the fluid level. Any spilled fluid that happens during this phase should be wiped up immediately, and the fluid level should remain at Cold Full. As air is removed from the system, the fluid level should decrease somewhat. If the fluid level does not decrease, it is possible that there is an obstruction inside the reservoir or steering pump, maybe caused by an air bubble. The use of a hand-held vacuum and a steering-system bleeder kit may be necessary if just turning the steering wheel left and right does not eliminate the bubble. Take a look at the preceding section. If you notice that the steering fluid has turned milky or tan, or if bubbles emerge in the steering fluid during this phase, stop and look for a loose connection or fitting, a broken seal, or a faulty hose or component that may be allowing air into the system.
On GM Models
- Start and idling the engine are recommended. Refill the reservoir with fluid to bring it up to the appropriate level
- Allow the engine to idle for approximately two minutes while moving the steering wheel to the left and to the right. Then check that the following requirements are met:
- The wheel should turn smoothly when you turn it. If the fluid level is not consistent, there should be no bubbles or froth, and the fluid should not be discolored
- Otherwise, turn off the engine and inspect the hydraulic system for a component that is allowing air into the system. Check for worn or broken seals, as well as loosened clamps that hold hoses to their fittings, in particular. You should not be able to detect any odd noise coming from the steering system
- If you do, you should get the system diagnosed. A pump grumble or whine may be caused by a hose that is in contact with the engine, frame, or body panel, or by a faulty pump.
On Honda Models
- Make the gasoline system inoperable in order to prevent the engine from starting. One method of accomplishing this is to disconnect the fuel pump fuse. Consult your vehicle’s repair manual if any repairs are required.
- Crank the engine for about 5 to 10 seconds while an assistance keeps an eye on the fluid level in the reservoir. If the fluid level in the reservoir declines, this indicates that there is still air trapped in the system, which must be purged. If required, repeat the bruising and bleeding process. if the fluid foams, let at least 10 minutes for air to purge through the reservoir before cranking the engine again
- To prevent damage to the starting motor, always wait at least 5 minutes or more between crankings. In this case, the system has been bled if the fluid level remains constant and no bubbles or froth occur while revving the engine.
Replace the fuse for the fuel pump. Start the engine by pressing the start button. Check to see that the steering fluid is steady and that no bubbles or foam are visible; otherwise, you may have a loose hose, fitting, or a defective seal or component that is enabling air to enter the system. Verify the information in your vehicle’s maintenance manual if required. Remove the reservoir top and turn off the engine. a. Reduce the height of the front wheels to the ground by bringing them in line with the center of the wheels.
Allow the engine to idle for approximately two minutes while you alternately spin the steering wheel left and right to maneuver.
Check the following conditions to make sure they are met:
- The wheel should turn smoothly when you turn it. If the fluid level is not consistent, there should be no bubbles or froth, and the fluid should not be discolored
- Otherwise, turn off the engine and inspect the hydraulic system for a component that is allowing air into the system. Check for worn or broken seals, as well as loosened clamps that hold hoses to their fittings, in particular. You should not be able to detect any unusual steering system sounds. Diagnose the system if this is not the case. A pump grumble or whine may be caused by a hose that is in contact with the engine, frame, or body panel, or by a faulty pump.
Of course, you should always double-check the correct approach for your specific car make and model. Consult your vehicle’s owner’s handbook or maintenance manual for further information. The presence of trapped air in the steering system might impair your ability to regulate the vehicle’s performance. Basher Eyre’s photo (license: cc-by-sa/2.0) is used with permission.
5. After Bleeding the Steering System
Once you have successfully bled the power steering system, you should check to see if there are any additional problems that you are not aware of, as well as to ensure that the problem has been resolved. Perform the following system checks over the course of the next several days:
- Check to see that there are no bubbles or froth in the reservoir fluid. When manipulating the steering wheel, there should be no background noise. A steady power assist should be provided. Check to see that the reservoir fluid is kept at the right level.
It is necessary to check for a loose connection or a leak in the system when the fluid level lowers or bubbles develop. Following the replacement of power steering system components, system bleeding is required to avoid poor vehicle control, costly repairs, and traffic accidents from occurring. The image is in the public domain.
6. Staying Safe on the Road
It is fairly unusual for air to enter the power steering system through the power steering reservoir. However, you want to cleanse and, if required, address any faults that may have contributed to the situation as quickly as possible. The following problems can result from trapped air in the steering system:
- System noise, shaky steering, and damage to system components are all possible consequences.
As a result, bleeding the system will not only remove trapped air from the lines, gearbox, and pump, but it will also prevent costly repairs as well as a potential road accident due to poor vehicle control. As soon as you notice a problem with your steering system, check it out, diagnose it, and, if required, fix it.
