Jack the front of the car off the ground and put on jack stands. Fill the reservoir and WITH THE ENGINE OFF turn the steering wheel all the way both ways and check the reservoir as you do this and add fluid as the air is released. When the air seems to be bled out start the car and turn the steering wheel again all the way in both directions about 10x. When the air is bled and the fluid stabilizes drop the car back down and start it again. Once more turn the steering wheel all the way both directions about 10x while checking the reservoir. If it drops a bit just top it off and go for a spin. Check the reservoir one last time when you get back and make sure it's filled to max. This is the correct and easier way to bleed your power steering system of air.
Holy crap ive been doing while the engine is on and cant get the air to come out and it just bubbles out the the top and ive try like 3 times but next time ill try with it off first thanks
Do I need a vacuum for this like in the vid?
@@Redneck_4wheelers did that help?
@@WaveyDaHuman i still havent done it been pretty lazy during this winter
Do you do each step with the cap off?
Dec 7th 2019. I would like to say thank you. I was having problems bleeding the power steering system on my 98 Ford explorer for the past 3 days and could not find any good information on how to do it properly all I found was a lot of misinformation but I'm glad I found your video because now my exploder is back on the road. Thank you.
Thank you for making that short and to the point, it's appreciated. To many jackasses on TH-cam making 20 minute videos for a 10 minute job.
Very nice. Was having issues properly bleeding the system on an 08 Impala, but got it done today following this vid. Thanks for the help!
I'm a half ass competent mechanic,,I totally missed this on my wifes trailblazer, new pump, no PS at idle, I did this procedure, ass saved!! Thanks, liked and subscribed
Great video, clear and concise. Thanks!
The noises never stop!
I have a 1999 Ford Ranger 4.0 4WD. Now it has 190,000 mi. I am the original owner. For the last 15 years the power steering pump has been whining.
2 shops I went to for a replacement asked me if it worked normal besides the noise. Yes, it does and no leaks that I have ever seen. They both said they wouldn't touch it, because they most likely wouldn't be able to make the noise quit. I bought a "new parts" rebuild from summit racing. Decided not to install myself because I might run into some unknown problems. Had a shop do the install and it was better initially (except near full turning). Within a week it was back to making noise. Not as loud but not quiet like it was 15 years before. I have a hand vac and plug fitting for the reservoir. That helped a little, but kind of changed the points of when the noise starts, or stops. I get a good seal with the fitting and it will hold vacuum overnight. For 2 days now I am driving it with the vacuum set on the pump. 😄 Not fix yet. Any ideas? Somebody must know what the problem is.
I finally did get all the air out of the system. The hand held vacuum pump did nothing in the beginning because there was too much air in the system. I could not pull any vacuum with it even after 15 min of pumping. So here is what I had to do: I have a one man pneumatic brake bleeder that uses air pressure to create a vacuum. I hooked this up to a mighty vac vacuum adapter for ford power steering reservoirs and sucked most of the air out of the system with the motor running by turning the vacuum on and off for about 10 minutes. Then I hooked up the hand held pump and was finally able to pull a vacuum. Red PS fluid was coming up into the fluid separator even at 10 lbs and it was full of tiny bubbles. I kept it at 10 until fluid stopped coming out. Then I went to 15 / 20 /23 doing the same procedure until there were no more bubbles. 23 was the highest I could get it. I stopped the motor and let it cool off for 2 hrs, then repeated with the hand held pump.. There was still a little air in the system, but fluid did not squirt out of the vent hole in the cap anymore when the motor was shut off. I let the owner drive the car for a day like that, then repeated the procedure.
The only way i got mine to stop foaming up and causing a whine was to use about half a quart of dexron III automatic transmission fluid. I tried every brand of power steering fluid i could find. The prrstone Honda fluid worked best but still whined hard after a 40 min drive.
I said screw it and put the trans fluid in it. we used automatic transmission fluid in power steering systems all the time back in the 80s. In fact the owners manual of my olds cutlass said you can. And now mine is whisper quiet.
On my 84 gmc I had the mechanic to just go back and forth with the steering after installing the pump then drove it and added more fluid and went back forth a little bit and it worked
You rock man, so helpful thank you
Good video and easy for understand .. Thanks
I wanted to see the car run with no grinding noise. Did the noise go away and how many times did you repeat your process to bleed all the air and make the noise go away.
Very clear instructions👍 [2019]
Did this and worked awesome those new cars like my 2014 traverse steering the wheel does not work you need to do this awesome thank you
Nice video, thank you Sir.
2004 Pontiac Grand Prix. I have replaced pump and lines. Worked great for about 3 -5days. Did the side to side to release air out of lines and the pump still found away to come out of position. It’s extremely hard to turn unless I keep my adding power steering fluid.
Will this method help me?
Watching this video I finally figured out why my nasty honda is making a whining noise even after replacing the pump I forgot to bleed the line and realized the line is filled with air 😴 thank you so much you have a sub here 💪
And found out there’s a recall for the pump seal . I have to replace that as well
What year of honda?
Moving the steering wheel from left to right while 10 times the front of the vehicle is on jack stands and the engine idling will help. 👌
@@eluniversodelecuador didn't help me...😥 in so flustered!!!
thank you Micheal Scott
The way this guy explains how to do it with a manual pump is %100 percent accurate...Just did it on a Ford taurus....P.S. i only did 2 times and thats it.(Chaching)$....
My 2003 Ford Taurus is doing the same thing!
Please tell me the location of the power steering fluid in my Honda touring 2015 SUV. Thanks for your informative videos!
Do you have a kit to recommend? I have an 05 CRV.
What are all those numbers on the upper plastic firewall cover? great video BTW, i really need to do this to my car.
dntlss, the Ford used for this video is part of our training fleet here in St. Louis. The numbers on the left are the firing order of the engine. The numbers on the right refer to the DIS ignition electrical polarity of the spark plugs.
Where can I get one of those power steering reservoir cap adapters from? I got the vacuum pump but it did not come with that adapter cap. Great video, thank you for sharing.
Oscar Monge you can get anything from the internet.I don't even call or run to stores anymore.any part or tool is usually much cheaper on the internet than at the store.
I made one out of a sink stopper but you have to hold it down so I did the prochedure with engine off as did the BBB industries tutorial showed.
get it online from a scientific supply co. , 8 or 10 bucks.
i can turn steering wheel without car being jacked up . do you have to jack car up?
If you want to replace your pump again, do it like this video. Jack the truck/car off the ground and set it on jack stands. Fill the res to the full mark. With the engine OFF, turn the wheels back and forth until all the air bubbles are gone (adding fluid as needed). Then start the engine (still on jack stands), and repeat. There should be no whining or gurgling sounds. done. Running the pump with a bunch of air in it is beyond stupid. This vac technique can not remove air in the system.
hawkdsl I should have read this comment first! I did what the video said and it broke my power steering pump
Good luck with that on Subaru.
@@idiotgo why.. do u mean Subaru power steering can't replace fluid by return line drain method?
@@DrNemea You can, unless you get some air in the rack. It's a pain to bleed.
@@idiotgo I thought it was a easy thing to bleed out. Since there are alot of you tube videos about bleeding air by turning steering wheel on open fluid reservoir. I never change PS fluid before.
Having issues bleeding my 4th Gen Firebird, hopefully this vacuum pump kit will work with my car.
Where can i buy the vaccume adaptor
I have a 2001 Kia sportage and it makes noise when I turn the steering when park or moving slow but not when driving can someone help me with this
Great detail. Tks
So let me explain what’s going on with my power steering.
The steering is never hard to turn and the reservoir is never low. I have a 2015 Infiniti Q70L that requires an ATF fluid. My power steering pump randomly makes noise at idle. The ATF fluid is clean and is replaced every 50,000 miles. Currently my Infiniti has 156,000 miles. I performed a vacuum test at 20 pounds of mercury and it passed the test for five minutes. Even though it’s been vacuum tested is there anyway an air pocket could be present in the system? Or is my power steering pump simply need to be replaced? Thankfully I can purchase a brand new Hitachi Power steering pump which happens to be the OEM provider for a reasonable price.
Keep in mind I am a rideshare driver that is on the road constantly picking up passengers.
Maybe renting this tool might be possible.
Thanks
does the method you just describe work on the hyundai 2001 sonata. The ps pump reservoir is about the size of a baby's bottle around the neck
This will work on any hydraulic power steering system. The procedure in our Tech Tip is found in factory service procedures from GM, Ford, and many other manufacturers.
I have issue with my Toyota Camry v6 1999.
I put front car on jak both sides and I turn the tyer by my hand left and right more than 8 times and Suddenly the fiuld come out from power steering Reservoir.
Can you please explain what's the problem is??
Does anyone know what's easiest way to get to power steering in 2001 chevy montecarlo Ss
Does anyone have a part number for 2010 Murano reservoir adapter ?
I got a new power steering replaced and now I get like metal grinding but it sound from the rack and pinion but I’veeeee never had that problem before at all.
Where can I buy one of these pumps and stoppers? I haven’t been able to find them at any chain auto part stores.
Is it possible for you to share a link? Thank you in advance.
on amazon "power steering vacuum adapter"
Forget that. You just need a fluid extractor. Mightyvac mva6851.
no special tools huh?
seriously... smh
Seriously everyone have one of those air vacuums in there tool boxes ...fo reals dude !!!!
That's a common tool. 😑
I bought the Mityvac pump Model Mv8000 to remove the air from the power steering of the ute ford falcon year 2000 that I have. Is this pump correct?
Yes, the Mityvac MV 8000 is perfect!
Use the MityVac MVA 662 reservoir adapter for Ford pumps or the universal adapter kit MITMVA 670 for Ford, GM, and most other makes. You can find them online for a reasonable price.
Thanks for the quick response. I used it and it really solved my problem. It took me only 4 days to be delivered and it was worth it.@@GarageGurus
Ya I always carry a vacuum pump in my tool box 🤣
Question.I have 2002 duramax that had a leaking hose from the brake assist to the ps gear box.Everthing was working perfect.brakes and power steering.After shop replaced the hose i now dont have power steering at a idol or low RPM sand brakes dont work so good at low RPM either.They only work good with foot on the throttle or driving down the hyway.Whats wrong??
Probably still has air in the system, Google how to flush/bleed hydro boost power steering. Short version, you want to jack the front end up and very slowly turn the wheels lock to lock, then slowly press the brake pedal and turn lock to lock again. Repeat this step several times.
My car sounds like its got 25 inches of vacuum at all times, but its not hooked up to a vacuum pump! I tried to bleed it with the reservoir cap off and engine running. Turned the wheels and the thing still groans like its got 25 inches on thr vacuum pump in this video. Even worse when revving the idle. Im going to try this vacuum pump method, and see if anything improves. Next step will be to buy a new PS pump. Engine has 68k miles, but its an LS1 that was swapped into an 80s Firebird. The previous owner may have screwed something up. I have a video of me driving by at high speed and all ya hear is the dang PS pump instead if the engine. If this thread is still alive, please help!
does the car need to be raised ?
my power steering rack is leaking oil so I bought a brand new power steering rack on ebay $400 aus. My motor mechanic told me to change the power steering pump to. I brought a new power steering rack do I need a power steering pump or not. I do not want to put one in because there's one sounds ok. just the power steering rack was leaking
It's probably a good idea because you may have contaminants in the pump that will get pushed into your new steering rack. It's more precautionary in my opinion.
my car is having heavy steering. i have changed the fluid but unable to decide how to draw air out. my pump is not making any noise. car model Opel Astra 2001. plz guide

@Mr305Maxxx Nah! I figured out the way by my own.
I made the change for my 2000 honda odyssey but it still the noise
I have a 2002 Merc Sable that has a lot of air in the system. With the engine off, the fluid level is where it should be, but when it is started, the fluid level drops way down and needs about a cup added to bring it back up. As soon as the engine is shut off, the level rises and all the added fluid over flows from all the air pushing it out. Will this method work to get all the air out? I have raised the front end off the ground , and have been turning the wheel from stop to stop with the cap off / engine off for 3 hrs in an attempt to get the air out. Bubbles keep coming up. The most times that I can go from lock to lock and back without any bubbles is 4
It is just difficult to get the air out of Ford power steering systems. Turning the wheels back and forth, raising the front end, ect. give you limited success. The vacuum method outlined in the Tech Tip is recommended by most manufacturers. Buy or borrow a good vacuum pump as shown in the video and buy a power steering bleed adapter. Search: “Power Steering Vacuum Bleed Adapter” They are available from most auto parts stores and an online search will show adapters from $13 to $20 that will work fine. Good Luck!
What you just described is exactly what im facing with ES330. I repaced leaky hoses and no matter a bleed and flush still whines.
I have a 2003 Ford Taurus with the same problem!
Did you find the solution to this. I have the same exact problem on a 2007 ford taurus. I've jacked it up and turned the wheel 50+ times lock to lock. There's still so many bubbles. I didn't have an adapter so the vacuum pump wasn't used. Any help or info?
We have a 2005 Dodge Caravan with a very loud whine coming from the power steering. would this procedure stop the noise?
YUP
I used my Doc Johnson vac pump to suck the air out.
did it work???? I still heard power steering pump noise!
What model and year is the vehicle in above video please??
Ford Taurus but newer year than my 2001 Taurus.
25 " of vac, at H20 or Hg/in. ? Specify units please.
Again, "psi" , - H20 ", Hg/?"? Also, if no change in fluid level after 1st evacuation; indication of no air in system? Correct? No leak. Problem is somewhere else! Check pump output pressure with return securely sealed.
William, the specification is in inches of mercury or In-Hg
What if the vac pump does not pressurize?...is there a leak in the system
If the system will not hold vacuum as described, first verify that the seal between the adapter and the reservoir opening is secure. If vacuum still does not hold, check the inlet or low pressure side of the pump. There may be a loose hose clamp, hardened rubber hose which will not seal, or an “O” ring that is leaking. This will allow additional air to be drawn into the system. Refer to the link below where Garage Guru Mark Isaac talks air leak detection techniques.

I thought you were suposed to check power steering fluid while the vehicle is running?
Hi I have a mercedes R350 power steering gets stif when warm, this happen after replacing power steering reservoir, I can't locate the bleed valve, how I can bleed air from power steering on R350 thanks

Honda is terrible for this problem.
I followed this video to a T because after replacing my pump it would whine even after turning the wheel back and fourth 10 times. It would be fine for about a day then start that loud whine again. I tried several brands of fluid. In order from worst to best. Autozone first, lucas second, then prestone. So i was getting very frustrated with the noise because this pump isnt cheap and i didnt want to ruin it. So went old school and decided to use a trick from the old days. i sucked out some of the fluid in the reservoir until it was below the top hose and added dexron III automatic transmission fluid to the reservoir. Started up the engine and the sound went away in 2 seconds and has been whisper quiet ever since. This is going on 2 weeks and the pump has never whined since.
Welcome
Follow the factory service manual for your specific car
What if I drive for a few days without the cap?
Why check for leaks after? The vacuum from the pump would not hold if there was a leak.
Many times seals and “O” rings can hold under vacuum but leak under pressure and vice-versa. We have seen this in A/C, evaporative purge, and power steering systems. Doing a careful visual check as a final step is always wise.
He's not checking for a leak, he is checking for a fluid drop, because the air in the lines occupy space, when you suck out the air via the vacuum method, the fluid fills in those spaces where the air bubble used to be, resulting in a drop in the fluid volume.
Man this is giving me a headache. I recently installed a new power steering pump on my 04 Legacy. Turning is better initially, but the more sharp turns I make, the more the steering wheel gets stiffer. I popped the hood and realized there's a pool of steering fluid that's leaking from the top of the new steering pump, right where the lines go in. Does anyone have any ideas of what I could try next?
Replace the o-ring in that line, and bleed the pump again.
@@zanes9898 I did end up replacing the o ring and that fixed the leak, however tight turns such as parking, the steering wheel is still hard to turn. I've bled it a few times and it doesn't seem to fix it.
@@clarkgriswold4057 and the fluid isn’t leaking anymore?
I changed my pump amd now when i turn off my car the power steering fluod starts to spill out of the lid. No foam just overflow
Rick S you probably have air in the system. Check for cracks in the hoses or the cap. It could be drawing air. If every thing looks good have a mechanic check it. They have all the right tools.
Changes a whole pump by himself
>Just take it to a mechanic
Do you know the name of your wife's boyfriend?
You check the level with engine running? Some systems if you top off with engine off will overflow after normal operating temp is reached when shut off.
kittylovermybut HAHAHAHA IM DEAD
@@arthursmith643 Also check the fine mesh screen in the remote mounted reservoir, as they get dirty and won't return the fluid quick enough to the pump and cause spill over, then vacuum pump out the air out of the system.
will restriction from power steering lines burst a rack
No. The only way pressure can build up in the rack due to a restricted line would be due to the return line, which cannot handle over 100psi, well below the limit that could cause a rack to “burst” which is an event that just does not happen. Besides, power steering pumps have an internal pressure relief valve so that pressure cannot exceed safe limits.
Don't turn on engine. You can cycle the steering back and forth to push the air to the reservoir.if the front wheels are off the ground. You don't even need that vacuum pump. Keeping engine off prevents the pump from engaging so it won't spit out fluid. Simply rotate the wheels by cycling bank and forth on the steering wheel. check reservoir every few cycles for air bubbles. If need be add more fluid but only to proper levels. Do no over fill.
Do you leave the reservior cap off or on during this process?
@@andrue17 Yes
Is the cap on during the process?
Or do you keep the cap off?
Doesn't anybody believe in using fender covers on every vehicle they work on all of the time?
Using a vacuum on a Subaru did not work. It would never draw fluid from the reservoir. You need to start the engine and just turn the wheel.
I don't think I would run the engine while using a vacuum. the pump is creating pressure when running. But I'm no mechanic. I'll try it with the engine off.
do the car have to be jacked up to bleed this way?
Meanwhile the pump is still screaming. Useless...
i though the same thing! at the end of video, the guy says its all set, yet its Still whining...wtf?
@@skip741x3 Normally if you're having these many issues removing air from the system. You likely have a bad pump.
It sounded better before applying vacuum. Still sounded bad at the end of the video. Not sure how this is an improvement.

Yeah your not supposed to vaccum bleed with the engineon gm tech service bulletins for bleeding air always say with engine off. When engine is running it aeriates the fluid and also don't pull anything over 20 in hg with vaccum pump it can blows the internal seals out-of the power steering pump....
my car is Kia forte 2010 the steering is hard to right and easy to left why?
it was still making noise !
Indeed! I was watching as i hoped to see it was solved !!!! ;-(
Who In the hell already has one in their toolbox? WTF
thought that was a SUPRA
Where do I get one of those from
The vacuum bleeding kit made by Mityvac is available from from most auto parts stores and tool suppliers for minimal cost.
Lol just let it run with the cap off for 10 minutes
Really!? I'll try that for sure 👍. Appreciate it.
Abdulai Bah did it work?
@@Youngbaked551 Yep! Pretty sure it worked because. Did the 10 minutes idle with top off on two occasions and it seems to help. No whining noise. Thanks!
Thumb down bc I don’t have any of those tools lol
This is bull he didn’t even show if this worked at the end.
Turns out, all he had to do was change the lower pressure o-ring for $3 total.
Details??
@@mbell5950 Power steering pumps rarely go bad. This issues that usually come up are leaks form the o-rings (which is a $5 fix and 15minutes of work) or the gasket.
Running the engine with air in the power steering system and trying to bleed the system with the engine running is only damaging the power steering pump. The very thing you are wanting to avoid you're doing. What the heck??
Terrible vid. No one has those tools
That fancy penis pump does not work. Previous mechanic replaced absolutely everything for the power steering system while charging the customer way more than the car is worth. I have gone through it all looking for air and fluid leaks and it looks like he did an excellent job. I've been a mechanic for 35 years. I know the Ford Taurus is notorious for power steering problems. I swear I am going to have the biggest pecker by the time I get this one fixed
Yeah right
