- This video shows how you can change your power steering fluid (oil) and filter on Mercedes R129, R107, W124, W126, W140, W201 and W202. It's a simple DIY job.
The car shown is a 1992 Mercedes 300SL. Video instructions also apply to 1990 to 1993 300SL, 1990 to 1993 500SL, SL320 and a number of R107s, W124s, W126s, W140s and W202s.
The step-by-step process is a common DIY power steering fluid change and very successful at removing most of your old fluid. There are other more complicated methods, but those come with more risks for the DIYer with only marginal benefits.
Parts used in video:
Filter: Hengst E26H (Made in Germany) [or Mann H85]
Fluid: Febi Belstein Power Steering Oil (Made in Germany). 3x1.0L (or 3x 1.1 Quart) bottles.

After watching your Merceds Benz Maintemance video, I must give it an absolute AAAA! Excellent training film for DIY MB owners and those helping MB’s owners. Extremely informative, well put together, perfect pace, audible is clear, with no background interrupting noises. You explained each step, to include the tools to use, any points of caution ⚠️, I own two 450SL’s and with your very helpful video, I plan for my teenage daughter and I to perform this PS fluid change on both cars. Great teaching tool. Thank you very much. I have shared your video with just about every family member, friend, colleague, car enthusiasts I have in my contact list.
I am excited to see more of your video and to learn about DIY MB maintenance! 👍🏻😎👍🏻😎🙏🏻✝️🇺🇸🙏🏻✝️🇺🇸
Thank you and many, many thanks. Your feedback is encouraging and thanks for sharing it with others. Great idea to get the family involved. My ‘production/video assistant’ is my teenager.
More videos are on the way.
Val you are the best!!! always 5 stars!!!!
Thanks Mark! Much appreciated. I find changing this fluid and filter very satisfying and I think many also enjoy doing it.
Much easier than the last video I saw 👌 thanks a lot.
Very useful - I think the turkey baster is a lot easier than fiddling with the pipes even though it may use more fluid
Thanks Val, going to be doing this service in the next week or so.

Why not use the steering box drain plug MB has put on the bottom of the steering box to drain it all at once??
There’s different ways to go about changing/refreshing the power steering fluid. The video shows the easiest, cleanest and safest way to go about it - and by easy/safest I mean it doesn’t involve jacking the car (which can be dangerous if not done properly), removing any rubber lines or plugs that given their age may or may not seal any longer once removed and put back in place or worse deteriorate when handled in removing them. The intent of the video was to avoid these issues.
for my hyundai azera i learned very late that this forgotten steering fluid reservoir have built in filter! & when it's clogged it causes poor stability or some times dangerous drive! i was pulling my hair to figure out the cause unstable steering my car! by the way all you need to drain the fluid is from the return pipe of the reservoir then jack up the car & turning the steering wheel repeatedly both ways (without starting the engine) untill it drained out
Thanks for sharing - power steering is so often forgotten. Many of the newer cars have the built in reservoir and filter. It’s definitely a bigger job than replacing the filter only like in the older Benz. With these older cars, I worry about pulling hoses off as they can tear and then require a new hose or clips or washers, etc. On newer cars, I agree with removing the hose and draining it that way as there is less risk of anything breaking…but not everyone is comfortable jacking their car either. All this to say, there are pros and cons.
Okay,it’s semi done today,but I think I need to order one more liter just because the fluid color should be like young whiskey and I don’t have that color yet… it shouldn’t be reddish or brownish. Just like pale whiskey
Nice - you’re almost done. An extra liter will certainly get you the desired results and keep the steering mechanism working well for a long time. 😃
Excellente view and explain, many thanks, i have a question.. it's normal after fluid chang or change the Power Steering Seal Ring Box to make more heaviness on the steering wheel ?
Thank you. A change in power steering fluid typically should make steering easier and smoother, not heavier. Is it at least a smooth feel? Did you remove the fluid with a turkey baster as in the video, or did you drain the fluid? If you drained it, then filled it, it could be that the fluid hasn’t reached all the power steering parts. In this case try steering fully left to right a few times. Let me know.
@@HandyValmy car is W140 S500 1996, I had a liquid leak at the power steering gear box. i used a new seal ring and the liquid also same type it's Febi. But after the work was done I was surprised the heaviness in the movement of the steering wheel, it was soft before that work. I will make sure that the air is completely discharged from the power steering system and I will inform you about the results ..
Hello question ?
Trying to check my power steering fluid but I can’t find it .I have a mercedez GLc 300 2020 .
Any ideas where is located?
I believe it’s on the right hand side of the engine, near the front of the engine compartment. The cap should be plastic and somewhat resemble your coolant reservoir cap. I don’t think you need to remove the plastic engine cover to get to it. I hope this helps.
@@HandyVal thanks for the answer I will look again but I’m sure I didn’t see it anywhere
I have a c124 ‘94 coupe. Can I take the filter right out at the start to get more old fluid out, then refill to maybe cut down the number of refills. After 2 refills I would Install new filter. Or would that be risky?
The coupe is a great looking car. What you suggest can save a few iterations of drain/fills. If the car is a regular driver then I think you can remove the filter and try as you suggest. The risk is if the car isn’t a daily driver, and the process of turning the wheels creates debris to be released - for this you want the filter there to pick this up before redistributing the fluid with debris (maybe in smaller chunks) back to the steering components. I hope this helps. It’s always safer to keep the filter in place.
@@HandyVal good point about the debris, I hadn’t thought of that. I drive the car daily and it’s in excellent condition. I’ll err on the side of caution and keep the filter in place while replacing fluid. Thank you for sharing your knowledge and helping me learn more about my car, and to take better of care of it. 👋 Dougie from Australia 🇦🇺
FYI - the fluid is very dark brown in colour and checked all the garage documents…. I don’t think the steering fluid had been replaced for quite a number of years.
@@benzcruiser1602 I believe it. The power steering fluid is often neglected by owners. Even though it’s a cheap to replace and a simple process. It’s good that you’re replacing it.
Is this the same for the M119 SL500s?
M119 is an amazing engine! Yes - The M119 SL500s shares the same power steering system as the car (300SL) shown in the video. Further, both use 1.0 L (or 1.1 US qt) of power steering fluid. Everything in the video is applicable. Thanks for watching.
do you change differential fluid ?
It's a good idea to change the rear differential fluid every 30,000 miles (50,000 km).
Not very efficient. Yesterday flushed the fluid on ML350 by removing the return line and sucking the stuff with a vacuum pump. A 5 min procedure and you can run the engine rotating the steering wheel from lock to lock as much as you want. The tricky part there is to remove the clip around the hose, which took me an hour to figure out, but with the saw grinder it has worked .
Thanks for sharing your experience. I agree, the method I show in the video isn’t the most efficient. The most direct way would be to use the return line. It adds more complexity to the job and risk. If you go this route, in older cars the hoses/seals may be brittle and may need to be replaced. As well, you still need to run fluid in and out and care is required to ensure the pump is never dry of any fluid.
I love the vacuum pumps! I use it regularly for oil changes. I think it belongs in every home garage.
Not very efficient spending 1hr on hose clip
In the absence of knowledge, the cheapest way is to take the car to the service center, but with a sander around flammable liquids... thank God that you are alive and well because one man caused such a fire while cutting a hose clamp with a sander, the spark caught the fuel and set the car on fire. his house and his neighbor's barn, where 34 chickens were burned, and the man ended up with 4 degree burns, and the car was left with only one ugly dent after that burning, which even today reminds of a beautiful Mercedes-Benz Phulman that due to curiosity and ignorance of a layman just for the reason that he could get by cheaper, he did incalculable damage to himself and others. 😢
ITs better to open the return line ino the bottle and flush with fresh fluid
I agree that opening the return line is a more efficient way of removing the old and then filling with the new. My concern given the age of the car is that the removal of the return line may create other problems - like not sealing properly when putting it back on, or simply breaking the tube because of its age. It’s for these reasons I recommend the turkey baster method - it’s less risky.
@@HandyVal No worries it will not leak, More risky was putting yellow fluid new MB fluid instead of ATF
Great!!! I’d rather use 5 bottles and pay $50 than paying $200 or more for labor!!
This power steering job is very satisfying and easy to do. The price of labor nowadays is crazy! Thanks for watching and thanks for the comment.
