@swizz85 In flushing the system, simply remove and add fluid (as shown in the video) until the circulating fluid is nice and clear. This generally takes from 2 to 4 quarts. Once the fluid is flushed so that it is continually running clear, you can adjust the final fluid level. This is accomplished by screwing on the cap (and integral dip-stick), with the engine running, and reading the fluid level. We actually forgot to show this, since we have an experienced "eye", for the proper level.
Solid video, just finished doing this job on my E39. I replaced the hoses as well - it was easy enough and I think if you're going through the motions of replacing the resevoir/filter you should probably do the hoses as well. Thanks BavAuto for a fantastic DIY video!
Okay , let me be the first to say thank you for the most basic common sense dyi video . You made me like I was working on my Honda again . My 10 month old was in the car with me when my power steering started to fail . Was a crazy experience! Thank you so much for this video ! I’ll be coming back later probably a thousand times to walk myself through when I replace the power steering . Thank you again !
When the cap says ATF, this is Dexron-III automatic transmission fluid. this fluid is quite commonly used for various hydraulic systems, such as the power steering system.
Yes, your reservoir will be the same as the one shown on this E46 3-series (99-05). The location is slightly different, but the procedure is similar. If you remove the air filter box and the air flow meter, you will have full access to the hose clamps on the reservoir. Use the same fluid (Dexron-III). All is available in our online store at bavauto.com.
Actually, these hoses did need to be replaced, but we did not have them available when the video was done .... and we were just addressing the fluid and filter change. Usually, the leakage is due to the original hose clamps no longer being tight enough to seal properly. If the hose is deteriorated or has any cracking (as this one did), they should be replaced and, of course, this would be a good time to replace the hoses. We do now keep them in-stock at bavauto.com
@Altair8801 - Yes, on the models that have the plasic reservoirs, the filter is encased in the reservoir. We would assume BMW never intended to actually change the filters as regular maintenance.
Great and informative video! One question: you mentioned early on in the video that the hoses that circulate the power steering fluid often deteriorate and result in leakage. In this video, though, it appears that you haven't replaced the hoses themselves. If there is leakage, then does that require a full replacement of the hoses in addition to the filter?
@bnigam - We do recommend replacing the reservoir (on the models with the plastic reservoirs), since the filter is captive inside the reservoir, and cannot be removed. Models that have metal reservoirs, with metal caps, have replaceable filters, down in the base of the reservoir.
@BiteDoctor - Red Line has named this fluid D4. We think this may be due to the fact that it meets the GL-4 fluid specs. The fluid is applicable to Dexron-II, Dexron-III, Mercon and Mercon-V.
@yukuhana - The fluid used in many (most) BMW power steering systems is Dexron-III. This is typically also used for many older automatic transmissions as well as manual transmissions. It is a somewhat universal hydraulic fluid and is most commonly known as automatic transmission fluid, even though this is just one of its many uses.
Also a good idea to turn the steering wheel both ways after adding new fluid. This way the old fluid in the rack and pinion is pushed out back to the reservoir.
We used our German hose clamps with size range of 16mm to 25mm. Our part number is CL 16-25 . we have them in our online store at bavauto.com. Flushing the fluid before replacing the reservoir/filter is certainly a valid approach. No, the fluid will not overrun the reservoir if the engine is running (unless you have it way to full anyway). The final proper fluid level is checked with the engine running, by the way.
thank you very much,I did it and it is working perfectly and I did not pay for change my e39 power steering filter,I changed filter,and I liked your work everything clear and clean,
The fluid will circulate through the system as long as the engine is running (turning the pump). We do typically cycle the steering left/right once in a while as we are refilling and removing/filling, to get the highest concentration of fresh fluid.
The hoses that connect directly to the filter reservoir, have quick-disconnect (QD) fittings on the ends opposite the slip-on ends at the reservoir. The QD fittings are next to the radiator (on the E46 3-series, as used in the video). There are special tools for the QDs, but you can separate them by wedging the QD connector away from the joint.
@ksvrando - We import the fluid pump from Europe. The brand is Bavarian Autosport, as we bring it in as our own. We all use these pumps, personally, and they work very well.
@OldUncleMe - All good points, and standard shop operating procedures, as well. The fluid pump and absorbent mats are offered by Bavarian Autosport at bavauto.com. We would not suggest mixing fluids of different base stocks in the same fluid pump. The pumps are not expensive, so having more than one would not be prohibitive.
@Thismexican1 - I'm not sure what you mean about an angle. If the reservoir dues not have the screw-on plastic cap, with a dip-stick, as shown in the video ... it will be one of the various metal reservoirs. These reservoirs have the filter ring at the bottom of the unit, with a metal plate sitting on top of the filter. When you drain the fluid and look down into the reservoir, you see the plate. People commonly think this is the bottom (or floor) of the reservoir. Hence, "false floor".
In general, yes, the procedure is the same as shown in the video. However, the reservoir is mounted in a less accessible location, under the intake manifold and behind the alternator (similar to the earlier M50 and S50 engines in the 92-95 E36 325i and M3 models and 91-95 E34 525i models). You must remove the air filter box and intake boot to access the reservoir.
@sunnyjason - If fluid is being lost, it will be due to leaks at the hose connection points, a leaking pump or a leaking steering rack or gearbox. An undercar inspection should identify the leaking areas. If fluid is in the boots on the steering rack, the seals in the rack are leaking and the rack must be replaced.
As noted in prior replies; Many of the BMW power steering systems use Dexron-III automatic transmission fluid. This is a very common use of the Dexron-III fluid in many vehicles, not just BMW.
Yes, once again very informative video. I am now anxious to do the same procedure for my car. I will put together a parts list and place an order. Thank You Mr. Otto. Thank You.
Great video!!! One question: If the filter and fluid are for power steering, how come we use ATF fluid? Doesn't ATF stand for automatic transmission fluid??
You may find that you have better access to the reservoir if you remove the engine air filter box, Air Flow Meter or Mass Air Flow sensor (depending on the year) and the intake boot. This would be similar for the 325i/is and 525i models that use the M50 engine and the 95 M3 with the S50.
As with any other filter, the purpose of the filter is to collect and hold the particulate contaminants that get into the system (or are generated within the system, due to wear). Eventually, the filter becomes saturated, or "full" and cannot hold nay additional contaminants. At this point, you have two negative issues, 1) You may be passing unfiltered fluid through the system. 2) The filter will be effectively "clogged" and the fluid flow will be reduced.
@ksvrando - We purchase the pumps from our suppier in Europe. There are in a plain white box .... no branding. However, they do work well for most fluids. We have fould that very heavy fluids can cause bypass at the piston (pump) seal, such as Lucas gear oil modifier (you should never use this stuff anyway .......).
Wait; If I'm understanding this correctly, at 04:10, you said that the hoses get soft & start to leak at the clamps. I believe a correct procedure, would be to replace the factory hose, with an OEM ear clamp, with sufficient clamping force. However, if you use those screw/band clamps, that would constrict the hose, & potentially flaring the end of the hose, making it easier to slide off under pressure. And yes, the parts counter always gives me a weird look, when I request the OEM ear clamps.
Well, the BMW likely does have a heavier steering feel than the Charger. We did drive a new Charger while traveling in CA (a rental) and noted that the steering was rather numb and highly boosted. As for the sound that you are hearing, we can't tell what it is, from here. you should have someone else take a look at it to get an idea what may be going on.
Oh ... you have the self changing fluid option! Very common on many BMWs. We can certainly get the leakage under control. Have you determined the source(s) of the leakage?
We like to change the power steering fluid about every two years. This can vary depending on how many miles the car is driven as well as the environmental conditions. Certainly change the fluid when it starts to become clouded ... less clear.
Hi! Great Video! Do you think it would be a good method to leave the return line of the reservoir disconnected, then turning the engine without fuel and "feed" the reservoir fresh fluid to completely flush the system?
@machiavelli316bg Turning the wheel back and forth, may help to move the fluid through the system. It certainly can't hurt. Keep the engine running through the complete procedure.
It is really ok. Wipe all with a towel insuring the hole in the cap is not clogged. You need to insure that your fluid cap shows the type of fluid as some models use CHF11S.
On BMW and MINI models with the plastic reservoirs, the complete reservoir must be changed, as the filter that is inside is not accessible. Earlier BMW models (and some later models) that have metal reservoirs, do indeed have replaceable filters down in the bottom of the reservoir. We also stock these filters.
Thanks for your reply. The color of fluid is clear and turned into light brown yellowish. I went to dealership and he also gave me CHF-11 but when I told him he said use what is on the label.
You may need to clean things up a bit so that you can tell where the fresh leaking fluid is coming from, but it's likely the hoses. The bar you are referencing sounds like it may be the swaybar.
No, just the steering system. Some older model BMWs use the power steering pump and fluid to boost the power brakes and even the rear self-leveling suspension.
this seams easy, we just ha an old -96 523 e39 restored, had all the rust done and the whole car repainted, it looks just stunning now for a car that has 285000km on it! I just have to change the hose under the power steering reservoir, its old and leaking a bit.
All that needs to be disconnected for complete flush as opposed to a dilution of the remaining fluid illustrated here is the low pressure hose. A continuous supply of fluid must be assured during this. I also recommend turning the wheel lock to lock in both cases to extract or involve all the fluid in the rack. This should be done slowly and deliberately twice, pausing for a few seconds at each lock.
Your best action is to try to flush the system as completely as possible. Either perform the steps shown in the fluid and filter change (including removing and emptying the reservoir), or even disconnecting the lower hoses at the pump and the steering rack to allow them to drain.
This is due to the left and right audio channels being out of phase with one another. When played through a monaural audio system, the two channels are combined, and being out of phase, they nullify each other. When played through a stereo system, it is audible, but very thin and weak sounding. This might be worth noting in future videos. I love this series, and will be ordering my new power steering reservoir today!
you need to turn the wheels, if you just let it circulate its just going to flow thru the lines and bypass and not clean the rack much at all. left the car, drain the rack, and turn the wheels.. then fill.. and repeat once more.
@TigerOscar78 We typically recommend having about 4 quarts/liters on hand, when performing the filter and fluid change as shown in the video. Go to bavauto.com for purchasing the proper fluids
@machiavelli316bg - The type of transmission does not matter, All late model US BMWs have power steering. The fluid reservoirs and filter types may vary from model to model, but the transmission type does not matter.
If the hoses are leaking where they connect to the reservoir, fresh hose clamps may cure the leak. However, if the ends of the hoses are swollen and deteriorated, you should replace them. If the leakage is at the points where the rubber hose is crimped to the fitting end (such as at the pump or the rack), the hoses must be replaced. You can check our online store at bavauto.com or call our advisors at 800-535-2002. As for the fluid, it does sound like it needs to be flushed.
If the label on the cap (or on the reservoir) says ATF vs. CHF-11 (which is the other fluid that may be used in some late model BMWs), then the Dexron-III ATF fluid will be proper (regardless of the color). You did not mention what color the fluid was. The Dexron-III is red, but ages into a gray or brown color. The CHF-11 is clear.
Your videos are awesome, thank you so much, I just bought my first BMW (2007 335i) it was well taken care of but I need to do several maintenance items which your videos show very well. Thank you very much
If you are listening on a Mono speaker system, like the one built into a computer, you may experience trouble with the audio. You do need a full stereo sound system, such as the common add-on speakers for a computer.
Nice video. I have a question. You did not mention bleeding the air out of the system like you would have to do with changing the rad fluid. How is that accomplished? Also if you run the car with and drain the fluid aren't you putting a stress on the power steering system since you are running it with very low fluid????
Thanks for the video! Three questions: 1. What is the min-max size of the hose clamps you were using? 2. Why didn't you use the old reservoir first and start adding fresh fluid until it's clear? That way you won't be driving dirty fluid through your new filter. 3. Also, if the fluid is full, won't the fluid spill out once the engine is on? Some people say that will happen :)
Yes, you can use the same procedure shown in the video. Just be sure you use the proper fluid as noted on the reservoir. We do keep all of the fluids in-stock (as well as the fluid transfer pump) at BAVAUTO dot COM.
@ViaDolorosa777 We would recomment changing the fluid and the filter at 30,000 to 50,000 miles, in most cases. If the fluid is dirty looking (not clear or bright red, depending on the fluid that is used), it's time for a change.
Wouldn't it make more sense to do the fluid flush BEFORE changing the reservoir, that way you don't drag all the old fluid through the new filter . . .
but then you drag new fluid thru dirty filter :p best way is to put new reservoir onto only one hose (pump suction) and cap other and pour fresh fluid thru fresh filter, till clean fluid flows from return hose, then connect the return hose to new tank and top up.
The flush can take as little as two quarts of fluid, or as many as four (or more), depending on how much flushing is actually required to get the fluid clear. In other words, how dirty the old fluid is.
not inside the engine, just around the assemblies. i fished around with a metal retriever, but didn't pull anything out. Thanks for the reply, your videos are great.
Your power steering system will be exactly as shown on the M54 in the 3-series in the video. You do need to replace the reservoir in order to replace the filter.
Good morning. Thank you for the video. I want to ask you: why do you change the power steering reservoir? is there a filter in the power steering network? Thank you.
The power steering system on this car used Dexron III automatic transmission fluid, as do many other BMWs. The proper fluid type for your BMW will be noted on the reservoir cap or the top of the reservoir. We carry all of the various fluids that BMW and MINI use for the power steering systems. You can see them in our online store at bavauto.com or call our advisors at 800-535-2002.
Certainly! The procedure shown is applicable to all of the various BMW or MINI power steering systems. By the way, if you have a metal fluid canister, these have filters as well. The filters are replaceable (without replacing the canister). they are located under the plate at the bottom of the reservoir. We keep these filters in-stock at BAVAUTO dot COM or call us at 800-535-2002.
WC Edgar - We can't reply directly to your comment on the BMW power steering filter DIY video. The filter is encased inside the reservoir. This is why we replace the reservoir.
Nice very helpful! what type of fluid should i use for BMW 325Xi 2002? it just shows ATF on the cap i want to know what brand is best for my car... thank you.
Yes, there was in issue with the camara's stereo recording, not working with the youtube systems. We have since rectified the issue, but cannot fix the prior videos without fully reloading them and loosing all history, comments and replies.
Forgot to add, I have a slow leak at the power steering hose(s) which is appearing as a consistent and small leak, plus the power steering fluid looks thick and not clear. Thanks for your tips BavAuto people! //Gary
thanks for the video! I'm wanting to change out the reservoir and power steering lines on my 96 750il...Can I drain the remaining fluid from the pump after the lines and reservoir are replaced, or should I just add the fresh fluid, then circulate it till its running clear?
Fellow viewer DahYohLim answered your comment as a reply. The fluid filter is encased in the reservoir. This is the reason that we replace the reservoir.
Try listening on a different device. We have found that computers with built-in single (mono) audio and speaker typically cannot play the sound track. Thanks for your notes.
Well, it actually is somewhat "normal". Of course, we'd like this not to happen. The fluid film is from the cap venting as the fluid in the system expands. As a first attempt to reduce or eliminate this, you could try a new cap and/or seal. The vent on the cap may be plugged or the seal may be in need of replacement. go to our online store at bavauto.com and ID your car as a US model (128i, for example) and search "power steering".
The plastic reservoir on your 528e is just like the one shown in the video. You replace the complete reservoir in order to replace the filter. Check it out in our online store at bavauto.com
@ViperKeeper2070 - There won't be much fluid in the pump, but you could drain out what you can. Once it's back together, do the fill and some fluid "swapping", as shown in the video, until the fluid is clear. Be sure to replace the filter too. The E38 750il models had three different fluid reservoirs. If you have a plastic reservoir (there are two different ones for this car), replace the reservoir. If reservoir is metal, replace the internal filter. Call 800-535-2002 or BAVAUTO dot COM.
You are very good at what you do sir.. I like your style. Btw, is there any kind of air bleeding required? Maybe turn the wheels from left to right with the reservoir open? And can the filter be replaced without having to replace the whole reservoir? Thank you very much. Im subscribing.
No current specific video on the E36, Lance. However... here are some pointers: Remove the complete air filter box, MAF and intake boot. This should give you working room for the reservoir and the hoses. If you are replacing the hoses, you'll also have to be able to get under the car. If there is a plastic splash shield remove the shield to access the hose connections to the pump and the rack. We do keep all of this in-stock. Just go to our online store at bavauto.com or call 800-535-2002.
bavarianauto you guys make the best most informative videos being a diy e39 owner i thank you zoo much this s about the 5th one i diD. HOSE CALMP SIZE?

The QD fittings are next to the radiator (on the E46 3-series, as used in the video). There are special tools for the QDs, but you can separate them by wedging the QD connector away from the joint.

Thank you for your time and videos to teach us. I really appreciate your time in showing me.
Good point on performing small fluid changes when you do an oil change, to keep the fluid nice and fresh.
Very informative, and incredibly clean work as always. Great videos
Thank you for the videos they've kept me from alot frustration
You may need to clean things up a bit so that you can tell where the fresh leaking fluid is coming from, but it's likely the hoses. The bar you are referencing sounds like it may be the swaybar.
hello.
Nice and clear video. ty 4 the post!

When played through a monaural audio system, the two channels are combined, and being out of phase, they nullify each other. When played through a stereo system, it is audible, but very thin and weak sounding. This might be worth noting in future videos. I love this series, and will be ordering my new power steering reservoir today!
you need to turn the wheels, if you just let it circulate its just going to flow thru the lines and bypass and not clean the rack much at all. left the car, drain the rack, and turn the wheels.. then fill.. and repeat once more.
yes, it is quite like that to do
@TigerOscar78
We typically recommend having about 4 quarts/liters on hand, when performing the filter and fluid change as shown in the video.
Go to bavauto.com for purchasing the proper fluids
@machiavelli316bg -
The type of transmission does not matter, All late model US BMWs have power steering. The fluid reservoirs and filter types may vary from model to model, but the transmission type does not matter.
If the hoses are leaking where they connect to the reservoir, fresh hose clamps may cure the leak. However, if the ends of the hoses are swollen and deteriorated, you should replace them. If the leakage is at the points where the rubber hose is crimped to the fitting end (such as at the pump or the rack), the hoses must be replaced. You can check our online store at bavauto.com or call our advisors at 800-535-2002.
As for the fluid, it does sound like it needs to be flushed.

You do not HAVE to use synthetic. The synthetic is just a better choice. The original fill was not synthetic.
If the label on the cap (or on the reservoir) says ATF vs. CHF-11 (which is the other fluid that may be used in some late model BMWs), then the Dexron-III ATF fluid will be proper (regardless of the color). You did not mention what color the fluid was. The Dexron-III is red, but ages into a gray or brown color. The CHF-11 is clear.
Your videos are awesome, thank you so much, I just bought my first BMW (2007 335i) it was well taken care of but I need to do several maintenance items which your videos show very well. Thank you very much
Welcome to the family, Mike. Be sure to get our catalog on the way .... www.bavauto.com
BavarianAuto Definitely will, thank :)
If you are listening on a Mono speaker system, like the one built into a computer, you may experience trouble with the audio. You do need a full stereo sound system, such as the common add-on speakers for a computer.
Great instructional video as usual Otto. Well done, and thanks
Nice video. I have a question. You did not mention bleeding the air out of the system like you would have to do with changing the rad fluid. How is that accomplished? Also if you run the car with and drain the fluid aren't you putting a stress on the power steering system since you are running it with very low fluid????
Thanks for the video! Three questions: 1. What is the min-max size of the hose clamps you were using? 2. Why didn't you use the old reservoir first and start adding fresh fluid until it's clear? That way you won't be driving dirty fluid through your new filter. 3. Also, if the fluid is full, won't the fluid spill out once the engine is on? Some people say that will happen :)
Yes, you can use the same procedure shown in the video. Just be sure you use the proper fluid as noted on the reservoir. We do keep all of the fluids in-stock (as well as the fluid transfer pump) at BAVAUTO dot COM.
@ViaDolorosa777
We would recomment changing the fluid and the filter at 30,000 to 50,000 miles, in most cases. If the fluid is dirty looking (not clear or bright red, depending on the fluid that is used), it's time for a change.
Wouldn't it make more sense to do the fluid flush BEFORE changing the reservoir, that way you don't drag all the old fluid through the new filter . . .
but then you drag new fluid thru dirty filter :p best way is to put new reservoir onto only one hose (pump suction) and cap other and pour fresh fluid thru fresh filter, till clean fluid flows from return hose, then connect the return hose to new tank and top up.
@Ponga Pandit You 'pump' it using steering rack - turning steering wheel back and forth from lock to lock, I used that methot and it works fine
The flush can take as little as two quarts of fluid, or as many as four (or more), depending on how much flushing is actually required to get the fluid clear. In other words, how dirty the old fluid is.
not inside the engine, just around the assemblies. i fished around with a metal retriever, but didn't pull anything out. Thanks for the reply, your videos are great.
Your power steering system will be exactly as shown on the M54 in the 3-series in the video. You do need to replace the reservoir in order to replace the filter.
Good morning. Thank you for the video. I want to ask you: why do you change the power steering reservoir? is there a filter in the power steering network? Thank you.
Great video. Do I need/should I, turn the steering wheel back and forth all the way to further flush through the system? Thanks.
The power steering reservoir has an o-ring. do you wet that with the new steering fluid to properly seal ?
The power steering system on this car used Dexron III automatic transmission fluid, as do many other BMWs. The proper fluid type for your BMW will be noted on the reservoir cap or the top of the reservoir. We carry all of the various fluids that BMW and MINI use for the power steering systems. You can see them in our online store at bavauto.com or call our advisors at 800-535-2002.
Certainly! The procedure shown is applicable to all of the various BMW or MINI power steering systems. By the way, if you have a metal fluid canister, these have filters as well. The filters are replaceable (without replacing the canister). they are located under the plate at the bottom of the reservoir. We keep these filters in-stock at BAVAUTO dot COM or call us at 800-535-2002.
Thank you such a clear and informative tutorial. I hope there are more videos like this.
WC Edgar - We can't reply directly to your comment on the BMW power steering filter DIY video. The filter is encased inside the reservoir. This is why we replace the reservoir.
Is there no way to replace the filter itself?
How do I know if mine has a filter (1991 E30 318i)?
+Mark Kanzler give me your car and i'll let ya know ;)
+rustypro98
I could make you a deal on it.
I'm probably going to clean it up & sell it in the spring.
Looks like you need to reupload your video. The sound is messed up, and then it cuts to black.
Thank you very much for your tutoring and knowledge. This will saves me a lot of money on my bmw 330i.
Nice very helpful! what type of fluid should i use for BMW 325Xi 2002? it just shows ATF on the cap i want to know what brand is best for my car... thank you.
Yes, there was in issue with the camara's stereo recording, not working with the youtube systems. We have since rectified the issue, but cannot fix the prior videos without fully reloading them and loosing all history, comments and replies.
Forgot to add, I have a slow leak at the power steering hose(s) which is appearing as a consistent and small leak, plus the power steering fluid looks thick and not clear.
Thanks for your tips BavAuto people!

thanks for the video! I'm wanting to change out the reservoir and power steering lines on my 96 750il...Can I drain the remaining fluid from the pump after the lines and reservoir are replaced, or should I just add the fresh fluid, then circulate it till its running clear?
Fellow viewer DahYohLim answered your comment as a reply. The fluid filter is encased in the reservoir. This is the reason that we replace the reservoir.
Happy Thanksgiving 2013. Great video. Compliments to the camera and sound man for jitter free training.
Thanks for the encouraging words!
Very nice video, I wish you where in the Chicago area I would use your service.
Try listening on a different device. We have found that computers with built-in single (mono) audio and speaker typically cannot play the sound track. Thanks for your notes.
Does my 2006 750I Power Steering reservoir contain a replaceable filter or do I need to replace the entre Power steering reservoir? Great video!
Well, it actually is somewhat "normal". Of course, we'd like this not to happen. The fluid film is from the cap venting as the fluid in the system expands. As a first attempt to reduce or eliminate this, you could try a new cap and/or seal. The vent on the cap may be plugged or the seal may be in need of replacement. go to our online store at bavauto.com and ID your car as a US model (128i, for example) and search "power steering".
i love it man...now i can change it. what will hppen if there is not enough fluid or not change it for a long time?
Low or dirty fluid can prematurely wear-out the pump and the steering rack or gearbox.
owh i get it..because someone told that as long u can use it..then use it :(
We recommend that the fluid be changed about every two years, or when it starts to become cloudy.
The plastic reservoir on your 528e is just like the one shown in the video. You replace the complete reservoir in order to replace the filter. Check it out in our online store at bavauto.com
The videos are great. I have a '02 Z3 with and M54. Are the p/s filters available separately or is it integrated into a new housing assembly?
@ViperKeeper2070 -
There won't be much fluid in the pump, but you could drain out what you can. Once it's back together, do the fill and some fluid "swapping", as shown in the video, until the fluid is clear. Be sure to replace the filter too. The E38 750il models had three different fluid reservoirs. If you have a plastic reservoir (there are two different ones for this car), replace the reservoir. If reservoir is metal, replace the internal filter. Call 800-535-2002 or BAVAUTO dot COM.
You are very good at what you do sir.. I like your style. Btw, is there any kind of air bleeding required? Maybe turn the wheels from left to right with the reservoir open? And can the filter be replaced without having to replace the whole reservoir? Thank you very much. Im subscribing.
No current specific video on the E36, Lance. However... here are some pointers:
Remove the complete air filter box, MAF and intake boot. This should give you working room for the reservoir and the hoses. If you are replacing the hoses, you'll also have to be able to get under the car. If there is a plastic splash shield remove the shield to access the hose connections to the pump and the rack. We do keep all of this in-stock. Just go to our online store at bavauto.com or call 800-535-2002.
We would change the filter whenever we flush the fluid. Either at around 36,000 miles or when the fluid turns opaque ... not clear red any longer.
bavarianauto you guys make the best most informative videos being a diy e39 owner i thank you zoo much this s about the 5th one i diD. HOSE CALMP SIZE?
awesome video and thumbs up!
My 745LI only has 75K miles on it and has this EXACT SAME ISSUE. That Normal?
