How to Change EVERY FLUID in Your BMW | OIL, COOLANT, ZF 8 SPEED, DIFF, BRAKES

quick disclaimer before we get started always work at your own risk and if it's your first time doing any of these I'd highly recommend working alongside someone with some experience now my car what you're going to see in the video is a 2017 340i it has the b-58 engine and the ZF 8-speed automatic transmission now BMW has used both the engine and the transmission in many of their vehicles from around 2016 to the present so even if you don't have the exact same car as me chances are at least part of this video will be applicable to you this is going to be a longer video so I haven't broken up into chapters feel free to skip around grab what you need or bookmark this video for a later time [Music] [Applause] today we're going to be changing every fluid on the 340i we've got all these fluids here and we're going to try to be as detailed as possible with this but I kind of want to give you guys an overview of how all these different fluids are changed and you can decide for yourself which ones you want to tackle at home and which ones might be easier to just take somewhere you're going to see in the video some of these are going to be a lot easier to do if you have a lift uh so yeah we'll just show you how to do it and you can decide for yourself uh which ones you want to try at home [Applause] hey my name is Brian at keys and today I'm going to be helping Justin out with all of these fluids starting with the oil now when you're changing your oil you want to make sure that you have a BMW approved oil for your car for Justin's car he needs a zero w20 so we have the liquid Molly top Tech 6600 we have the zero w20 and you want to make sure that you have a BMW long life 17 Fe certification otherwise if BMW really wanted to they could void any warranty you may have left so with that let's get started [Music] remove the 17-millimeter drain plug and have something ready to catch the oil remove the acoustic engine cover to access the oil filter you'll need a 32 millimeter socket on a swivel extension to remove it with the oil filter out of the car what you want to do is separate it from the plastic housing just by pulling down like that and then it's very important to replace your ceiling o-ring so all you need to do is just pull up or use a pick tool and then slide that off and then in your oil filter kit [Applause] you're going to have your brand new filter and you're going to have a new Crush Washer for the bottom and then your new ceiling o-ring you want to make sure that you take it and get it into this groove right here otherwise you may have an oil leak so we'll take that put that there like that take your new filter small end goes this way clip that into place like that and then take a little dab of your new oil and lubricate the lower and also the upper O-rings then we can reinstall it in the car [Music] reinstall both the oil filter and the drain plug and torque them both to 25 Newton meters [Music] you are watching a master at work and to make sure Justin gets the most protection possible we're going to be adding in ceratec which essentially ceramic coats the inside of your engine for Superior wear protection [Music] all right so now that the oil change is done it is time to change out the coolant if you take a look over here the b-58 engine has a high temperature coolant system and also a low temperature so with that let's Jump Right In [Applause] [Music] jack up the car and remove about a million eight millimeter screws to access the bottom of the radiator [Music] [Music] there's a little clip here [Music] once the clip is released hold the hose straight back and get ready for a waterfall [Music] and then that way it just snaps on so when you snap it on these two little pieces in here they just and then you hear the audible click a little trick for reinstallation if you take a little silicone and you apply it to this little o-ring in the inside it's going to make it a thousand times easier to clip it back on [Music] the other thing when you're removing and reinstalling coolant lines you'll see that there's this little Notch at the bottom and then you'll also see that there's one here so if you try to twist it it's not going to do anything and when you go to put it back in you have to make sure that you line up that bottom Notch and also the top one up find where it goes now with silicone it'll slip right on do the same thing on the other side as well unclip the hose and pull it straight off [Music] all right for the f3340 it requires BMW's blue coolant some of the newer cars are now taking green but Justin's is still the blue one so it's a 50 50 blend of BMW coolant and also distilled water typically it's going to take three or four gallons or so so we like to mix them in one of these five gallon jugs makes it super convenient have you ever slipped and fell in here all the time all right so at this point all of the coolant is out of the system and we need to put new coolant in but it's not as simple as just pouring new coolant in like you do with your oil what you need to do is you need to get all of this air out so what we do is we use this little device right here it's called a vacuum bleeder and what it does is you put it on here on your coolant tank and it's going to create a vacuum and it's going to pull out all of the air out of the system and then from there I'm going to flip a little switch over there and it's going to replace all of that air with our freshly Blended coolant so at this time let's make it happen this is my valve that controls if air is getting in or out of the coolant system and then from there I let the airflow go through and when the air is flowing through here it's creating suction as you can see up here so once this gets to 25 I'm going to close it off and then what you're going to do is you're going to watch the gauge and if it stays with 25 you have a perfect vacuum if it starts to go back down that means you have a pool so we'll be able to test your system as well especially since this side was a little bit low [Music] and yours is steady so you don't have any kind of leaks or anything and then when I flip the switch this coolant's gonna fly out of here okay [Music] and then what I do I typically stop it and then I create another vacuum in the system whatever happened once it starts to get full it won't go all the way then we can stop that let that ride out then I can release the suction [Music] remove any excess coolant from the reservoir so that the level is between the minimum and maximum on the marker [Music] now that we've filled and bled the main system let's do it on the secondary system [Music] [Applause] [Music] thank you [Music] next up we're going to swap out the diff fluid now because Justin's car does not have a limited slip differential there is no drain plug on the bottom so what you need to do is remove the fill plug and then you take a little tube and then you're going to extract the fluid and then you're going to top it off to get to that you're going to take an E12 and remove this bolt here okay and then you're going to have access to the actual drain the fill plug is a 14 millimeter Allen [Music] so one of the things that makes this a little bit more difficult without the right tools is you want to make sure that you have the car level and in the air in the air obviously because you have to be under the car safely and then level because for the fill process once we extract the fluid you're basically just going to fill it until it starts to dribble out and then you're going to reinstall your drain bolt why don't they give you an actual amount of fluid I don't know it's just one of the things that BMW does but if you have the car jacked up too much in the front or the rear you could under fill it or you could overfill it so always make sure that you have the car as level as possible so now we're going to use as a basic extractor we're going to stick the hose in here and you'll notice that I added a little hose this is actually line that we use when we do water meth injection because that helps actually twist down so that I can get as much of this out as possible [Music] all right so after about five syringes or so full we are at a point where we are getting not a dribble oh there we go nevermind found some more all right so now this is all cleaned out what we can do is fill it with fluid and basically just fill the diff until it starts to overflow [Music] then you can reinstall your drain bolt and torque it to 60 newton meters [Music] foreign [Music] [Music] all right we are moving right along here next is going to be the transmission fluid and while we're at it we're going to be replacing the transmission pan with this cool aluminum one so of course the BMW the stock one is just made out of plastic and I don't care what anyone says anything that's plastic on the car can break this should hopefully be a little bit more substantial and this kit comes with all the hardware and the filter too [Music] remove this underbody panel as well as the exhaust support that's in the way of the fill plug [Music] we can do is we can drain the fluid out of here the best way to do it is to start by releasing this drain plug right here and then what you're going to do is you're going to loosen this side more so the whole pan will actually drip this way this is going to make sure you stay as clean as possible because this does get pretty messy okay so loosen this with a 10 mil [Music] I'll tell you jellyfish if you're going to use some kind of an impact to remove these screws always start by doing it by hand to at least break the tension otherwise if you go too fast and furious you could snap the studs off and then you're in for a much bigger project than your bargained for [Music] t40 bolts for the oil pan remember to keep a few Loosely installed at one end so you can angle the pan down and drain any remaining fluid [Music] yep all right now we're going to do is take a clean microfiber towel and make sure the ceiling area is as clean as possible cleaner you get this the better your seal will be so before we install this we just have to set up the filter so it's going to come with the filter and all the hardware that you need so this is just going to go in this little insert here this is like a cutout for it and then you're just going to align this little chimney part with the corner it has instructions so you'll know what to do when you install it and then you just grab your Hardware so this is going to be the little black screws that it comes with just kind of hand thread them to get them started so then we're just going to put a little bit of that fluid on the new gasket put some fluid on the outer gasket as well before installing it on the car be sure to follow the sequence when torquing the bolts after they're all torqued to 10 newton meters to go back and double check them to make sure that they're all within spec all right now that's all torqued down we can install our drain plug which as you can see here has a built-in magnet so if you have any metal floating around it should grab it which is going to help save your trans foreign now what we need to do is the fill process for the transmission this part does get a little bit messy as you can see we have liquomoly top Tech 1800 we have a little barrel of it typically you just got this in smaller containers but we use it quite a bit so we get this so I just transferred it into a gallon jug and we are going to do the first fill and then we'll show you what to do from there you go until it starts to leak out I should also point out we're changing this at 60 000 miles BMW is a little ambiguous about the transmission interval but ZF the company who manufactures these recommends 50 000 mile intervals [Music] drain plug back in all right now that the first fill is completed what we need to do is start the car and watch the transmission temperature and wait till it gets to about 30 to 40 degrees celsius then what we're going to do is we are going to take out the drain plug see if any fluid comes out if not we're going to fill it again with fluid until it starts to come back out and then we're going to reinstall the drain plug and we have one more heat cycle process we need to go through to check the transmission temperature we're using Beamer geek's Pro Tool feel free to use whichever software you like the control live parameters [Music] [Music] with the transmission up to temperature engage Park and hold the RPM at 2000 for 30 seconds then with your foot on the brake engage Park reverse drive and then D1 and D2 holding each position for 10 seconds this shot is sped up so you didn't have to sit through a minute of Shifting Gears you're welcome all right after you do this we just got up to 35 degrees Celsius if you're used to Fahrenheit it's pretty hot don't touch this because you will burn yourself pull out the plug with the engine still running unscrew the fill plug since no fluid came out we'll fill it until it overflows from the fill hole note that the engine must be running for this step to get a proper level alright so it looks like our fill is sufficient so I'm just going to let this settle down a little bit I'll put this back in and then we'll torque it to spec torque this down to 35 newton meters and we're done [Music] all right last but not least we are going to be installing some liquid Molly race brake fluid so to do so we have our motive bleeder and basically we're going to pour our fluid into here we're going to pressurize this and then we're going to go around and we're going to bleed out the brace get the old fluid out and get this new high performance fluid in and then Justin's gonna be all done [Music] all right so to get this started what we do is we put in four of these bottles so as you can see these are 250 mils each this should be enough if we need more we do have more on hand basically what you want to do is you want to start with the brake furthest from this Reservoir up here so that's going to be the passenger rear then you go to the driver rear then the passenger front and then up here um the way that you tell when the old fluid is out and the new is in typically you'll see a color difference now he just did this not too long ago so it might be very subtle because this fluid is probably very clean but you should still be able to notice the difference [Music] all right so then you get one of these little catch cans and you put the silicone hose on the back of the bleeder screw and basically since the system is pressurized it's like what you used to do in the olden days or what Justin does now is you push on the brake pedal but anyway since the system's pressurized the fluid will start coming out [Music] all right so as you can see in there it's all dark and nasty but in the tube it's nice and clean so that tells us that this one's done so I can close that bleed screw back up and then we can move on to the next one [Music] foreign [Music] all four corners remove the bleed screw cap attach your hose then loosen the 11 millimeter bleed screw the pressure from the power bleeder will force the old fluid out once you see clean new fluid coming out through the hose tighten the bleed screw and replace the cap now if you have this style brake setup what you want to do is make sure you get the one on the front and the one in the back the ones in the rear just have one liter the ones in the front have an outer and they have an inner so make sure you do both [Music] thank you [Music] so once you get done bleeding the bricks you just want to hop in the car and pump them up and you should be good to go if you can tell we're really exhausted right now because the show was yesterday we just pushed through this today to get it done but thank you so much for all your help man I'm going to link all the products and everything down below you can find everything online and you can follow him at Keys Motorsports on YouTube Instagram and uh yeah thanks for watching and we'll see you guys in the next one see ya thank you [Music]
