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

[@justinbuice]

At 16:55 when Bryan explains checking the transmission fluid level, he meant to say "fill plug" rather than "drain plug." You will use the fill plug to both fill and check the level. DON'T take out the "drain plug" after adding fluid or it will all pour out on the ground lol.

[@yeisonmunera8701]

Hey bro question i have a bmw x5 e70 2012 n55 engine with 119k miles i bought a transmission fluid kit from fcp euro i want to know if is safe to change the fluid or is too late now i call the bmw dealer and they told me is not recommended what are your thoughts the car shifts perfect with no problems ?

[@theoutsider6191]

Hey guys, just bought a M240i used, first registered Jun 2019. And it also has the B58 engine in, with the same setup for coolant reservoirs as you have. The main engine coolant reservoir was a little low on coolant so i got some from BMW yesterday (green for 2019 on) and a syringe and tubing to sample the reservoir since i could not actually tell if the coolant in there looked the same (some folks will use non BMW stuff, so best to check before adding). The coolant in the main engine reservoir was yellow, so not the green coolant BMW stated is used in B58s from 2019 on. It is clear and clean looking with no residues or particles evident (good news as i believe if there was oil from engine or transmision it would not be, similarly if there was a rust problem) and interestingly if you pass light through it at right angles to viewing direction it is bright green like the proper coolant. Would you say this colour change can happen to coolant over time where it will change colour like this? And also, being as the reservoir for the intercooler (smaller reservoir) contained green coloured coolant and was at the correct level, i assume the two systems are completely independent of one another, am i correct?

[@See.M.Swervo]

Wow. I’m going through the same thing but opposite I have like a yellowish green coolant in my low-temp reservoir. When I shine light in it as well it is green. Super weird I need to know how to drain the low-temp reservoir I did a flush over thr weekend but I only did the high temp.. I have the f30 340

[@theoutsider6191]

@@See.M.Swervo I took mine in to BMW within a week of buying it and had them drain and replace 🙂 Correct stuff in there now. There are a few videos of how to drain this fluid out and flush. I don't have a garage/drive so could not do this myself really.

[@Tht_f30]

Great job fellas. The detailed instructions are definitely helpful 🙏🏾

[@justinbuice]

Glad we could help! 😃

[@mathiasliden9403]

Just want to add that when changing the oil filter, loosen the plug on top of the filter to allow contaminated oil to drain for a while. This prevents metal particles from being flushed back into the engine when the filter is removed.

[@ProcTech]

Not gonna happen at least while we are still alive. Maybe the next generation or after that. This fear of EV taking over is over exaggerated.

[@dskim9242]

Before filling differential oil, we need to shake the oil bottle to mix everything evenly inside. Otherwise, friction adjustment will differ, and it ends up chattering

BMW factories use ZF 8hp fluid in their transmission. You have added luqui molly which differs from ZF. BMW warns that mixing a different fluid can cause damage to the transmission. That’s why I ordered ZF. What do you think about that? Because couple litres old oil was left in transmissions anyway.

[@AbstractJan]

There is a ZF Gearbox service kit with pan, filter, screws, and 7 litres of oil included. Costs around 200 euro.

Resetting the adaptations is not mentioned in the BMW service guide or the ZF service guide.

No, you dont need to, you reset adaptations when rebuilding the case, or change mechatronics. Important is after the adaptation reset you need to run new adaptation procedure.

[@TheJaredsalinsky]

Great video. Thanks. Very helpful. Question about the coolant - what if you don’t have a pressure bleeder? Is it the typical ‘leave the cap off and let the car idle for 15 minutes so it can believe itself’?

[@ericsivilla4091]

I just got a 2024 530i, also factory filled with 0w20. I felt it was a bit to thon. I asked the BMW dealer, and the service dept. they told me tgat they use 0w30 after 60k to 70k high mialeage. However I could request to use 0w30 on my next pil change and they would no prob. They said the ow30 provides more protection, , but the 0w20 is for better fuel economy. Then I asked if I could use 5w30, and they said I could, and they have it, but 0w30 flows better. I'm in Miami. Not sure where you guys are at, perhaps the extreme heat we have here , BMW has different fill options. I personally prefer the 0w30

[@deblober89]

Do you add the exact same coolant to both cold and hot fill sections? And do you go to the max or go for the middle of min and max fill? Love the videos very helpful!

[@neilhanks]

@justinbuice For the coolant change there was some editing. Right after you empty the system and have full vacuum, the inlet hose was empty. Then video cut to next step with inlet hose full before filling new coolant into system. It looks like you skipped a step. If you don’t have that inlet line full of coolant you’ll be injecting the air that’s in the line into the system. How did you fill the inlet line first?

Question about doing the transmission pan. Why are we cleaning the mating surfaces on the transmission of fluid with a microfiber cloth.. if we are then putting some transmission fluid on the new gasket to lubricate it? Doesn’t that defeat the purpose of cleaning that off in the first place?

[@simonsays582]

In about 1000 miles im due for a oil change. So for my 2014 228i RWD Coupe, I ordered 5w30 Schaeffer's Advanced European Performance. The BMW dealership said originally the weight was 5w30, but changed it to 0w30. I said screw it im gonna keep it 5w30. Schaeffer's been around since 1839.

Really great videos, I love all of your content. And this is very good as a walkthrough, even for us who is used to mechanical work. Just easier to be prepared with tools etc, instead of going out to check what I need. I love how meticulously you are doing it. But as a request, please use gloves. Hands is really hard noticing it but I’ve had oil splashing other parts, like legs. It’s not many minutes before the oil actually gets absorbed into the skin. I lost a grandfather because of cleaning and rebuilding engines with hands in diesel and kerosene and oil all day long. So please stay safe and make more good work👌🏽

if i am not mistaken from the other videos i have seen you just open the air bleed off valve on your coolant turn you car on but not full set the temperature to high and fan to low then bump on the gas pedal for about 10 seconds or so

[@suryaprihadi2258]

Some job need extra or special tool to do it properly. Example good torque wrench. Modern cooling system due to very high efficiency heat exchanger using micro channel is best to use vacuum type refill kit to avoid small stubborn air bubbles pocket. At say 25 inch hg vacuum mentioned in this video, it is equal to as though as we are filling coolant at 12.5 psi positive pressure, but in the form of suction.

[@justinbuice]

BMW’s service documents state that the B58 coolant should “only” be replaced using a vacuum

[@anthonyriche552]

You can try leaving the coolant cap off overnight. This will generally release all the air bubbles in the system. I used to do this on my e34 and e39 and it worked everytime.

I have a 2017 430 and bought some blue coolant because I got a warning light on for low. However I'm aware that they started using green coolant so if the dealership topped off my blue coolant with green coolant would I need to use green or blue to top off? I read that you can use green in blue but not blue in green so I'm a little confused if I should add blue or green even though the car originally came with blue. I just topped off with some water for the time being.

[@justinbuice]

Hey! At the very least you will need metric sockets, a set of both Torx and E Torx sockets, a torque wrench, and some sort of software that can interface with the car’s computers. A set of interior pry tools will be helpful too. I personally use BimmerGeeks ProTool which is an app you can get for android devices. I got a cheap tablet from walmart just to run ProTool. You will need this or something like it if you ever replace the battery. It can also show live parameters like how we were able to check the transmission temp in the video. You can also use it for programming if you change any of the electronics inside the car. For example i Installed a digital gauge cluster a few months ago and used ProTool to program it to the car. I also use an app called Carly which doesn’t have quite as many features, but it’s more convenient for me to use on the go since it works with iPhone.

After watching/reading various how tos regarding the transmission refill, apparently, after carrying out the procedure in the video one should either add 0.5 ltr extra of oil, or, run the transmission until the transmission cooler opens (75°C), then let the trans cool back down to 40°C, and recheck level. Obviously this depends on whether or not a cooler is fitted.

We were following the service PDF from ZF. After shooting this, we test drover the car, let the transmission cool down to 40C, took out the fill plug, and there was still a steady stream of fluid coming out.

What oil should I use for high mileage bmw?

[@tteitei]

Hi, I was wondering if you rechecked the transmission oil level after driving the car and letting the oil cooler thermostat open at 75 degrees? According to the ZF fill instructions this step is needed for all cars with an oil cooler. Actually they say to 'overfill' the trans 0.5 liters and then go for a drive. Not sure how you can overfill it without spilling allot of fluid.

We did re-check after going for a drive and the level was good. As far as overfilling, if you use a syringe or pump, you’ll be able to push fluid in faster than it flows out. Just have the fill plug ready so you can quickly screw it in. It’s messy so keep a pan underneath the car to catch any excess that overflows.

Do you add ceratec after the oil is already at max capacity? or do you add slightly less oil to account for the ceratec being added?

[@justinbuice]

Put in slightly less oil to compensate. Just make sure you check the level through iDrive afterward.
