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

In this video, Bryan and I change EVERY fluid on my 2017 BMW 340i. We changed the oil, coolant, differential fluid, transmission fluid and brake fluid. As with any DIY, work at your own risk.
While these fluids are fundamentally simple to change, a lift will make some of them MUCH easier to change. Big thanks to Bryan and Kies Motorsports for offing his expertise and access to his shop!

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.

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 ?

Hey Justin! I saw you at the Woodward dream cruise! I was in my black e90, a 2011 328xi. I tried to message you off my moms instagram because I don’t have it.

[@bigred3282]

Great video as always. What would you estimate was the cost to replace all the fluids? I see the transmission pan and tools probably added around $5-600+ . So maybe around $1000 total to get all these changed out?

[@justinbuice]

I have to add it all up, but $1,000 sounds very close. Keep in mind that most people will re-use the stock transmission pan which would be a big savings.

[@justinbuice]

I’ll add it all up today and then reply to this. BMW switched to electric power steering around 2012 so there’s no steering fluid 😎. I appreciate that!

[@BoliDropz]

@@justinbuicewhat’s the answer?

[@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.

[@justinbuice]

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.

[@jpt757]

@justine, thank you for this video, well presented. Please, I have a question, @3:31 after the engine oil, Cebatec was added. What is the purpose of adding Cebatec?

[@justinbuice]

It’s a protective additive that reduces wear and tear on the engine.

Awesome video. Been looking at 340is for the past year and the plan is to get on in December. Any comments about what tools I should start to accumulate? This will be my first real project car and I’m not sure what I need!!

[@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.

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

Can you share the frequency (years/mileage) of each one of those liquids?

[@MikeyMeM3]

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]

I’d say it’s probably fine for now. But personally I’d change it sooner than later. That way you can start fresh and know exactly what’s in there.

[@John-yh9wf]

Great video. Ceratec: some people recommend adding it before the oil. Might not matter.

[@justinbuice]

Thanks! I’ll keep that in mind next time

[@alexhentschel1080]

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.

[@abhisheknilajagi4960]

Any recommendations on intervals for brake fluid change. B58 2019 F36 GC

[@justinbuice]

2 years for brake fluid. Hard to find a specific interval for these cars but generally 2 years is a good interval to change it.

[@MrLanceDUB]

Awesome video Justin, the crazy part about this project is it will be obsolete in a few years with EVs. This will truly only be a passion project in the near future. We are in a sea change environment in the auto industry.

[@justinbuice]

Thanks! You are right, but I think that as that change happens, a lot of people are going to cling to their ICE vehicles, and will keep them running at all costs. We are in the last generation of cars that the average person can work on themselves 😢

[@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.

[@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

Hey Justin, thanks for another great video! I'm about to service the transmission of my 2018 BMW M240i X-drive and I bought a ZF pan & filter with 7 Liters of Liqui Moly Top Tec 1800 ATF. But now I'm hesitant to go with Liqui Moly because there will be about 2 liters of the factory ZF fluid left behind and I'm concerned about mixing them. Am I correct in assuming this is what you did and if so, have you noticed any changes in the performance of the transmission?

[@user-qw7nr4jc9o]

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.

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.

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.

How many quarts of trans fluid did you end up putting in after draining it?

[@leebenstead7171]

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.

[@justinbuice]

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.

When discussing the transmission fill process, (between 16:50-17:10) did he mean to say Fill Plug rather than Drain Plug? If you run the engine until the trans fluid reaches 40C, then remove the Drain Plug to check the level, all the fluid will start draining out!
