+Christopher Morales I think so 😉 Share! 🍻
Found this via your post on the forums - this is a great video, excellent timing and explanation. No background music? Awesome. Keep it up!
+fackamato thanks for the ❤️! And no, you’re not the only one that hates background music when it’s not needed 😎
Great video. Trying to understand the system and this is the best thing out there.
+Driver407 thanks! Hope you’re a subscriber now 😉
Great explanation of the system, cheers, been searching for my M2 comp
+art guy thank you! Hope you’re a subscriber now. 🍻
Brilliant video, learned exactly what I've spent many hours trying to find out. Thank you.
+@RS20O0 thanks! Hope you’re a subscriber now 😉🍻
Great video! Very well explained
Thank you 🙏
Thank you! Definitely valuable info!
+justin cupp thank you sir!
Thank you for this video, extremely helpful!
+bxsvx glad to help. Hope you’re a subscriber 😉
Very nice description. Thx
+Jeff Hirata you’re welcome! Hope you’re a subscriber now 😉
Got here from the f80 bimmerpost forum. Very good video. Thank you!.
+T Ng glad you checked it out. You’re welcome!
I do pretty much all my own work on my 16’ M3 and was actually thinking about the 60,000 miles on my coolant. This is excellent. Thx,
Subbed.
+Billy Johnson thanks! Nice to hear from another DIY’er. Coolant change should be out soon!
Great content
+Huan Nguyen thanks! Please consider subscribing if you haven’t 😁
Good, informative video. The vacuum fill tool, while a specialized tool, is actually not that expensive and is nice to have if you are an "intermediate" or higher level DIY mechanic. It is made by Schwaben and ECS Tuning sells it for ~$80. I have it and it works great. I have not used it on my F80 yet for either cooling system, but I have used it on my son's 128i with N52 engine twice. Makes the fill process seamless, with only one bleed cycle required to burp any residual air in the system.
+James M. Yes I was referring to the tool BMW shops have to get the fluid OUT. Putting it back in with a vacuum fill isn’t as bad, and probably what I will use since I have one.
Great video dude, Thank you!
+Mud Puppy thanks for taking the time to comment, I appreciate it!
I spent several hours trying to figure all this out and then I found your video and it had all the information in one place well explained It doesn't get any better than that!
Yeah I did the exact same thing and added calling a tech to make sure I understood it all correctly. Since I had him on the phone I added the info on the “official” way Bmw tells them to change the coolant.
Hey thanks man.
BMW recently released cooling videos for their current Gxx model, so I went looking for the f8x series and yours came up
+fightmeirl you’re welcome! Hope you’re a subscriber now 😉
@@HelpMeDIY Yea man, I have a '15 F82 as well so definitely am! and i like the diverse content. good luck bud
This was really well done. Thanks. Went back and watched all your M3/M4 content. Any chance of you doing a DCT fluid change in the future?
+Derek Hanson thanks a lot! I’m going to publish the coolant change today, and in sure I’ll tackle the DCT fluid eventually 😁
Amazing ! I look forward to the servicing as I will also attempt it after you on my austin yellow m4 😊. Btw can you also do a vid on how to service the differential oil?
+Zain Rj thanks! I’ll put that on my list. Nice choice of color btw 👍
Amazing Vid!
+J thanks! Hope you’re a subscriber now 😉
@@HelpMeDIY definitely! lol helps me with the BMW training currently attending in next hour 🤌
@@JimDaTech that’s awesome! Spread the word 😁
Very interesting video I’m going to start following you 👍🏼 you should make a video when you change your spark plugs.
+carlos ramos already done, search the channel 😉
@@HelpMeDIY thanks I just found it 👍🏼
This is great video. Thanks for your support. Are you going to make more DIY for f82? How about spark plug?
+Jun Mfour4 thanks! Yeah, more videos will be coming. Anything I do to it :). Apple CarPlay upgrade video coming this week.
Extremely interesting video. This answers a lot of questions I had.
A question: do you know how the S55 cooling system relieves itself of pressure in case the expansion tanks are not enough? I don't see a pressure relief valve in the circuit, nor observing the radiator of the car in your coolant change video. I'm intrigued.
+@mambodiehard that I’m not sure of
great great video. May I know where did you get those pictures? Thanks so much!!
Thanks! It was a hard copy printed manual that came with the car from the seller
Hey thanks for the video. Very informative.
Question: when filling up the expansion tank, do you put in the 50/50 mix of water coolant or just water?
thanks!!
+@humbertogamarrajr.3971 you’re welcome! Please subscribe to the channel 😉
Use the 50/50 mix if you can. If only topping it off at a separate time it’s ok to just use distilled water.
Hello, great video but I am wondering what book/ guide you're referencing that has all these diagrams. Keep up with your awesome m4 videos!
+Banana Boy thanks! Not sure where it came from originally. The original owner of my M4 had it printed out and included it with the sale of the car.
I believe he is referring to the official BMW Technical Training S55 engine document. You can do a quick google search and find a pdf to download. It is very helpful and gives a lot of insight
@@DJFlipsid3 thanks
do you know how to access the auxiliary coolant pump on the intercooler side? thank you
+peter t pretty much all I know is in this video and the video where I actually change the coolant.
Hey I have a ? So we’re is the thermostat?🤔
Hi,
Is it possible to provide some of the images you used in the video as a file or standalone image? Id like to have them saved to look at when working on my S55.
Thanks. Great video.
+Julian Arnouk thanks! CZcams doesn’t have a way to do that, but how about taking a screenshot?
I think my f80's electric fan shroud are broken. so I search ISTA and found how to replace. But I have to displace electric coolant pump hose, and bottom plate. and need special grease for does parts reconnect.
Can I pull it out without drain and easy?
+전경훈 I don’t know. My wild guess would be no
Diagrams are awesome, is this out of a manual that can be purchased?
+Michael rogers thanks! Not that I’m aware of. Got mine from the original owner that printed it.
Why do you jack the front left and drain from the front left? Wouldn't that cause fluid to be trapped in the main radiator?
+Alan Kim if that explanation didn’t make sense to you then watch this video where I change the coolant and you can see it in action: czcams.com/video/HrXuNd5cH3A/video.html
What document has these diagrams?
+DriftKr6l not sure. It came with the car
I see an oily stain around the cap of the expansion tank behind the charge air cooler on the top of the engine. I unscrewed it, and re tighten it.
Have not seen the stain/seepage since, should I order a new cap? What coolant do I use to top it off. Thanks for the video, it calmed my nerves brother 🙃
+jonathan pinkett you got it! Hope you’re a subscriber now 😉
I use the BMW coolant mixed 50/50. If you only need a little to top it off you can just use distilled water alone.
I would top off and drive like it is but check the level frequently.
@@HelpMeDIY of course I subcribe to your channel, there's waaaay too much good info not to.Keep Climbing
@@jonathanpinkett5439 Thank you!!
Do you think that it might be possible to use a venturi valve to also take out all the coolant? I mean, the point would be not just to refill the coolant but also to take it out.
What do think?
+Gilo H. That might be similar to how some dealers do it but 🤷♂️
@@HelpMeDIY 🤔 Guess I'll have to try and see what happen. Thanks a lot.
8:17 where is this pump number 9 installed?
+@m4wares958 I don’t own the car anymore so I can’t go look, sorry.
under the Aircooler for Turbolade
@@HelpMeDIY
so do they share the same coolant or are they completely separated systems?
+Anthony T completely separate
where did you find those diagrams?
When I bought the car the guy that owned it included a couple “books” he had printed out and spiral bound.
I saw the same diagrams on bmw's s55 manual, if u want i think i still have a copy PDF that i can send it to u
Ps: great video
