I'm a novice at car repairs, let alone BMWs but this video helped me get this repair done successfully. If you have this problem with your G30 this is the video for you. Thank you for posting!
Thank you for the video my friend any idea why the tank container over fill like that is because the container have this issues or is the water pump is damage?
What is the name of the line you replaced that connects to the front of the expansion tank and top of the radiator? The one you referred to as fragile. Mine was really brittle and broke and now I need to replace it.
Very helpful video, i have one question. The BMW manual says you should fill the system with vacuum on the B58 engine. They say "filling without the vacuum filler device is not permitted" but my question is, is that really necessary?
mine just started leaking and i thought it was coming from the reservoir hose underneath but now that I saw this I'm going to take my front wheel off and see if its actually leaking from the reservoir itself.
Same here, same exact thing I have to take the wheel off and look under there because if it the tank then easy fix. And I might as well change the oring inside the hose for peace of mind. It’s just a pain in the ass why they can’t just make this tank a little more durable.
You mentioned that you replaced one of the tubes with a hose. Is there a specific hose? When I look up online for parts the only option I see is the hard tube replacement, that you say is brittle and can break when changing out the reservoir tanks.
That's actually a very good question! When you order the part number they will send you the revised version which is different from what the pictures are showing yet it will still work perfectly fine with your car! Since it's just from a newer yea.
Have you done a coolant flush on the car? I looked at the technical manual and it stated you would need to use a pump and pressurize it. Other guys have done it's like a drain and fill, wondering if it's the same here
Good video. Looks like a new expansion tank doesn't have a vent screw. Maybe that was the leak issue. Where did you had a leak on your old tank? Thanks
Do you know the part number for that top front gen II expansion tank hose you previously replaced? Mine just started leaking. I replaced my large tank about 4 months ago. The side seam of the tank was leaking. No problems since, until this hose. It leaks at the connection to the tank.
Does this apply for the G30 530i models as well? I might have to check under the wheel well to check for any leaks as I noticed a small change in the coolant level in the main tank.
Thanks a lot for the video. I have a late 2017 G31. Looks fine at the moment, don’t see any sign of leaks. Do I still go ahead and replace the coolant tanks as a preventive measure? Thanks
@@FullBoltOnGarage the smal tank never moved coolan wise.. I will buy and copy paste your work 😁 i would take it to mechanic but there is none good that i know it would treat my car how i would :/ Thanks man for this video keep up good work
Can you explain what is the difference between the gen 1 and gen 2 tanks? Mine just went out a few days ago (gen 1). Maybe the gen 2 tanks aren’t as susceptible to leaking?

Great video! Thanks so much. Just changed mine without any issues.
Is this pretty much the same for b48 f30?

How did you bleed it for airlocks?

Have you got a video of the hose change
Do you need to replace the caps as well?
Thanks for the video. Will do it on my G12. Glad they also lowered the price on that website 😅
Even better 😂😂
Thank you well explained DIY. 👍👍👍
Glad it was helpful!
Whats the part number of that fragile hose

@@FullBoltOnGarage awesome, thanks for the quick reply!
Thanks. very easy!

Why not siphon out the coolant before you disconnect the hoses?
Good video. Looks like a new expansion tank doesn't have a vent screw. Maybe that was the leak issue. Where did you had a leak on your old tank? Thanks
From the bottom it seemed but it's hard to tell without a proper bleed procedure!
@@FullBoltOnGarageis the bleed screw on the reservoir or the expansion tank?
Whats the line you replaced at 1:17 ?? Need a gen2 one as well think i put a hole in mine smh

How much coolant did you loose? Im planning on just doing the main tank. Thanks
Do you have to replace both tanks if just the larger one is leaking? Does the old small tank hook up the same to the new larger tank?
No you don't need to. I changed the little one first a peace of mind
@@FullBoltOnGarage thanks!
Whats the hose you got that rubber
Do you still smell coolant after some of it spilling in the engine bay while you were replacing it?
We’re the first hose connect to
does the new tank come with a new coolant level sensor already inside?
Yes they come pre installed from factory!
Excellent video 👍👍
Hey! I appreciate the kind words my friend 🙏✌️

did you find the answer to this question
Yes
Great video. Thank you
Absolutely my friend!!!!
Hi Brother i hVe coolant leak under some where thr coolant tank, could be thr tank or the pipe? And you have to channge small tank same time?
Hey brother! It's most likely the bigger tank. You can change just one but it's best to change both as they are revised!
@@FullBoltOnGarage the smal tank never moved coolan wise.. I will buy and copy paste your work 😁 i would take it to mechanic but there is none good that i know it would treat my car how i would :/ Thanks man for this video keep up good work
Great video 👍🏾
Why did you have to replace it? On my old Bmw its over 40 years old and i did never had to replace it
Luck of the draw? Lol
They said the new bmw with B58 engine have issues with coolant tank and seal … i have a 640i with B58 and 35000miles , everything still good …
Can you explain what is the difference between the gen 1 and gen 2 tanks? Mine just went out a few days ago (gen 1). Maybe the gen 2 tanks aren’t as susceptible to leaking?
The thickness and the seal compound used to hold the top half together!
They now have it built without a bleed screw. No idea how it works as I haven’t bought / installed yet.
Great video🙂
Could I add water to check where my leak is coming from ?
What the part number for the upper radiator hose at time 1:20
great video really
Thank you my friend!! It's very appreciated
question : you don't need to mix coolant with distilled water ?
I did the mix off camera. Totally forgot to film it. Yes 50/50. Mixed back into the system!
What is the part number of the hose attached to the tank?
The one you replaced to the 2nd gen
Is the big tank compatible with old small tank? My big tank started leaking at the sensor or tube plug near sensor. Not sure where exactly.
They are 2 different circuits of coolant
@@Cmatt1299 so you don’t need to replace both if only one is leaking?
@shannonjamieson2873 On the bmw's with B58 engine? No.
Do you put same liquor in both tanks ???
Yessir
@@FullBoltOnGarage thanks 50/50mix it with water right?
Yessir! With distilled water
Thanks so much very helpfull video
