    One thing to add... the smaller reservoir is for your intercooler. The intercooler is built into the intake manifold on the B58. Another loss of coolant can be your intercooler leaking and sucking coolant in with air. This will also cause white smoke issue.

      How often does the ext. engine coolant need to be refilled?
      I got the low coolant warning message, so I filled it to the maximum mark, two days later I take my car for an oil change to a local shop and they checked the antifreeze plus the external engine coolant (is this a separate reservoir?) but no leaks or problems reported.
      Please answer this if you can, my 2017 X3 needs around 300mL of coolant every 6-12 months it's @66K bought it used from the dealer 4 years ago @15K. How normal is that?

    • @kern417
      @kern417  3 роки тому +2

      Yes there are other potential issues but overall it is reliable. There aren't any common catastrophic failures that cause failures like engines, turbos, etc. They're also more common on early models (2016s) but you can see things like this are a quick fix if it happens to you.

After driving for a bit, my JB4 tells me my IAT is above 100 and the sensor usually turns off. I’m guessing that means the whole thing needs to be replaced.

  • @johnbolton9968
    @johnbolton9968 3 роки тому +2

    Thanks much for this. The main coolant reservoir on my 340i is just at the min right now and I had just chalked it up to the extreme cold we had here in the Midwest since there was no warning in iDrive. My E46 330i seemed overly sensitive to coolant level, so I expected a warning if anything was amiss. I've also noticed little spots on and near the reservior that don't belong, so I highly suspect that it's the coolant cap.

    • @kern417
      @kern417  3 роки тому +2

      It could be the reservoir as well. That was leaking on my X5. A pressure test will confirm and some dealers will do it for free/cheap if you don't have the pressure tester.

      @@kern417 Hey...just wanted to say big thanks for pointing this out. I replaced the cap on my main coolant reservoir, topped it off and it hasn't dropped a bit since.
      Over this past weekend, I replaced the stock airbox with a CTS Turbo Intake (despite all the recommendations that the stock airbox flows fine) and I really like the sound. I was pulling 4th gear to redline yesterday morning and threw a 20E120 - Crankcase Ventilation Host disconnected code though. I checked all the fitment, tightened down the hose clamps a bit more and it hasn't come back yet. I haven't had a chance to pull 4th to redline again however. I got a couple questions if you have a chance to answer:
      - Does the crankcase vent cycle back into the turbo inlet?
      - Is there something I could log to get more insight on what is causing the code?
      - Is installing a catch can worth it on these engines? I've heard the PCV system is adequate to where an OCC isn't really necessary on stock turbo....thoughts?
      On my B5 S4, the OCC was an absolute must because that PCV system was junk from the factory.
      Thanks for all the great content.

      @kern417  3 роки тому +1

      Thanks man. I also have a video on the code you got if you check my channel. It's a very common code to get with an aftermarket intake.
      The crankcase vent has to recirculate before the turbo, but our cars do not have a tendency of pushing a lot of oil. So for the most part a catch can is not needed.

    Aye bro thanks for the video. My main expansion tank is fine. (Blue coolant and correct level) but the smaller coolant tank is over filled with a clear liquid. (Smells like coolant but it’s not blue). So far I’ve never gotten any warning lights and the operating temperature has been normal and consistent. If you’ve seen or heard of this before I’d really appreciate some advice on if I should keep running it or take action. (Not under warranty btw)

    • @kern417

    Another superb informative and well explained video. As said above,the smaller reservoir is for the large front intercooler (that you upgraded in a previous video), air to water intercooler in the inlet manifold and to the turbo itself.
    I have a 2017 M140i (UK) and in 18 months of ownership I’ve had to top-up the larger engine side coolant reservoir with approximately a quart full of distilled water,tiny amounts at a time as I check it regularly.
    My thought is evaporation via a faulty reservoir cap.
    One question though- to refit my cap (stone cold) takes extreme effort,I certainly can’t just spin it on until the locking point like yours? (The threads are clean and no tell tail sign of leakage around the reservoir top🤷🏼‍♂️)

    • @kern417
      @kern417  3 роки тому

      The small reservoir is for the intercooler system only. The turbo and engine run off of the larger reservoir. Like I mentioned in the video, the small reservoir doesn't have a level sensor so it doesn't throw an error message for low coolant. That's why it's not included in this video.
      You may have a faulty cap If it's difficult to put on with the threads clean. There shouldn't be any excessive resistance.

    • @anthonyh958
      @anthonyh958 3 роки тому +1

      @@kern417 thanks kern,I was told the larger reservoir was engine and smaller one the turbo side of things. I’ve no doubt you are correct though,would make more sense to use the larger volume of coolant to help in cooling the turbo itself and keeping the other circuit to concentrate on IAT 👍.
      As for the reservoir cap on my m140 it appears a known issue here in the UK. Some have even been applying a very thin film of lube spray around the last few threads which I won’t be doing.
      I’ll take the issue up with BMW themselves.

    Thank you for this excellent video, i have a 440i , i had the problem of lack of power you are talking about, then the fan that starts every time i stop idling. I went to bmw, they changed the water radiator. Now when my car reaches ist normal operating temperature, my fan starts at low speed, then it won't shut off again unless i turn off the engine. if i let cool for 1 hour then i restart it then the fan also starts. After 1 hour /2 hours of use, the fan switches to an even higher speed when stopped, the engine speed rises to 750rpm instead of the usual 650rpm. I had never seen this before even in high heat, i sspecify that this is seen without the air conditioner of. i don't think it's normal. Can you help me about this. excuse me for my english

    When my car was under warranty, the dealership did all these steps and said you have no leaks, it is normal for this engine to lose a little coolant. The nerve of these people. They should have changed the cap under warranty if all else failed. I check my coolant every so often after my initial warning and i too see a little white crust around the cap. I suspect it is my culprit and because it's cheap, I'll start with replacing the cap (based on the dealer saying no leaks exist, pretty new car still)

    Is it normal for the coolant in the big coolant tank to turn clear? It used to be blue/green but now it turned clear. Should I be worried? I had this issue about a 1-2 years ago and I thought the previous owner put the wrong coolant since it was a yellow/clear color, so I took it to bmw to have the coolant flushed and refilled but now it’s back and this time it’s more clear than yellow. The smaller coolant tank is the right color it’s just the big tank that’s giving me a problem. Could it be something I have to be worried about? The temp doesn’t get high just under 250°. I’m not sure if this helps but It’s a 17 340 with 34k miles stage 2. I’d appreciate the feed back!
