  • The B58 has a tendency to use a little coolant. I show you how to keep on top of it, and what the correct level should be.

    For starters you should do a wipe down of your engine bay EVERY time you wash your car. And I hope you hand wash it yourself and don't use an automatic swirl maker wash. If you do this you will never need to deep clean your engine and will notice issues and be able to prevent them from becoming a major problem.
    The cap is usually the issue with the B58.. Replacing it tends to fix the the problem.. Just make SURE to wipe down the white residue or else the new cap won't have a tight seal and you will still have the same issue. Also do note that the cap will be harder to unscrew when the engine is HOT. This does not mean the cap is bad, it is by design in order to make sure hot, pressurized coolant does not explode in your face. If the cap is tough to remove when the engine is cold than you got either a bad seal (get new cap) or there is a lot of white gunk (dry coolant) developed around the cap. Start by cleaning the cap and the tank. Check again in about 2 to 3 weeks (around the time of your next wash) if you have the same problem then replace the cap and make sure clean the area around tank well.
    50/50 mix means coolant and DISTILLED water.. DO NOT use tap. The minerals in tap water can damage your cooling system.

    I measured long term and came to about 1 Liter for about 20.000 Km. Normal, just like oil consumption is normal as well. Coolant has a low evaporation rate, never the less it does evaporate. People think the system is closed, but it is not. The system is pressurized, but there are temperature-pressure spikes and the related vapor is being vented via the built-in valve in the cap.

    I had the same thing happen. No much residues like your car. But had to top it up with BMW orginal coolant with a distilled water 50/50 mix. Now I check schedule a check every end off month. I noticed not very to no loss. But in a 3 month's time. There is a loss about roughly 50ml give or take.

      Actually that's wrong and the most terrible advice you can give with an engine made out of aluminium and/or magnesium.. Distilled water eats through aluminium/magnesium because it has no minerals itself, it kind of binds to the minerals in the engines. That's why you DON'T use it with these engines. The B58 is an aluminium engine, diesels or many other petrol engines aren't, there you can go for distilled water.

    Hi Reg, Thanks for the video. I only heard about this issue a month or so ago and hence checked and my main coolant tank had lost about the same as yours after 3 years and 8000 miles so i just topped up with BMW coolant at 50-50 mix. I was told by BMW to also check the smaller tank as thats for the intercooler i believe and should be checked too as this has the same yellow min/max value. Mine was ok in the smaller tank. I also think its the same coolant mix but just thought id mention / check to see if you checked that too or anyone else has?. Thanks again. Drive safe, stay safe.

    In B48 is the same. However if your level goes down the car warns you thanks to a special sensor. My coolant level also tends to go down on its own and I check it often (once a month) to avoid the risk of being far from home with the low fluid warning. The next time I leave it in BMW for a service I have it checked because I don't think it's normal.

    Love all the B58 huggers making excuses...also has a track record of oil consumption

      No oil consumption issues on B58’s. Mine hasn’t used a drop. The coolant loss, is clearly down to the cap.

    The car will notify you if the level drops below an adequate level

      Yup, don’t want it to get to that point though, so best to check once every few months just to be safe.

      ONLY for the main coolant tank.. The smaller tank (intercooler) will not give you a notification but there is rarely an issue with the cap for the smaller tank.

    Mate your cap is definitely leaking look at all the white residue around the bottle neck, there is a problem with the seals on the cap BMW revised the cap in 2019. Mine was about an inch below minimum when I checked it so I went and bought a new cap from BMW for £17. No probs since 👍🏻
