Link to the Tool I Use: amzn.to/3VFRgCu

Hey buddy, I don’t want to be one of those guys it goes on and on and brags but I was a level two BMW tech in downtown Houston Texas from around 2000 to 2005 and the factory BMW tool we used for refilling coolant systems works exactly like the one you’re talking about. It’s just a lot more expensive Make a long story short good video man he did a great job of explaining the steps anyone should be able t a follow this video with this tool and bleed any BMW without getting an air pocket. Good job man.

Remember both bleeding processes are fairly long so don't forget to put your car's battery on a charger with at least 12 amps as to not run down the battery. AGM batteries are not cheap and while not the same as regular ones you never want to discharge a battery below a certain limit. Great video and content as usual. Thank you for all of your hard work, Ken

Nothing like a nice video by Kern in the morning 😌

Yesss brooo got the first like and Comment. And thank you for this video, you're the best!

Grab the popcorn honey, Kern dropped another video!!!

So when pushing the coolant through the high temp circuit, you dont need to turn on the hazards or headlights?

Hi can you send me a link of the vacuum pump you used? Thanks

Same process for m340i?

Vacuum is the ONLY way. I do think it's worth a word of caution that most of the water wetter products include anti-corrosion additives and not all of them are compatible with all types of coolant and incompatible mixes can make a sludgy-like gel. For cars that aren't exposed to SUPER cold low temps, I like the idea of using a more dillute coolant mixture for a couple degrees worth of improved cooling. A 25% Propylene glycol / 75% water mix in the intercooler side will be protected from coolant slushing down to 15 deg F, and provides burst protection down to 10F. -I live in Seattle and this is MORE than enough protection for our coldest winter days and provides better cooling (5-6F as an engine coolant). More water in the mixture requires more anti-corrosion additive, though and finding one compatible with the BMW Blue coolant is the challenge. -I'm not clear on whether the BMW blue coolant for B58s is a Phosphate-free HOAT chemistry or the newest Silicated HOAT chemistry. (BMW uses both) -Silicated chemistries are NORMALLY purple, so I'm guessing that the BMW blue that's recommended for these is a phosphate-free HOAT (low silicate) formulation.

Def get the kit with the second fitting so you can bleed the filling hose first. Pull the vacuum, open the filler hose for a second, re pull the vacuum a bit, open filler valve again and it's all liquid right in

It looks like KZread won't let me link to it but I've been using the kit from ECS, ES#2712734

I’m sure I still ended up sound like a giant dish but anyway good video👍

How much hp/torque can the zf 8 speed handle

@zblazek2

I have asked MHD this question and they told me that even though 8 speed in 40i is rated for 500Nm, it can easily handle 650-700 with no issues. Doing my own research, it is good to do xHP (transmission tune) with engine tune as well, to avoid clutch slipping and removing factory torque limiters on the transmition.

Great vid! I have a 2020 M340 (only DP and intake at the moment) and consistently see IATs of around 115, even when just cruising in lower temps. Do you think there is an issue, this just feels high to me, but I could wrong. Yesterday, ambient was 45 and once I got warmed up, IAT never really dropped below 110.

Doesn't sound normal for a stock car. Check and make sure your coolant levels are topped off and there are no boost leaks.

@@kern417 Thanks for the reply, Mike from x-ph said the same thing on the forums. I check the coolant all the time and it has remained level between the high and low indicators. I guess I will schedule an appointment to have it looked at. Would you recommend an indy or a dealership? Last question, what would you think a normal IAT would be in these spring temps, just cruising?

@@Driven_G30 No change unfortunately. I’m still under warranty so I dropped it off at a BMW dealership and let them know what I was seeing. They claim everything is operating normally. I am going to take it to a local BMW shop and see what they say. Now with temperatures up in the 70s and 80s, I still see the same IAT, usually around 115 on average. Ambient temp seems to have no impact whatsoever so it does feel like its programmed to be in that range, but IDK

Have to pull the lowest hose on the radiator for the circuit you want to drain

@@kern417 ya I had to use it in a pinch and was pleasantly surprised

probably stupid question but do you want to drain all coolant out before vacuum?

Of course no B58’s in 2005😆
