Whoa. You did the entire job one-handed? You are the GOAT.
Thank you so much. Truely appreciate it.
Successful replacement with aluminum body housing complete. All operational again. The plastic O-Ring seat for the coolant channel disintegrated, causing the leak. Luckily it did not communicate with the oil channel and make salad dressing yet. Would have happened soon though if not caught in time. Thanks again for the DIY video!
This is great! 👍. 😁😁 yes, we don't want no salad dressing lol. I am happy it went smoothly.
Brother...i needed this more than you know! I've been going crazy trying to find the leak i had on my 2019 X3. Thank you
I am glad the video was helpful. You are welcome
Nice video! Thanks for bringing to everyone's attention. I've had 3 coolant leaks already on this POS plastic fitting engine. I already had to replace upper radiator hose, engine block coolant flange, and Turbo coolant line. Is there anything else on this side of the engine that could have coolant leakage? Dealer just did oil change last week, and wondering if they cracked the oil filter housing because now the leak is so bad the engine does not even have to be on.
I had my Turbo coolant return line leak at 65k miles after a long road trip on my 19 X3 Sdrive30i. What car and mileage is it at? I’m very nervous for more leaks as I’ve never had a car leak at such low miles. I also live in Texas so climate is very hot but I’ve heard people have more leaks in colder climates.
That is so unfortunate. And yes, there is a coolant hose just above the oil cooler housing and right below the intake manifold you may need to check that out to make sure it is not leaking.
@@RKSAINT The leaks are so common in the same spots. I think this should have been a recall.
Awesome video, very well done and explained. Thank you!
Thank you. I appreciate that 🙏
Is the same process for the x3 2020?
Yes, it is the same.
Oh, can the oil filter housing be accessed without removing transmission cooler?
No. It cannot. One of the bolts for the oil cooler is blocked by the transmission cooler housing
@@all-about-cars-basics Was thinking if I disconnect the coolant lines on the Trans cooler and remove the mounting bolts but leave the the transmission lines connected, I could move it just enough to access that hidden bolt.
@@docwong2020 I know. They made it in such a way that you have to remove the transmission cooler for no reason. It is so unfortunate.
Ok successful repair done! I was able to disconnect only the coolant lines to the transmission cooler and mobilize it enough to access the oil cooler housing bolts. Didn't have to mess with any transmission fluid.
Thanks!
Thank you. I appreciate that 🙏
Great video, wish I had seen it before I paid $3000 to get mine replaced about 7 months ago!
Dang! that is so unfortunate. Anyways, it can still be of help in the future. Thank you for taking your time to watch the video and leaving a comment, I appreciate that.
For this leak, does the leakage under the suv come around the engine oil reservoir wrap? How to determine if the leak is from here?
Yes, it usually comes around the oil cooler housing area. But to be certain, do some inspection by looking at the area after removing the cover below it.
@@all-about-cars-basicsi removed the oil cooler but found it was intact.. any idea what can be broken to cause coolant dripping above?
@@NickRRR-x9v At times coolant leaks play hard to get. For that case that you are not certain where it is coming out from, I would suggest you do either of these two options, first if you have access to cooling system pressure test kit then you can perform a pressure test and any part of your cooling system that has a leak will start leaking and you can identify it easily. Option two is when you do not have access to a pressure test kit, what you do is you remove all the covers below the car and let the car run for a few minutes till it builds up pressure. At that point when the pressure is in the cooling system the part with a leak will start leaking and you can just identify it easily. Good luck and let me know how it goes.
@@all-about-cars-basicsthanks. I do have pressure tester. When I tested I was only able to see there was leak from oil cooler. Maybe the leak was above it but I wasn’t able to see. Now the issue is I already removed oil cooler and transmission cooler. Is there a way I can still pressure test without connecting them back?
@@NickRRR-x9v I don't think it is possible to pressure test when the oil cooler is out. Because the pressure you need will be alot. What I would suggest is to install a new seal for the oil cooler and then install them back and I wish you had access to a mechanics mirror (it is like $4 at harbor freight) and then use it to look around the area when you do pressure testing. The Mechanics mirror will offer you alot of flexibility to see into places that would be hard to see. My guess is that (I may be wrong) once you install the oil cooler housing seal the leak will go away. Let me know how it goes.
Job well done with the video sir. Have you tried removing the intake for this repair?
Thank you. When you say remove the intake for this repair, do you mean the oil cooler housing repair?
@@all-about-cars-basics removing the intake instead of the ECU/DME connections to get access for the oil cooler housing repair. I have an x3 as well and I’ve been watching videos on this repair. Trying to prepare myself mentally and physically 😃. Mechanic shop these days will charge thousands just for this repair 🤦♂️. Appreciate your feedback sir.
@@Joseph5394 Indeed the repair cost a lot. Yes, you can remove the intake to remove it but to me personally I find it too much work and at the end of the day you may end up buying intake manifold seals and with BMW putting too many brittle plastic hoses on the engine intake area makes me avoid that path
@@Joseph5394Just checking to see if you were able to get your X3 OFH replaced by yourself? I have a 2019 X3 with 70k miles and I’m scared it’ll start leaking so I want to upgrade to an aluminum one.
@@RKSAINT hello! My car is still going strong. No leaks yet 🙏
any directions on bleed procedure? Everything I'm finding on the interwebs isn't clear except for use a vacuum fill. What happened to using the electric wp to purge the system?
It is true the internet is flooded with all kinds of information, that most times won't be that clear. Concerning the bleeding procedure using Electric WP. Follow these simple steps (I think I should do a video on this)
1. You turn your car ignition on (Don't start it)
2. Turn Cabin temperature all the way to max heat
3. Put the fan speed on the lowest speed
4. Press and hold gas pedal for 10 seconds
5. You should hear the electric water pump kick in 6. Open your coolant reservoir cap and see the coolant stream.
When you do that, it will bleed the system. Good luck and let me know how it goes.
@all-about-cars-basics yes.....that is what understood and tried as well. It just didn't work on this car unfortunately. I have bleed it by running the car with the cap off. This seems to have worked as the car will not go over the normal temp.

@@twtcadwere you able to do the bleed procedure? I had the same issue on my 2019 X3 and you actually have to turn the engine on after you’ve done turned on the heat and lights. That’s how it worked for me and the engine stays in a high rpm to let the system bleed properly.
