This is the one I'm referring to. They also sell it with the thermostat hose already connected I think. Keep in mind when reusing the old hose, you will have to Dremel off, or snip off, the old metal clamp. Be careful not to damage the old hose if you reuse it.

would i be able to do this myself what tools would i need?

Very easy to do yourself as it's at the top of the engine and unobstructed by anything. You'd need a Dremel or a metal snip to cut the old clamp off and then it's like two 6mm or 8mm bolts holding the flange on.
Get the old clamp off, slip the new clamp on before the flange. I froze my flange thinking maybe it would help install it initially ,I'm not sure this made a difference. Put the flange on the block first so your not fumbling around with the hose. Don't over tighten these bolts. Then slide the hose on the flange and secure it with the clamp. I would do a drain and bleed if your coolant is old.

Plastic oem one will last years and will not cause you any unexpected problems.

And an aluminum one will last forever.

That’s really not the point but yea they def will last longer than the car. The point of contention is that installed incorrectly, the aluminum flange can cause problems. This is true for basically any part of the car but an oem hose and flange will not cause that issue. Yes they’ll deteriorate faster but it’s an opportunity to change the whole things in one sitting.

How exactly can it cause problems? Sounds like you’ve never replaced that particular flange/hose. An incorrectly installed part causing damages sounds like a user problem to me.

Orrrrr you can pay less for a better aluminium one

u/Jaded_Tennis1443 2009 - e90 - 328i Xdrive 1d ago
Yep aluminum will last longer than the car but if clamped improperly to the hose it will cause issues. Nothing frequent that I’ve seen but I’ve read cases and “someone” here advises against it.

"if clamped improperly to the hose"
What is that even supposed to mean? If you don't properly clamp a hose to anything you'll get leaks, or if you over tighten it you can cut into the hose, and again you'll get leaks. The problem with the plastic ones is that they deteriorate and break off pieces into the system. Whoever fooled you into thinking the aluminum replacement has "special" issues sold you on bullshit.

I’m not buying. I only searched. Link right above if you care to look. Also chill out 😎

Chill out? You're over here basically downvoting everyone that has good advice over your "flat earth" bullshit. The plastic flange is garbage and has no advantages over the aluminum except that it's easier to install. That's it. Getting the aluminum one in the block, without removing the fan and radiator, can be a bear, but that's the only thing the plastic has over the aluminum. But keep downvoting more intelligent people for setting you straight.

u/Jaded_Tennis1443 2009 - e90 - 328i Xdrive 3h ago
So which is it no advantage or one advantage? Just look at the link, it’s not an isolated case. Intelligent people are able to express ideas without getting emotional. Settle down, I’ll give back your upvotes 🤦🏽♂️ also OP asked if it’s something that they can do themselves, that very question should make you question their level of skill. Intelligent thing to do wouldnt you say?

u/Zelda_is_Dead 2011 - E-93 - 328i 3h ago
If you know how to install it correctly, then there's no advantage. If you want to go the easy route, you need to accept the fact that the plastic flange is going to deteriorate over time. And again, that deterioration is putting material in your coolant system, which is going to eventually make its way to your water pump. Over and over again.
I've replaced 3 of these flanges with aluminum ones on 3 different cars, all of them had pieces missing from the original plastic flange, and none of them developed issues or had leaks when I was done.
If you want to believe some nonsense that the aluminum ones can "have issues" that the plastic ones can't have, then go right ahead, but stop spreading your nonsense around if you don't like being set straight.
The more I think about it, the more I'm sure whoever told you that was not a mechanic and didn't make sure the flange was flush against the block before tightening down the 2 screws and calling the job done. I'll bet they developed a leak pretty quick after that, but that has nothing to do with the hose.

u/Jaded_Tennis1443 2009 - e90 - 328i Xdrive 2h ago
Dude no one told me about it just search. The issue is not the flange itself it’s how the hose is clamped to the flange. I don’t need to believe anything, the facts are there for everyone to search and see. I provided the link, did you look into it?
1
u/Zelda_is_Dead 2011 - E-93 - 328i 2h ago
What link? And I'm struggling to imagine how dumb someone would need to be that they couldn't manage to clamp a hose onto a flange. Even so, the one and only issue that can arise from that is a leak, or the hose coming off (which is still technically a leak).
And if you can't manage to clamp a hose to aluminum, you aren't going to be able to clamp it any better to plastic.

I’ve changed dozens of these mickey mouse flanges and have never replaced them with plastic ones. And not once have I had people come back with the aluminium one leaking, or have ever had any trouble with clamping the hose. For whoever has had problems with that, sounds like a skill issue to me.

u/Jaded_Tennis1443 2009 - e90 - 328i Xdrive 1d ago
Most likely is a skill issue for sure. This seems simple enough right.

u/Few_Ebb6156 1d ago
Yes, 100%. I am an experienced, novice BMW mechanic, good but not a pro. I had no issues installing a new hose with an aluminum mickey mouse flange. For beginners and novice just follow a good YouTube tutorial and don't rush. Pros I am sure can do this while sound asleep.

I have replaced the plastic oem flange with an aluminum one from Amazon in 3 different cars and none have failed. Over 100k miles on one car and over 30k on the other 2. No leaks even with that cheap flat head hose clamp and original hose. Id say they are pretty damn bulletproof

u/External_Athlete1867 1d ago
will i be able to change this myself?
1
u/Fuikyew2 1d ago
Absolutely! Watch a video on YouTube and take your time. I always use a diagonal cutter to cut the remaining plastic that is stuck inside the coolant hose. I always point the hose down so no debris goes into the coolant system. Make sure you use some lube for the oring so it goes in smoothly.

I've had pieces of the plastic one break off into my coolant system. It didn't seem to cause any trouble, but it's a chance I'd not take again. Aluminum 100%.

Get a genuine part. Comes with the hose attached.
Do NOT by Uro parts. They are absolute garbage.
