New Coolant Reservoir from 1AAuto.com 1aau.to/ia/1AROB00342
Your vehicle is equipped with a tank containing extra coolant, and space for the coolant to overflow to when the system gets hot. A cracked or broken tank could slowly drain your vehicle of much needed fluid. A dirty tank could send debris into the system, clogging it. Watch to learn how to install a direct fit coolant reservoir or overflow tank from TRQ in your 2004-2008 BMW X3.

What are you using to lube o rings?
You don't have to take the fan out. Great video
Hey wanted to say thanks for making this video! My sister and I were able to change my expansion tank and thermostat because this video is so thorough. I’ve never worked on cars before and this made me so proud! So thanks! I appreciate that you shared this!
Nice job! Was your ex tank leaking? If so, what symptoms was your x3 getting? Trying to figure mine out.
I always replace the thermostat at the bottom of the tank. I have had them break while removing the tank so it will delay you while you get the part of it does.
This video save me 570 dollars thank you so much
+italo iozzelli Thanks for watching our video, we are glad it helped and saved you that much! 1aau.to/m/Shop-TRQ
Thanks, it’s really helpful.
Worked like a charm although the intake is a bit different on the 2004 X3
All the rest was the same. Thanks for your video.
Great vid, did mine, 1” crack up side just above the side outlet that leaked under pressure only, old tank wouldn’t pull up after clip release but bracket eventually unclipped from rad shield so I could get to bottom hose to gently pry off, refitted all Ok too. Noted my top hose small pipe-connector had some inner lip erosion preventing o ring sealing properly and as o rings had flattened too I ordered a new top hose assembly to complete the job along with flush and new anti freeze. Saved me loads, thank you, good job 👍 subscribed 😎
+Steven Retro Thanks for watching our video! 1aau.to/m/Shop-TRQ
Thanks brother without this vid I would still be struggling to get that damn thing out
thank you for the great video
That was a great video. It was very thorough and simple to understand. Thank you! I am subscribing to you.
Note that this is through the 2010 E83s, at least in the U.S. For 2006-10, the engine is the N52, with an electric pump, rather than the earlier M54 with mechanical. For the N52 there is a special bleed procedure that must be done before starting the engine. Search online for instructions.
I would have left the snorkel off to check for leaks, until full/hot. And replaced that MAF with the cracked out connection. But a good video!
great video helped me out
I think i forgot an important step replacing mine. i didnt remove that giant clip at the bottom before removing the tank. everything came out together and i swapped it over to the new tank
Thank you!
Great video! Hands down one of the best step by steps I’ve seen on youtube. Thanks man extremely helpful!!
Thank you
Ive been trying to remove the radiator tank same way he did ... i removed all the hoses attached to ti and yet it wont budged
Hi, thanks for the video, it helped me a lot to replace the tank myself. After I replaced it I realized that I have to do this again to replace the thermostat which I didnt know how it look like and I remember it was broken, it still works, but it was cracked, so I am now waiting for the new part. I just have a question about the coolant (liquid), the fist time I did not drain the coolant completely and I just filled it up after I finish. what happens if I dont drain the liquid before taking out the tank again?
You’ll get air inside the system you need to drain the old fluid and wash the system is super easy
Why did you need to disconnect t the battery?
Great video. Thanks for sharing. What do you use for lubricating the o-rings? Is that silicone grease?
I have the same question. and can I use WD40?
Non petrolium product, silcone grease
What are you using to lubricate the o-rings grease oil, any seize?
what kind or anti-seize did you put on the o-rings in the plastic fitting?
Just replaced mine 2006 manual trans X3 3.0I I broke the plastic mounting bracket trying to wiggle the tank out thinking it was the O rings at the bottom hose holding it on. Anywhere I can buy just the plastic mount? The tank is zip tied for now
Hello, Is it safe to put a wool blanket over your engine in your battery in cold weather?
Hi, in 2008 bmw x3 i see tge same steam coming out but the temp gauage is normal and not rising, i dont see any temperature gauge pin moving towards red, also the radiator fan doesnt turn on while steam is coming, tried with bmw standard bleed procedure i dont see any coolant coming to reservoir tank, also i see the engine oil i coulnt see any milk color or coolant mixed with the engine oil nor i see any leak outside . any suggestions
What is the name of the lubrication for the o rings and housing?
Sorry -- 2007 to 2010 had the N52. 2006 still had the M54 with mechanical pump, unless an N52 slipped through late in the model year?
My friend, I disconnected the coolant level sensor plug, but it still shows me check coolant level, what is the solution?
What was the reason for changing the reservoir tank?
can I use WD40 to lubricate the bottom 2 orings? I can not get the expansion tank to seal at the bottom. ordered multiple of everything already with the same result
recommend just using a little Vaseline on rubber o-rings
WD40 is like pentraiting oil, so bad idea.
I missed the radiator coming out??
😅
