What are you using to lube o rings?

[@paulanealey7690]

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!

[@divakim206]

Nice job! Was your ex tank leaking? If so, what symptoms was your x3 getting? Trying to figure mine out.

[@octaviotavarez1]

You don't have to take the fan out. Great video

[@sreng81]

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.

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.

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 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 😎

Great video and thank you. What lubricant did you use on the bottom of the expansion tank? Many people have asked. Other people have mentioned silicone. I was hoping you could give a better answer. You used a lot on the brush 😁👍

[@The3speedautomatic]

That was a great video. It was very thorough and simple to understand. Thank you! I am subscribing to you.

[@philipwaters2554]

what kind or anti-seize did you put on the o-rings in the plastic fitting?

[@jaydee177]

Why did you need to disconnect t the battery?

[@timrunke]

What are you using to lubricate the o-rings grease oil, any seize?

[@mikesleg6844]

Great video! Hands down one of the best step by steps I’ve seen on youtube. Thanks man extremely helpful!!

[@MartinMJZboost]

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

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?

[@iozzelli1]

You’ll get air inside the system you need to drain the old fluid and wash the system is super easy

[@hellswindstaff91]

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

[@altonnash43]

What is the name of the lubrication for the o rings and housing?

[@tanopang3268]

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

[@greenstarplastomers9352]

Thanks, it’s really helpful.

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

[@silviataylor92]

Hello, Is it safe to put a wool blanket over your engine in your battery in cold weather?

[@أحمدخريبين-ق9ر]

My friend, I disconnected the coolant level sensor plug, but it still shows me check coolant level, what is the solution?

[@HemiCudaGuy]

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?

[@SirDunkzAlot]

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

[@johnathanrichardson7405]

recommend just using a little Vaseline on rubber o-rings

[@deanb1757]

WD40 is like pentraiting oil, so bad idea.

[@mithritades]

What was the reason for changing the reservoir tank?

[@jt3943]

thank you for the great video

[@allansundstroem]

Great video. Thanks for sharing. What do you use for lubricating the o-rings? Is that silicone grease?

[@SirDunkzAlot]

I have the same question. and can I use WD40?

[@deanb1757]

Non petrolium product, silcone grease

[@ridiculousnesst]

I missed the radiator coming out??
