Thank you. You can't imagine how your videos has given lot of us (me) the confidence to work on our cars and be able to save a ton of money. Thanks again.
Well said! He is the reason why i'm dared to buy an E46. Such a great cars!
@@user-ym5mw8ft6d Good day Sir
My BMW X3 e83 is leaking I changed the expansion tank twice but it does not stop leaking,Please help
Chasing one coolant leak after the other is what made me give up on BMW's all together, you have more patience than me..
Excellent video, you didn't talk too much or go too slow and fantastic camera work, very clear and helpful. Thanks man.
that's like the easiest water pump I've ever seen thanks 4 sharing
One of the best car videos I’ve seen. Just what I needed.
Great walk through of the repair and love the introduction of the coolant pressure device. Once again, time is money and why I only use oe or genuine BMW parts. You did everything right, but the cheaper parts are a risk and put you at risk. Hopefully the water pump gives you at least a couple of years. Thanks for the transparency and authenticity of your videos. Please keep them coming.
I’ve just done the expansion tank on my X3 and mine has the same leak around the top of the expansion tank . Great video.....
50s Kid so glad I took the tune ti watch your video ask we have a slow water leak the leaks more on some days then other to the point its leaking less I’m hoping it fixes it self. The leak being so small has been hard to pin point where it is coming from, you pointed out that the little hose was the cause of the Problem and I think you just found my leak I will start with replacing the Upper hose before I go and replace the resort or tank like I had plan to do. The car has over 150,000 miles and like you we don’t see it as a wise investment to buy OE parts at 3 or 4 times the cost of OEM parts. Keep making these videos for us Shade Tree Concrete Sweeping Mechanics I’ve been able to keep my X3 out of the shops watching you Fix things. Thanks and happy 2021.
Terrific DIY video, thanks for your attention to detail. Just discovered my '05 X3's water pump is failing and leaking - I can see the pulley actually wobbling while it's running... Pretty sure I can tackle this one - it appears to be a great deal easier to replace than the water pump my '92 Mercedes 190E 2.6 - that was a nightmare - had to pretty much remove the entire front end to get access, and even then I just barely could get to the bolts. Thanks again!
Nice work. I did this on my 04’ Z4 last year. I need to do this soon on my 06’ X3.
Hey 50, thanks for another great video. I had this EXACT same problem with this same Rein hose on my e46, it bugged me for weeks. I patched it up with some gasket maker at first but didn't work too well so i bit the bullet and bought the OEM hose, problem solved. I guess Rein dropped the ball at some point for these, definitely one of those times when only OEM will do. Thanks again!
Hi there and again thx for your efforts!
I got a helpful information for those of your audience still with a visco-elastic clutch between the coolant pump and the fan: the thread that connects them is left-handed!
Thanks, i always appreciate your videos
Been watching your videos for a while and it’s only because of them that I can work on my E46 myself. Thank you (p.s it’s nice of you to give the car to your ‘sister’).
Had exact same upper hose small o-ring leak on my E46, o-ring size is ID 16mm OD 22mm, 3mm thick o-ring, problem solved.
Jason, great fan of your content. Since you like to research your problems other than just fix them, you need to look into BMWs Achilles heel, its thermostat. The reason why all BMWs leak, plastic deteriorates, components fail is because the engine runs so hot. Thats the reason most other cars dont have the same failures because they run cooler. BMW thermostat temperature range are too high. Figure out how to lower temp and all BMW problems gone. Cooler engine better for high speed. The only time you need it hotter is in city to help with mpg but thats negligent compared to repair costs.
Another great video 50's kid....
As always! He should borrow his friends' cars to repair and filming the procedure , his knowledge and professionalism could help to a lot more people, not just us BMW owners.
He deserves much more subscribers, he is one of the best youtubers.
Been using gates hoses off amazon, even did them on a e83, going to get me one of those testers too
+Nathan's DIY Garage it’s such a helpful tool, man. Astro makes a slightly more expensive one that also has a vacuum filler
Thank you...Nice step by step
Don't worry about registration, they have conditioned us waaayyy past the point of feeling free haha thanks for the info
great video mine just went out but not the duralast pump 😭😭 but i understand i'm kinda in the same situation where i may just get the duralast pump to hold me over until i get an oem one.
that duralast water pump is actually a GMB unit (it says it on the pump too) thats cool. good quality pump.
thank you for your video clip I like it by the way what is Milwaukee drill ?
Possibly the expansion tank was responsible for the upper hose joint leak. Perhaps was changed for an aftermarket part that's not toleranced correctly during design / manufacture.
I purchased an upper rad hose for an E9x BMW, was also Rein brand. Oring did not seal at all had to improvise with a different oring.
Another informative video. Thank you!
I have encountered the same issues with aftermarket hoses and espescially the expansion tanks. I understand your reasons on this build but I will reiterate your point that OE is the way to go on these critical parts.
The issue I always encounter is the expansion tank to bottom bracket mount almost always leaks if one part is oe and one isn't.
Yep I've had problems with the expansion tanks on the larger o-rings too.
Especially when factory pumps are only $15 more than autozone.
Just bought one for $70.
hello jason. would it be a good idea to put some dialectric grease/silicone paste on the o-rings of new hoses?
I would hope that may help with installation and seating the o-rings better.
And then i saw you do that on the water pump o-ring......
Great video
50sKid Just want to thank you for making these videos I used your video to rebuild my X3 cooling system had a leak. I could not find the leak after seeing your video showing your leak being the upper small hose on the expansion tank so I bought one and the hoses. I started by replacing the Expansion tank and upper and lower hoses it still leaked so then I went all in and replace the Water pump and Radiator then reinstalled the new expansion tank. After filling the radiator at he big lower hose on the expansion tank was leaking luckily the radiator came with 2 O-rings that turn out to be the same size for the big expansion tank hose that attaches to the expansion tank Mounting bracket, leak stopped now were good to go.
The only hose I did not replace was the one that goes from the expansion tank to the top of the back of the engine as I cant figure out get to it. Do you have a video on how this hose can be replaced and what is the name of this hose so I can order one. I think it goes to the heater core. Many thanks Ralph C
Great vid, thx
I’m pretty sure my thermostat is faulty. Overheating when idling, cranking the heater up lowers the temperature. It sat for a couple months. Going to check levels, bleed the system, and hopefully have a fix. I’m actually kind of excited to replace the water pump. Mine works fines, but it’ll be a fun “preventative maintenance” project.
I bought a water pump online with the metal impeller instead of the factory plastic one for about $40 dollars for my 2002 bmw 330ci which has the same engine.
Miss you Jason, hope all is well!
I would like to change the hose at 11:58 on my car . Is it difficult to remove it? Can i reach the other end of that hose only by removing the air filter house?
Jason, things must be really bad if you're hoping Doorman will save the day haha. My kit has been getting a workout lately too. This time I got lucky, I had the gasket I needed in a kit lol will probably never happen again but it was nice for a change to be able to fix it on the spot and not have to spend money!
I know, I wasn't happy that was Dorman (if we've all learned anything from Eric O, it's that Dorman sucks!!) but it was my only option! Glad I didn't have to use it though.
Hey Jason, nice video, I have a question about re installing a new water pump. I understand that the water pump o ring is preventing any leaks once the water pump is installed in the water pump housing. So the questions is: In order to have a stronger seal, could I use grey RTV just in the outer flat edge of the water pump, I mean the edge that is flat and touches the flat edge of the water pump housing? if so, using an small amount of grey RTV can afect the torque specs?, as I see the two surfaces where the RTV is going to be placed are quite flat and the RTV is going to be squished out mostly. I am asking because when you change the thermostat on a e46 video you added RTV to the side of the gasket just to be sure. Could you please clarify me?
just a thought to consider. the size of an oring is snug relative to the sealing surfaces and when correct size is correctly fitted then the oring exerts tension against the surfaces it seals against.
now RTV in its uncured state ,exerts no such tension except for the adhesion of the uncured sealant. once cured however the seal is not mechanical as there is no tension in the RTV sealant so a better fix may be to make an oring out of rtv using any molding material like play dough or plasticine or let the rtv sealant cure before assembling to create the sideways tension seal in the new hard cured rubber. i hope my explanation helps and is understandable
whats the pressure rating on your expansion cap lid, is it 140 or 200?
You didn't list what type of rechargeable led light that is. What brand light is that so i can order one.
Does the 2005 X3 have an auxilary water pump or not? What are the symptoms if it's off. The aux pump is used in some of the other model and years. The bleeding process involves engaging the aux pump by turning key to #2 position and supposedly we should hear it and supposedly the water level in the surge tank should go down a little as the aux pump and heater core are filled with coolant... Please advise.
Better than an inch pound torque wrench is a deci-newton meter one (1/10 of a newton meter) I have a Snap On 1/4 inch drive unit that goes up to 20 Nm (200 on the wrench) and gives you great monitoring of low torque fasteners. I also refuse to buy gyppo aftermarket parts to prevent the exact problems you are experiencing.
Glad I’m not the only one with a leaky X3 lol
Me too. Change all hoses...rubber is old.
Hello I just experienced a heavy coolant leakage in my bmw 3x wondering how to go about this
What if pressure test done on BMW X3 and know leaks found? But leaking coolant
I have coolant leak even I swapped the whole thermostat housing, upper and lower hose and expansion tank. I see now coolant running all the way to engine oil pan underneath and dripping. My guess is it could be bad pump now. what do you all think, plz let me know?
I have an 02 325i and every time I turn my ac on my car wants to overheat please advise as to why.. It only happens with the AC. I changed my thermostat water pump and flushed the cooling system and my ac still causes my car to run hot and with the expaansion tank top off you would think I was boiling water on full blast. The coolant comes gushing out supper hot. But other than that my car runs fine with no problems
Check if fan comes on and temp sensor. If not might be head gasket
BMW TIS says coolant hose O-Rings must not be lubricated in any way.
I was just wondering if you help me with coolant warning light issue. The amber warning light comes on and off intermittently from time to time which is driving me mad. I have searched and searched for an answer but there seem to be too many variables.
My coolant level seems fine in the tank and is at the correct level. There fore there does not seem to be a leak.
I thought that maybe there was some air trapped in the system but I am unsure of how to bleed this out. Can you perhaps provide some advice for me.
oh well after a lot of searching I have resolved my problem. The amber warning light reveals a low coolant level which could, of course, could be caused by many factors such as a leak. After checking my coolant level though on many occasions the level seemed to be fine - at the maximum level.
What I now discovered though(after much frustration) is that when I ran the car with the heater at the highest level and with the filler cap off, the level dropped off quite a bit - in my case it took about 400ml of coolant to top it up. I inserted a plastic tube into my breather outlet (found this little trick on RUclips) and fed it back into the filler inlet. I topped up and waited for all the bubbles in the system to come up through the clear tube.
Job done, fault solved. No mess from spillage from breather either. If you have an intermittent amber coolant light come on then I would suggest this to be your first check. Don't check your coolant level cold, check it with the heater on max and the car running.
Many thanks to 50sKid for all your sharing.
What year is this car?
Hello how are u? I have a question what do I need to do to be able to put a m3 bmw clutch flywheel and throw out bearing in a 02 325I bmw is that all I need or do I need more stuff? Please help me
Thought the pump was electric ⚡⚡ o
Dude! You get what you paid for! I feel so offended when I hear someone saying CHINESE JUNK ... Whatelse do US making besides missiles and bombs?
let me tell you......the bmw cooling systems since 1995 are SHIT! on all cars! that "click on" system sucks bad. o and never ever use after market parts from febi/bilstein.....they never fit 100%. what ever you change on the bmw look for parts from: Hella,Bosch,Siemens, Meyle HD, and sometimes Lemförder but lemförder is well. other stuff like metzger,febi,topran etc. they do say "made in germany" but its just the sticker that is made there..... other materials lighter etc. just dont.....
ps.: iam a official bmw mechanik...well i was!
Typical over engineered German design and check on that great paint peeling on the hood.
what causes hood peeling?
