Sound advice. Just replaced a water pipe elbow that perished. Love and behold, pipe went to extremely high pressure and needle was climbing fast. After watching this video i can admit that bleeding my system cured the problem instantly

Fill the water tank at max,(engine off) Put fans on max high temp and wait ,if needed add more coolant.If coolant is not falling anymore close watertank,open bleed screw a little so that air can come,start engine and watch bleed screw,if there is no more bubles coming youre done.But dont forget to check coolant level again to add some after bleeding.

You still have to start the engine, allow the thermostat to open, so the coolant circulates through the system. Air trapped in all the nooks and crannies can only escape when the coolant is circulating. Then have the bleeder screw cracked (meaning half open), so air can escape, and the expansion tank fluid will go down (coz the air is replaced by the coolant). Keep filling in more coolant until it wont go down anymore. I did this and the car literally took 4 liters more coolant!

Great help! Worked seamlessly on a 2004 325ci!

im on my 4th coolant tank for my e46!!! I now understand that BMW does not like China parts! The only one that clamps down correctly without a hassle is a BEHR OM TANK. I just had one, but did not bleed correctly and busted the o ring. I put the cap on too prematurely and couldnt turn car off in time before it popped the bottom. smh ...I then got desperate, bought a cheap Dorman from autozone, didnt fit correctly, lasted 1 day. DORMAN is complete trash! do not buy! only buy BEHR which is OM, or from BMW directly! all tanks are a pain on a bmw e46 honestly, but so far BEHR snaps on easiet. When my new one comes, i will follow your process to a T! this week has been hell for me! Thanks for the video! BLESS UP!!!

Thank you, this video is the best one on youtube to bleed the coolant. And forget the green coolant haters they probably don't even own BMW's and they probably don't know their crapped out 97 Hondas take blue coolant too.

Thank you for this video!!! Helped my wife’s car out immediately! Had the coolant light on. Checked and it was bone dry. Did this and worked like a charm

I read the comments on this video and laughed. You did a good job my man! Universal antifreeze is compatible with ALL engines...And for those that are arguing about what manufacturer recommends, think for a second....they engineered & designed this piece of sh*** car that always leaks & burns oil, coolant, & needs full suspension overhaul every so many miles, do you guys really think they know what coolant is best for this car? Also the only oil you should trust in a performance car is Mobil 1, not Castrol LOLZ.

You’re supposed to use blue coolant… bmw or even European coolant. Green is gonna increase the time you have to change your coolant system. E46 have really weak cooling systems. 85% of the issues with many e46 will be coolant related.

thanks guys worked for me but i used the blue European coolant

Does anyone have a source for all of the test codes like the one in this video? I've been look for a list of them for years

Thanks for this video. The same i do for my m57 engine and everithing work perfect💪🏻💪🏻💪🏻

I think on the end of the video you have to let coolant out of the reservoir so the dipstick is just above the top, you can see it on the stick inside the reservoir, rest is good i think

Surprised this worked without the car jacked. Guess it depends on the mood of the car somewhat. For me the struggle is real.

Im at 360,000 on my bmw 1999 323i never replaces engine or gasket. Been running green coolant for ever no problems.

Is it possible to bleed the cooling system without my heater blower working.my A.c unit doesnt blow air

Great advice and work......excellent.

Very good job thanks for your time 😅

Correct me if i'm wrong,but that model bmw doesn't have electric water pump,i can see the fan blade spinning,so the water pump is belt driven.and why he didn't put the fan shroud back on.

Oh god, forget this. Turn the key until the dash lights up. Hold the gas for 15 sec (this will engage the electric water pump) walk to the pressurized water pump. Open the cap, crack the bleeder valve (as in the video) and over the course of 15 min the system will cylcle if all is well with the electric pump. Add coolant as needed. This works on bmws' with an electric circulation pump (i believe all post m52 engines, not 100% on that)

For a 318i 2001 is blue Nap free coolent

Blue coolant BMW only, please make sure your coolant systems are bleed out if this is a first time diy ..... keep the 46s alive out there guys

How far can I drive my bmw if the coolent low light is on

porque que o BMW X5 de 2005 LPG falha muito guando fonciona com LPG?

Great DIY. Thanks for the major help!

Bmw makes Peak coolant now?

Good video! Thank you

excellent job

never seen it done this way. it's always worth the ignition on (but not started) while pouring... I'm having problems with mine done the way i said earlier. This should be worth the try. After getting it bubble free, did u pull the extra coolant out?

I changed my whole cooling system and I keep having leaks at my oil cooler. The coolant side keeps coming loose after I drive the car for awhile. When I fill the tank back up I’ve always filled till I seen coming out bleeder then I stop. I never waited for bubbles to stop forming 😮I’d just close up the tank, close the bleeder screw and be on my way till it started leaking again. Usually same day or the next. Is this why? Cause I’ve been bleeding wrong?

THANKS FOR YOUR VIDEO!!!

Totally worked!

Hi there, i have done everything on the video to bleed the system. During the test on the dashboard. The digits were showing up as 50 in the beginning and then went up to 80 after about 8-10 minutes. I was just wondering how i could change the digits to celsius as i believe it was showing as fahrenheit. Also it isn't coming as hot as it should be, is there any suggestions as to what it could be and what i could do? Thank you

I did the temperature test on my e46 in the morning and it was showing 50°C????

It's great, thats is possible for e46 facelift 2002 320d?

hey man will bleeding help any with a car that overheats? ive replaced thermostat and waterpump .. fan works good and there is no leaks but still overheats

You can use green or blue coolant as long as it meets BMW N 600 69.0 specs and doesn’t contain nitrite, amine and phosphate. Always mix 50/50 as that is OEM standard. An example of this is Penrite’s Green OEM Coolant Concentrate. Ofcourse don’t mix blue with green (i.e. use what’s in there), but don’t be turned off using green coolant, just do some research.

Good job ! Greetings...

Thanks for this, I have been chasing my air bubble for a while so going to use this process to finally get rid of it, as so many people claiming the right and oly procedure out there. Can I ask, once I have done this process if I take the car for a drive get it right up to max heat, can I pull over open up the bleed screw a few turns to get any extra air out and then tighten off again whilst keeping the ET cap on all the time? Is it okay to do that? Then park up let it go cold - check the level again in the ET. Can an air bubble too stubborn to get out using this process? Sorry amateur who only knwo about the outside not the inside of a car. P.S. nicely handled with the green coolant haters on here. Ultimatley there's the millions BMW spend on marketing and their of wording things is to deliberately make us fear missing out and to have to have peace of mind so we must pay their prices. Other companies just shut up and make great stuff without the added value and our cost of fancy marketing. :)

goood video

what's the purpose of turning the heater on before turning the car on ? Doesn't turning the car on then immediately turning on the heater serve the same goal ?

So when this video ends is when you put the cap on? Even though the coolant is up that high?

Hello, and for diesel engines the engine coolant is drained, or only for gasoline engines

Thank you

Solid video but wrong coolant. It has to be blue, preferably oe bmw coolant, just as cheap as any off the shelf blue coolant. So might as well stick to bmw coolant and not risk messing up ur coolant system since it wasn't designed to be used with other types of coolants

Stopped the video after I seen green coolant.

great vid. just had my radiator replaced on my 2000 320 and now theres coolant seeping from the bleeder screw. Is that an indication that it wasnt bled properly?

I seen that car at the pick a part same green coolant

Do the car have to be crank

Hi mine is a e46 m3 so how do I bleed mine no screw hole next door to my tank thanks

Hello .I just got my car back *e46 330d after replacing the steering pump. But i think they done something with the coolant tank. Now i see low coolant warning. When the engine is off i can see it has coolant inside. But when i start the engine the coolant disappearing somewhere. is it normal? But its restore back ASAP once i switched off

Have 2011 bmw750li when I first put coolant In used universal just a little to top off then I used pensostat nf am I still good

I tried this, but my E46 hose gets old in the summer and the temperature goes up to 103 degrees, what can I do to help?

Un video para poder quitar El deposito de antico gelante como lo Quito see rompio

Never heard of an electric water pump before. Only belt driven.

I think everyone should start using the new and improved BMW coolant. It is metallic blue.

This guy using the wrong coolent wtf ?!?!?!

rpm start engine on 800-900? mine stuck on 600-700

Thanks

my car does that little hesitating thing when its cold also... i thought it was just mine. nice vid ill try this in a minute. i just replaced the radiator/expansion tank, because my fan exploded when i was doing doughnuts, and took out my radiator and expansion tank... but my problem is i dont have heat even after bleeding, it worked fine before. do you have any advice? i have a 2000 328ci

Hey friend, I have 2005 325ci and only heat comes from the vents. Even at the lowest setting, blazing heat. Any ideas? Engine temp is normal

Distilled OR deionized water..

My coolant cap was barely on due I need to bleed it now, it over heats.. please help

Not all e46 have auxiliary water pump ! The 5 series hall have cus minimum 2 way climate control! The e46 only one ! If u see under intake boot that heater core valve

Do I have to do this even though I'm not replacing thermostat and hoses

Slightly off topic, but I have an 06 X3, need to pressure test the cooling system. Is there an economical adapter that threads onto the expansion tank so a cooling system pressure tester can be used? I see them in a few vids, but no mention of who makes them or where to get one. Thought you might know. thanks in advance.

Just have to Ask. Did you really Get rid of all air here. Or did you have to do it again.

I have a 2001 325ci and is squealing I don't know where its coming from can you help me

He has a chicken drum stick as a shift knob

This is valvetronic engine?

Just imagine the coolant being blue!

Great

Jak bym miał tak uzupełniać żeby tak wylewać tyle płynu to dziękuję. Ten odpowietrznik jest po to żeby wypuścić powietrze z układu. To w jaki sposób to robi to beznadzieja...

For BMW coolant: blue is true, green is mean

Hmm, I didn't know e46 had a electric water pump. Thought they was belt driven. Atleast mine is

why you putting green coolant in a bmw?

I m using pink öne. Am I wrong. Somebody say just add blue colour for my 2001 e46

Can somebody help me figure out why my cooling fan wont come on ive owned chevys all my life

what model is this car ? I am facing an issue with my 2003 318i model. All the sudden coolant leaked and every time I pour coolant and fill to the max and go for little drive. the coolant leaks and It went to red zone temp and I parked right away. So can you assist what can the issue be ?

the same system works on e46 1.9 77kw? 105 horsepower?

who told You the heater core has electric waterpump ?

Use Either BMW coolant of Peak for European cars - should be blue not green.

Damn green coolant u should of just left as is.. need blue coolant man. It's alright to top off but green coolant?

What does adjusting the temperature do?

Green coolant is one of the best you can use in a vehicle...

G11 or G12 ?

only use bmw coolant you could fuck sensors up

Hm. Either I forgot what the color blue looks like or this guys using the wrong coolant 🤷🏼‍♂️

And two kittens died after that - letting leak coolant on the street is not the smartest idea (animals love coolant because it's sweet but it's not good for their health).

Is the engine running

Some people don’t deserve to have bmw. That Wrong fucking coolant smh.

The E46 does not have an electric coolant pump.

What if you didn’t fill it up like this, do you just start from opening smaller screw and continue to add more coolant and then turn on heater?

*bro I had my e46 in the shop last week they replaced the coolant dispenser, seen like they didn't bleed out the system, I have the radiator light on is this why? Any mechanics here?* 🙄

You're going to fuck your engine up using that coolant, ive seen it first hand, i don't give a shit if you have a degree in engineering you're wrong, that coolant will destroy your engine slowly but surely. Spend the extra 3$ and get the proper stuff.

Did you know? BMW has figured out a super secret coolant formula that magically protects BMW internals. Unlike those yellow or green coolants. Those things will DESTROY your BMW instantly!!! /sarcasm off

Yellow water only for BMW is better

I have to keep adding coolant about once a week now. Has that ever happened to anyone? I had water pump and hoses replaced last month.

Wrong coolant, you should use either G48 coolant or genuine BMW

What if my car still runs hot after I bleed it..
