How to Burp trapped air from BMW Cooling System/Water Pump test 

Thank you for this video, im about to change the coolant in my e63 but i didnt know for sure how to do it, ive heard all kind of storys like using compressed air to force the coolant through the engine or just filling it up and letting it run.. Good thing i checked this video first!

Worked with my 2007 Z4- Thanks for making the video!

You saved my life. I was adding coolant and wanted to bleed the coolant and cracked the bleed screw. It made a mess. I found a bronze replacement from my e46 that fit on my e92. Coolant wasn’t reaching the lower hose radiator as it should after. This helped me a lot and solved my prob. ✊🏾✊🏾✊🏾

Thank you so much

Ladies and gentlemen, I can personally confirm that this works on an f30 335i as well. I’m doing it as I type and I’m happy to say that my water pump is in perfect working order haha

Very informative ty for sharing

Thanks for this video! I'm learning about vehicles from awesome content creators like you!

Thank you for this man. I like how simple you showed it could really be. I tried to get some N55 specific E90 chassis vids. But most of them were for the N54 motor & I wanted to make extra sure I was doing it right for mine! :-)

Thank you.

Thanks man for the video, I had some gurgling noises coming from my vents when the heater is on, changed the valve, but still the noise was coming. I tried this bleeding procedure and the noise seems to have gone or at least reduced dramatically.

Bimma Joe - thanks for the posted Vids - Very informative. I have a 2004 BMW 325i E46 w/M52 engine package. This does have the belt driven main water pump - on the drivers side inner side of engine compartment - and there is an electric motor mounted with two hoses coming from the heater core affixed to the electric pump does run in key switch position one, heat on high, fan on low. This pump doesn't seen to force the water forward to the reservoir, radiator, thermostat or its housing. I do jack the front of the car up about 18 inches (of course setting it on jack stands). With the Key on in position 1, heat on high, fan on low, it still takes 20>40 minutes to thoroughly bleed the entire cooling/ heating system. Have found that a quick engine start with a mild engine rev (~3,000 rpm) and squeezing the two large upper hoses ( of course with the engine off) - is the most effective and a certain way to eliminate air bubbles throughout the cooling system. I'm not certain the electric pump in the cooling system is working @ 100 percent. These pumps are expensive: $140>$250 range for a new one Keep up the good work!!! Petey VW

I was doing a radiator removal and put in a new one but for some parent reason it felt like it wasn't really doing the bleeding procedure must be doing something wrong I'll try later on today or tomorrow morning thank you I enjoyed your video

Very good video..best I've seen on getting to point and staying on topic. on burping the coolant system. What year/model BMW is the one you got there?

Nice information

Thankyou

Thank

Nice video. Good instructions. When would someone use the bleeder valve located on the tank?

Great video and thanks for your time it took to produce it. My 2010 e70 3.0 suddenly showed "Low Coolant" warning signal. Check the reservoir only to notice no visible coolant at all. Added Coolant and everything seemed fine. Drove it for for close to an hour with no issues. Parked in the driveway. Came back to it about 10 hours later only to find a small puddle on the passenger side. Low Coolant warning displayed again. Pulled the splash guard and looked like coolant drips were coming from the thermostat. In your opinion, could this be from not bleeding or failing Pump and/or thermostat?

This procedure will help if the radiator fan activate at high speed?

I will try this on my e46 today thanks for this

hello and all the best for you. i have an issue, my 320i e91 2007 keep coolant temp at 79-82°. its not bleeding right or thermostat is dead !? thanks.

Do I need to have my battery connected to a charger or another car battery to prevent my car from dying? Or should I be good to just run the car after and test drive

my water pump shoots water upward instead of downward spilsl it up everywhere on top is that normal?

Hello. I got a question So this morning when I turned on my car there was no power at all none of the lights were on so I assume "dead" battery but when I went to check the battery I moved it around and had power again (seems the negative cable was a bit loose) anyways I drove the car for about 15 mins and I started getting the Overheating light display which surprised me because I have had everything that deals with cooling replaced so does the water pump need to be "reactivate" of some sort since I assume the car had no power overnight and reset some things?

Hey! Do I need to crack the bleeder screw or anything as I run the cycle or can I just leave the cap open and run the 12 minute cycle? I am doing a reservoir replacement and need to bleed the coolant.

My car was running fine, not overheating but I had to change top radiator hose, now I have no leaks but I also don't have any heat. I have been trying to bleed the tank but I don't hear my water pump kicking in

2:50 why is it making that noise? I’m trying to diagnose my F10 535i as to why it randomly overheated few days ago. When I do the bleed test it does the exact same thing full pressure..... slowing down..... Stop then makes that rattling sound and then full pressure again. When the engine is started and nice and hot the flow of coolant in the overflow tank is consistent flow without stops and when the heater is off the flow slows down.

Do all the newer BMWs have an electric water pump? My father is having issues with sometimes having a cold lower radiator hose which causes the engine to run a bit louder and a hot smell in the engine bay. It's one of the i4 twin turbo diesel engines on an F11, not sure if it's 2.0 or 2.5 I told him about doing this and he said that his apparently doesn't have the electric pump but maybe he is wrong. I found some manual which said to idle the engine with the coolant cap off and rev the engine every once in a while and do that for like 10 minutes, but that had no effect although it did cause similar spray from the little hole as in this video

Doing this on a bmw f20 116i, the lower hose staying cold. Just had rad changed and car been overheating. Done this procedure can hear the pump working but nozzle not squirting water like in your vid any tips?

Does this procedure work for BMW e65 2007-08?

Hey buddy, let me know if you are still posting videos got some questions about my BMW E90

How do I do this on my 5 series ? I need to check if my pump works ?

What if thermostat is stuck would i still be able to test my water pump

I believe my 320i with manual transmission has got an old school bi-metallic thermostat. What I don't understand is "what if the thermostat is not in open position?". I'll try this anyway....

Bmw ista says u should switch low beam lights on or the process will disrupt too early.

I bleed my coolant the first time and everything went good I did it a second time and I hear the water pump run but I don’t see fluid squirting like it usual does , and it’s topped off

so when you bleed the cooling system, where does the coolant go? Is it being discarded?Do you top up the coolant after?

A malfunctioning water pump will cause the engine to overheat

Will the pump shut off off on it's own?..Or just turn car off?

How to do this procedure on f11 535d xdrive n57z? This does not work,please help!

Hello, this may be an old video, but I am facing a problem with my e92 Bmw! When I turn on my car everything is normal until the oil temperature reaches 250, then is shows on my screen "High engine temperature" and the fan turn on on a very high speed! I did the same test before watching the video and but for 3-4 minutes and it shows the the pump is functioning...How can I make sure if I need to change the pump or there's something else to do to avoid this costly issue! Thank you

This dont work on my bmw e92 330d.. what do i need to change ? and what part number ?

Hi I just replaced the radiator on my car, is a 335i N55 engine as well. How many ounces/litres of coolant do I have to add before doing this burp procedure ?

So this not only tests the pump this gets all air out right ?

Should I add coolant before doing this process or after it’s complete because I added coolant and used the bleeder screw and coolant was spilling everywhere please help

Can i do this also like this on my 1997 e39?

I have done this and worked perfectly, but the problem now , this is keep started each time I switch the car on , or off , now my battery drained completely, can anyone till me how to disable it?

My 07 x3 won't heat. Coolant light turns on when the motor reaches center temp.

Just to confirm the engine is off right ? And the key is on the on position ?

What do you mean make sure the battery stays charged? I installed a new battery, should I be worried about this?

Do I keep my foot on the accelerator for 12 mins in order to bleed the coolant system? Or just just to start off? Please lmk thanks.

If it doesn't do this does that mean the water pump Is out? My hose came off yesterday and I refilled the coolant and it was starting to overheat. I tried this and the water pump didn't activate. Any help is appreciated thanks

Would of been a helpful video if you explain where to connect the battery charger...

Make damn sure you use at least a 10 amp battery charger while doing this - I used a 4 amp, and after 25 minutes the water pump was still bleeding when the battery died. My Light Control Module was then BRICKED - and made the car undrivable - no windows, no dash lights. Bizarro. BMW's circuitry put the car into BRAKE mode - it was immobilized. I have since pulled the LCM and sent it to a guy in Massachusetts who will allegedly reset the EPROM or some other such wizardry. Otherwise you have to pay to tow it to the stealer who will charge you over $2000 for a new LCM. Grrr

what about overheat egine...what is the causing problem sir

Does this work on a bmw e46 m43 motor ?

I just change water pump on bmw 335i 2010 like 4 month and now have the same problem again ,over heating and scanner saids water pump power reduce but wasnt original 🤷‍♂️🤷‍♂️

I did the bleed process once and then it wouitirn on anymore. I turned my car on and it overheated at 117 celsius so I turned it off. Why won't it go back on?

Thanks for the video. Just to double-check after letting 12 minutes of bleeding happen out of the system what's the next step do I just put the cap back on and start the car or does it automatically stop after 12 minutes and next step is just to start the vehicle and let the battery run for 5 or 10 minutes?

Could I do this on a used bmw to see if the water pump is bad?

What if my heater doesn't work or blow out any air!?

Should I do this when engine warm or cold

hy... will this works on 1999 E38 728i?!... i dont the pump electric or not

Why you are using battery charger? And can I test water pump without it ?

Hi will this work on X5 E53 turbo 3ltr Diesel

This hasn’t worked for me, 05 e90 pre lci 320i 🤔

Hy, i try what u did here, but my pump doesnt work, no sound from her. Coolant temperature is about 80-82°c on highway and 94-96 in the city. no other error on ista. Is it right? 2007 bmw 320i. Thanks.

If you see your low coolant light on keep bleeding it until it goes away

Will this work Bmw e60

Will this work on a e90 320i N46

Will this work on the 2003 model?

How to bleed 08 750i? It's overheating

What happens if it doesn't run? You hear it start but everything shuts down?

Can I test water pump with out battery charger?

Will this Work on a e60 ?

Some People Leave the Coolant cap On is that or Your way is the proper..

Will this work on a 325 ci

Why can't you do this with the engine running, to avoid draining the battery if you dont have charger?

I replaced the water and the thermostat but when i do this i can’t hear the water pump:( can somebody help me ??

Will this work on an E39 4.4??

My coolant light came on yesterday say it was low. I put about a quarter gallon of coolant and it's still on. Someone told me it needs to be purged. Any thoughts? Thank you!

Do I need to loose that plastic Phillips screw on the top of the reservoir for the air to come out or no need to loosen the screw?

My water pump runs none stop and it finishes my car battery bmw 323i e90 2005 model

Will it work on 2012 528i x drive?

Cool vid bruh people charge 100bucks to do this

My water pump is running but no water is moving

You’re not supposed to have your cap open,you open it only to top off.

Bmw headquarters would like to know your location 😭

Didn't work at all

Lol wtf was this?and after it sounds like a dam diesel bruh fuck that I’m koo

Does this work on manual transmission f20?

Does this work for e46?
