How to Check BMW water pump

How to Check BMW water pump. If your BMW is overheating the first thing you should do is check your water pump operation. It's easy to check and requires no tools at all. If it fails you won't have any coolant circulating and your car will overheat.

[@GarageKing]

@@RiichyyRiich123 hey thanks for the comment. The coolant can only be added to one place and one place only. The coolant reservoir as shown in the video. There is a link in the video when is playing that shows how to replace the water pump. At the end of that video I show how to fill the coolant properly. Just scroll to around the 1/2 way mark and there is a symbol in the top right corner click it and you will see the other related videos. If you have any questions just let me know. Thanks :)

[@blockchaineducationmanager5808]

How many hours of labour did it take you when you did it yourself? (Just trying to make sure my mechanic doesn't charge me a whole day or something crazy like that). I'm guessing about 2 hours or so?

[@GarageKing]

Hey there, it took me about 5 hours, but remember I was filming it. I could probably do it in about 3hrs. Here is the video if you want to see whats involved kzbin.info/www/bejne/gV6tiaiDfcyJgKc

[@Nando21o]

I have a 2006 330i N52 my car over heated the other day and I needed to add coolant since then my water pump seems to runs continuously not stopping until battery is drained my water pump also does not shoot coolant out like yours it shoots up like it’s aiming at my passenger mirror I have been told it could be relay or fuse but I personally think it’s the water pump what do y’all think ?( also my thermostat was changed about a month ago by previous owner I just got it with 205,000 miles the only things I know the car needs is o2 sensor)

[@Nando21o]

Please help I don’t want to spend the extra money replacing everything

[@GarageKing]

Hey there, ya could be your water pump. I wonder how it shoots up at your mirror? The only way I can think of that is if you took off the cap with the engine hot and it came flying out. If your pump is not circulating coolant properly for some reason (like a blockage or something) then the ECU will command the pump to stay on as the ECU (computer) doesn't know any better and it will just command it to stay on until the temp comes down (which won't happen if you have a circulation problem)

[@GarageKing]

Don't blame you, BMW part are expensive. (edited to move comma)

[@Rtrac44]

My coolant is also not a stream, it sprays upwards and in bursts not sure what the means either. But I think we are having the same issue. Did you get it fixed??

[@johnargue2977]

According to my scanner. Ac blower must on low. On low headlight switch to prevent sleeping. Key on, then hold pedal 10 seconds. Good video though. It also bleeds the coolant.

[@GarageKing]

Hey thanks for the comment, appreciate that !!!

[@Rhadoo89]

I just changed the thermostat and the engine still overheats when running at low speeds, start & stop. However, at high speed, it cools off quite fast. Is this likely a water pump failure? I haven't done the test shown in the video yet.

[@GarageKing]

Most likely it probably is, and a good sign is when you are driving faster the engine does not need the water pump as much as there is more air flow cooling the engine. Here is how to change your waterpump kzbin.info/www/bejne/gV6tiaiDfcyJgKc

[@Dannny1067]

Hey man brilliant video. I do this cycle and the water pump doesnt kick in and my cooling fan runs. Do you have any ideas?

[@GarageKing]

Hey There, well you may need a pump. A sure way to check to make sure is with a bi-directional scanner. Just make sure you are doing exactly as show for the test. It would suck if your timing was off and your pump was actually ok. If you go through and the pump still does not work, you can check if there is a fuse that is blown. (I'm not sure which circuit the pump is on) If have to replace your pump this is what you have to do. kzbin.info/www/bejne/gV6tiaiDfcyJgKc If you are doing the test right, then most likely you need a new pump.

[@tayoni800]

Does driving with insufficient coolant increase the chance of water pump failure?

[@GarageKing]

Yes it does, as the water pump is designed to run in coolant with no bubbles. When your coolant level get low you can introduce bubbles and your waterpump won't be as effective so the computer keeps speeding it up to get more coolant flowing, but there is not more coolant so what happens is your pump runs at a higher rate of speed and can burn out faster.

[@Flyingaceful]

Do you have to mess with the screw (next to tank cap) at all during bleeding procedure?

[@GarageKing]

No I didn't. After you run the car and its pressurized you can loosen that screw to get out any air, but its usually not necessary

[@Flyingaceful]

@@GarageKing Thanks!!!

[@gail6904]

after coolant bleeding this pump of mine is new aftermarket but it doesnt pump as strong as yours..is that a concern? also, should it cycle on and off or stay on all the time..i changed the coolant sensor and did as ur video to bleed and the pump only came on a few times thank u any way to check temp..the only time i hear my fan on is when the ac is on???? 2008 bmw 328i sedan

[@GarageKing]

Hey thanks for the comment, you fan will only come on when ac/defrost is engaged, or the coolant temp is hot (close to or above boiling) The pump should be ok, as it is variable, so cycles during driving and does not run full steam the whole time. Just make sure you you get all the air bubbles out so you don't confuse a weak pump with one that is pumping air/water mix. During the test it is suppose to keep cycling. If you have a scanner with bi-directional control you can test the pump and also see the temp when the T-stat opens and you can get a better picture of the engines efficiency.

[@haileytingzon8104]

Hi, I have a question I replaced the water pump twice already between only 4months. My question is why is it still breaking is there any problem that I could look of why my water pump keeps breaking?

[@GarageKing]

Hi There, 2 pumps in 4 months is way too much !!! A replacement pump should last a few years. The things I see.... 1. Make sure pump is properly bled, air bubbles cause the pump to run too much and can cause failure. 2. Make sure the connection (plastic connector) is good. Its a real ***** to get is connected and sometimes you have to use pliers to squish it together until it clicks and its got to be straight. A bad connection can simulate a bad pump when really the pump is fine, its just the connector wiggles out or someone broke it putting it in. 3. Ground - make sure the ground connector is good as a dirty ground can cause problems.

[@jordanclarkson2010]

I’ve had a few coolant hoses go recently on my N53 and when it is losing coolant quite fast it makes a weird buzzing noise but different to the one in this video. Could this be related to the Waterpump too? Or maybe just the pump running dry with the loss of coolant?

[@GarageKing]

You have a good theory with the buzz noise being attributed to a dry pump. I have never heard a pump run dry, but it's a possibility. I'm not sure what else it could be, unless the coolant you are loosing is spraying out and hitting something hot, or hitting a thin piece of metal and by the time the sound travels back into the cabin it sounds like a "buzz"

[@jordanclarkson2010]

@@GarageKing Yeah, it was the coolant pipe that goes to expansion tank and it was leaking onto the radiator when the car was warm, so I guess that would kind of explain it. I recently had a pipe fixed which goes to the heater matrix and when the mechanic bled the system he didn’t report any issues so could just be me worrying. The buzzing noise could only be heard from outside by the way. Thanks for the reply 👍

Im having a 2e85 bsd message electric coolant pump missing fault code. I find the water pump working and by following your procedure and its bleeding fine. Any ideas with regards to this code?

[@GarageKing]

If your pump is operating below spec you can still get that code. It could still be your pump. At times the wiring can cause this as well (you can get a replacement harness for the pump) but many times its the pump. You should have quite a bit of pressure when its operating (bleeding)

[@sanumiah953]

I put the coolant in but it's leaking out from the bottom, is it the water I need to replace or its the radiator, can you please advise, thank you

[@GarageKing]

The only way to know for sure is to lift the car and take off the bottom shield, this way you can see everything. If its a fast leak most likely a hose split. If its slow it could be from the a cracked radiator, or the waterpump.

[@jeffreyhammond5376]

My check engine light just came on my 328xi. Said the engine was overheating around 250F but there is a leak around the valve gasket. Would that be the cause or could there be more issues. Your help would be appreciated 🫶🏾🫶🏾🫶🏾

[@GarageKing]

Hey there, and thanks for the comment. Valve cover leaking would not cause a check engine light, or cause the engine to overheat. It will only result in an oil leak. Your overheating is caused by a problem with the cooling system, or the radiator fan. 1st thing to check is the coolant level because if you have a leak there won't be enough coolant for the pump to circulate and the engine will overheat. If the coolant is full its most likely the water pump, thermostat, radiator fan (or the relay or electrical system that turns the fan on)

[@mohammedhisham7032]

I had tried but the waterpump did not kick in…mine is 318i 1990 e90..this model mechanical or electric water pump?

I think yours may be a mechanical pump, but I'm not 100% sure. It would be easy to check. Just follow the fan belt and you should be able to see it.

I don't hear the pump kick on anymore. I wanted to see your video to make sure I did it correctly. I'm not sure if it's a bad pump or wire issue. Thanks for your help.

[@GarageKing]

@@kobe_goat_24 Hey sorry for late reply, I had to go into the raw footage to see the pump part # Its a Doorman 599-960 model. I did use a genuine BMW thermostat, but the pump is aftermarket. I found the connector was REALLY REALLY hard to push together on the water pump, and I even used a set of pliers to compress the fitting. I thought I was going to break it. I'm wondering if yours is plugged in all the way, I could see the plug not being seated an issue, because it would work, and then vibrate loose a bit and loose its connection. The 2E84 can be caused by a bad ground so make sure the ground terminal that you had to screw onto the front of the pump in clean and tight, and check the connector. I would be curious so let me know if that helps at all.

Hi, I have a 2009 bmw 323i. Knocking noise by the belt, the sound goes with engine even when you idling. I am wondering if it is not crankshaft,or water pump failure? Thx.

[@GarageKing]

Hey There, probably not the waterpump as they don't generally make that sound. I doubt its the crank as you would have a low pitched "thud" that raises and lowers with RPM. I think most likely you may have a bad bearing in one of the idler pullies for the serpentine belt. You can take the belt off, start the car and see if the noise is gone. You can alway use one of these amzn.to/3QHUnEZ to listen closely. I have one and use it quite a bit.

Here is the video to replace the water pump if you need to kzbin.info/www/bejne/gV6tiaiDfcyJgKc Now the first code is fine if your water pump failed, but I'm curious about the other two. If you changed the thermostat you would have taken the waterpump out so I'm wondering if you forgot to connect something fully and the plug wiggled out? I would check all your connections first. I can't see the Blue Devil sealer causing any problem but you never know. I tend to stay away from those sealers as they usually don't work long term, they are more of a temporary patch.

[@mdang3662]

@@GarageKing BMW 2014 X3 F25 you can remove the Thermostat housing without removing the Electric Coolant Pump. I changed out the Thermostat thinking it got stuck close therefore my car running hot. I did clean out blue gel inside the reservoir tank completely.... (A new Reservoir Tank and Electric Coolant are on order). Do you know if there is a fuse to check?

[@GarageKing]

@@mdang3662 You are right but, its still a fairly big job, most do both at the same time. Most times running hot is the water pump not circulating fast enough. I think there is a fuse, but you have to check your manual. I'm not sure where it is. Also if the fuse is blown you have to look at what caused the fuse to blow.

Thats good your pump is operating. If you are referring to it not running when the engine is running then it could just be that the computer has not commanded it on yet. It should begin to operate once the engine heats up.

@GarageKing i have fault codes 002E81 for electric coolant pump, speed deviation an fault code 002EF4 map thermostat mechanism. But the status of them are not currently present my code reader says. But they keep coming back when i clear it but says its not present. Also when i test my pump the way you do the stream is on for like 5 seconds then shuts off an then comes back on. But when the car is running its a nice strong stream. Should i replace thermomstat an water pump anyways?

[@GarageKing]

Humm, I'm wondering if your pump is intermittent. Because of the speed deviation I would lean towards changing the pump. The speed deviation usually means the pump is not operating within parameters all the time which is usually a sign it's going. Now it could go on for a while, or go downhill fast. Some last longer than others. But before you go changing the pump make sure your coolant is full. If it's low, that can cause deviation as there can be air in the system.

Hey there, the pump actually doesn't run when the car is cold, and its variable so as your car heats up it runs faster, then you also have your thermostat. You should still be able to do the test on a cold car.

[@luisleal4169]

@@GarageKing Hi, thanks so much for your reply. Checking if my understanding is correct: So if the car was cold, it is normal to not see the pump active until it heats up, once it starts heating the pump will start functioning. However if I do the test(start electrical system but not start engine, press pedal 10 seconds) it should trigger the pump and it should start working.

[@GarageKing]

@@luisleal4169 Yes you are correct, and maybe try the pedal test again with even timing between the pedal pushes.

[@GarageKing]

Hey there, you may hear the water pump, but its really quiet when the pump has failed. You can check the fuse for the waterpump, Its in the fuse box under the hood on the passenger side. You need to remove the fresh air filter cowl from the top of the engine, in order to remove the cover. There is mostly wires in the box and its made out of white plastic. I think its a 30amp fuse. It may be the only fuse in there, you can pull it and look to see if its blown. If its ok then most likely its your waterpump and you are going to want to watch this on how to replace it. Also if its blown, a bad pump drawing too much current can also blow the fuse. kzbin.info/www/bejne/gV6tiaiDfcyJgKc

It could be that your pump is not flowing enough. Sometimes they kind of 1/2 fail and they don't flow enough. If you pump if flowing, but not enough your car will still overheat. The other thing is if the system has dirty coolant something could be plugged, you may have to flush with water and refill with coolant.

[@GarageKing]

Hey thanks for the comment and thanks for supplying your engine code. You have the 4 cylinder engine so you may not have the electric water pump. I’m not sure. An easy way to check would be to look at your serpentine belt under the door and see if it’s driving a pulley that looks to be attached to a pump. The other thing you could do is call the dealer and give them your Ser# They will tell you what type of pump you have. If it’s not coming on when you test it, it could have totally failed so you could have an electrical pump. I would call the dealer and have them check for you. This way you know for sure.

[@tayoni800]

What causes a water pump to break down?

[@GarageKing]

It could be a number of things, as it's an electrical device. They break down with age and use, just like a starter motor or alternator. Some last longer than others. Good vehicle maintenance such as regular coolant flushes, and keeping the engine clean can prevent corrosion which can contribute to problems.

If your car is pump has a strong spray like in the video, there is the possibility that it could be the thermostat. If you have a scanner with live data, one like this is cheap kzbin.info/www/bejne/qnWvXqd3ntuoeqM as it only costs about 50-60 bucks. You can monitor your engine temp from a cold start and see when the thermostat opens (if it does) and then see at what temp the fan comes one. Very helpful.

[@GarageKing]

Hi there and thanks for the comment, not sure about the 5 series, but you can try to see if it works.

[@Barathy-fq3sy]

​@@GarageKing how ..i also dont no ...what u think about this

[@GarageKing]

@@Barathy-fq3sy You have to do just like in the video, you have to do with the gas pedal

[@bobbybrown4652]

Awesome Video 🙂

[@GarageKing]

Thanks for the great comment, I do appreciate it !!! Hope you are enjoying your weekend :)

[@Justificable401]

I did this to mine to see if that’s the reason why my fan keeps running on high but the water pump works because i have a flow of liquid So what could it be 🤦🏽‍♂️ I don’t want to spend almost $1k for something that’s not gonna fix the issue

[@GarageKing]

Hey there and thanks for the comment. If you have the AC on, or defrost the fan may run on high. Make sure the liquid is flowing pretty fast. Also look at your engine temperature gauge and see if the engine is hot. If so your thermostat may not be opening.

[@ricoco750]

Nice work

[@GarageKing]

Thank you !!!! Have a great weekend, and Happy Holidays to you :)

[@nrneal12]

As far as how to check it?

[@GarageKing]

You can also use a Bi-Directional scanner

[@MagarBhai-cj2ix]

Used full video tq❤

[@GarageKing]

Thank you !! If you would like to see how to change the water pump here it is kzbin.info/www/bejne/gV6tiaiDfcyJgKc

[@PartiBuoy]

So my water pump never failed but my battery died during a bleed so it threw codes I cleared them the water pump I assume works. It ran fine during the bleed procedure. So my fault codes were P2aaa b2aaa it’s electronic related so I guess that’s because my battery died so word of advice those codes aren’t too bad check fuses I did charge my battery at a whopping 6amp

[@GarageKing]

That's good to know and appreciate you sharing as it will help others. Thanks again and hope you are enjoying your weekend.

[@arthurtymkiv5035]

My waterpomp works well. But hood is hot. But temperature of oil is ok

[@GarageKing]

Well that is good, the heat to your hood is most likely not a problem, and when you are driving it should cool down with air flow. You mentioned the oil temp is ok, please make sure your coolant temp is ok as well :)

[@tylerangel4073]

Does this work on a 2 series?

[@GarageKing]

Good question, and to be honest I’m not sure. I never tried it on a 2 series. If you find out please let me know as I would be curious. Thanks :)

[@tylerangel4073]

GarageKing I just tried it I think my water pump is bad cause I didn’t even see the water coming out in the Cup lol but my bmw doesn’t seem to be over heating any advice?

[@GarageKing]

Hey there, if your water pump is bad it should overheat after a little driving. The one in the video that I posted overheated pretty quick and it was in the winter. When I did the test on the vehicle in the video and listened closely I could hear the buzzing on and off. When you tried it could you hear any sound? You can definitely hear a good pump run. After I changed the pump and did the test I could easily hear the pump turning on and off. If you car is not overheating your pump is probably ok. What’s going on with you car? What’s the symptom ?

[@GarageKing]

Its possible the 2 series has a different test and you are just not activating the test.

[@tylerangel4073]

GarageKing yeah I haven’t had any problems with overheating So your thinking my water pump might be okay? I just don’t get why it’s not shooting the water out

[@ObraMaestroChannel]

Good tips

[@GarageKing]

Thanks soo much :) Happy New Year to You :)

[@Christianhillis69420]

i can’t figure out my issue🤧🤧🤧 water pump is new, radiator is new, thermostat is new fan clutch new. everything working as it should but i keep getting to hot

[@GarageKing]

Hey there, make sure your fan turns on when it gets hot. You can test your fan by turning on the defrost. You don't have a fan clutch, but maybe you meant the fan relay. There is a fuse, and its on the passenger side in a white box under the hood near the cowl. BUT if your pump is running the fuse is fine. If you are getting flow like in the video, then you may have a bad sensor which is telling the computer your car is cold, when it is really hot so that's why the pump is not turning on. You can check this with a scanner that has live data. Start the car when cold and monitor the temp on the scanner, it should increase and if it doesn't then you have a bad sensor. I just did a review on a cheap one that works really well. kzbin.info/www/bejne/qnWvXqd3ntuoeqM

[@NobelHaile-l8d]

My water pump is good then what’s makin my car overheat

[@GarageKing]

Your thermostat could be stuck.

[@HighEnergy4201]

My 525i 2001 is ran by the belt

[@GarageKing]

If your water pump is driven by the belt then if you car overheats the thermostat could be stuck or you have low coolant because of a leak.

[@mvpml9937]

how to check electric bmw water pump working

[@GarageKing]

Yup this video shows how to check it, if your water pump is not shooting out water like in the video, then you most likely need to replace the water pump.

[@simdevils]

@@GarageKing But what if there is a leak? Will it still show shooting out water? My F30 is leaking a lot of coolant, i am hoping its the hose rather than the pump.

[@GarageKing]

@@simdevils I hope its just the hose. If there is water in the system it should still shoot water like in the video, as long as the pump has enough water to grab. SO if you fill up the reservoir and test it, it should shoot water out like in the video. I I did do the pump and thermostat replacement and that video is here kzbin.info/www/bejne/gV6tiaiDfcyJgKc

[@rochskier]

How is there enough working room to just drop your phone that deep in the engine bay?!?

[@GarageKing]

Right !!!! It’s pretty tight down there :)

[@suarezfamily3536]

hi our throw water out

[@GarageKing]

Not sure what you mean, but the stream of water should be pretty good, just like in the video.

[@nola5n045]

Problem solver

[@GarageKing]

You bet

[@jamalnasir2846]

I have a 2006 it stops suddenly on road then after some time it starts then again same thing i had to do this 8 times to come home

[@GarageKing]

You mean your car stops suddenly on the road? When your car shuts off if your temp high? If your temp is high you could either have a leak and your coolant level is low, your thermostat could be stuck, or you may need a water pump. There is also the possibility there is something wrong with your charging system, but then I'm not sure if you would have been able to restart 8 times.

[@jamalnasir2846]

I try to check waterpump is not working

[@GarageKing]

You most likely need a waterpump if the check did not work. Here is the video on how to do it if you want to try kzbin.info/www/bejne/gV6tiaiDfcyJgKc

[@akiempiranha4253]

Can weak battery cause the pump not functioning well ?.

[@GarageKing]

Hey thanks for the comment. Not normally, it should still run, but if the battery is really weak then yes maybe. Once you start going under 11V on most cars funny things start happening. You could always put a charger on it when you are testing it to ensure you are above 12V. Happy Sunday to you :)
