How to Check BMW water pump 

Thanks so much for coming by :) Happy New Year to You :)

@@GarageKing How you doing , I have a question , My Light kicked on for OVERHEATED , can i put coolant on the tube where you put water for the wippers or theres another tube for the Water pump i have a bmw x6 xdrive35i im jot quiet sure

@@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 :)

Thank you and nice take on my shoes !!!!

Hey thanks for the comment, appreciate that !!!

Thanks soo much :) I'm hoping the New Year is good to us!!!!!!

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html

Thank you good Sir !!

Thanks soo much!!!! And Happy New Year to you both :)

i guess Im kinda randomly asking but do anybody know a good website to watch new series online ?

@Zaid Jaxton Flixportal :D

@Leandro Aydin thank you, I signed up and it seems to work :) Appreciate it !!

@Zaid Jaxton no problem =)

Hey brother thanks for the comment, the pump vid has not been posted yet. I'm still editing it. The pump is located on the passenger side underneath the car. I can help you along if you need any advise. I hope to have the vid out in a few weeks. I used an aftermarket pump and it worked fine and even came with the new aluminum bolts.

@@GarageKing Which pump did you use? I'm having a bit of trouble. I replaced my pump and thermostat and I did the bleed process. I turned it off then ran the car for about 15 min and it started to overheat. I tried to do the bleed process again but it never turned back on? I ran a scanner and I got code 2E84. 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.

@@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.

@@GarageKing how long did it take to change?

@@leftylok83 Hey Thanks for the comment, and sorry for the late reply. If I was not filming it, probably 2 hours. Because I filmed it maybe 6-7 hours.

Thanks too much brother!!!! I so appreciate it !!

Thank you good Sir !!

Thanks !!!!

Thanks for visiting, I do appreciate it :)

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

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)

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

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??

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.

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

@@GarageKing Thanks!!!

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"

@@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 👍

@@jordanclarkson2010 Makes sense, coolant hitting the hot rad, I'm glad you got it all fixed up. Sometimes problems like these are the most annoying ones as they are hard to pinpoint. Glad you got it all fixed up. Enjoy the rest of your day !!!

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

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html If you are doing the test right, then most likely you need a new pump.

Not 100% sure, but it may be able to depending on how it failed. Opened or closed.

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.

Most likely the pump is starting to seize up

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)

Most likely its the waterpump failing and it cant continue to run when it should. Even if the thermostat is stuck it should keep running. I think you need a new waterpump and here is the video to do it ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html

Hey There, the pump is about 170 bucks amzn.to/3eKtG4n and I did the video on how to replace it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html

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)

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.

Yes, but it should be a powerful stream like in the video. If its a weak stream thats a sign the pump in on the way out.

@@GarageKing hey so i think mine might be on the way out, the stream is not as powerful as yours, and i have yet to get the engine overheated light. however after short drives my fan goes berserk and the throttle response weakens. i still think its overheating. do you think this is still water pump/thermostat related?

Do they all have an electronic water pump mine is a 2006 320i. I have I zero coolant stream when I do the 10 second gas pedal procedure. But when I start the car, there is a stream. The heater in the car is also cold when stationary but is hot the second i drive and then goes cold again once stationary with the engine hot and running still

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.

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.

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.

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. Congrats on replacing the thermostat, not the easiest job to do !!

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.

@GarageKing I appreciate the help. Its been 4 years since the pump an thermostat was last changed.

@@jacobthompson8078 Well 4 years, not unheard of, but the code does lean towards the pump being done, if you are curious what required to do it, here you go ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html

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

It should be similar, if its not strong your pump is beginning to fail and that's why you are overheating (not enough flow)

@@GarageKing Ok I appreciate it. I'm wondering cause when the car is running its strong.

@@PAPatriots1776 the pump is variable so maybe it has its moments

@@GarageKing yep fault code popped on today when I changed out the coolant temp sensor. thank you for your help.

@@PAPatriots1776 That is very good, I'm happy you were able to get it fixed. Good thing for the code. Thanks for the follow up.

Here is the video to replace the water pump if you need to ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html 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.

@@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?

@@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.

Not sure, unless maybe on the diesel its a different technique, or perhaps you need a bi-directional scanner?

Got it booked in Tuesday , over heated few days ago and before that heaters only worked on one side .

Oh no, usually white smoke means you may have a head gasket leak. You can get an inexpensive tester to make sure amzn.to/4297ow6

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.

@@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.

@@luisleal4169 Yes you are correct, and maybe try the pedal test again with even timing between the pedal pushes. I know once you activate the car you have to start with the pedal fairly quick, if you don't the car will think you are just pushing the pedal for no reason, there is a small window of time to begin the test.

You are probably not putting it into test mode the right way. When you do start it and the pump flows how much does it flow? If its flowing a lot then your pump is most likely fine

Hey there, I know the connection for the water pump is tight from the factory. Here is the link to the water pump replacement video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html if the connectors are not tight that will surely cause your problem. Also there is a tight ground wire you must secure. You could also look for a blown fuse. I'm not sure which circuit the water pump is on, but you could check that.

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 :)

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 :)

Most likely the water pump, here is the repair video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html

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.

Yes that is normal. Once you stop driving the temperature raises in the cylinder head (for a short period) so to prevent this the pump can run for a short period after you shut the engine off, this is normal.

@@GarageKing thanks man

@@yanibay Anytime

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

Hi there, I wonder if you introduced air into the system. I would try to bleed the system of air, and activate the pump, just like in the video a few times, as it pushes air out of the system. You most likely have an air lock "a big air bubble" in your system.

@@GarageKing i try these steps, doesnt flow . if was pump broken should overheating, right?u change thermostat too?

@@stoicadaniel1909 Yup you are right, if the pump is broken the car will overheat. Its best to replace the pump and the thermostat, as the thermostat is located right beside the pump.

@@GarageKing thanks, i replace only thermostat for now, and i wanna see what happent with pump. keep in touch. all the best to u.

@@stoicadaniel1909 OK sounds good, best wishes to you :)

Thank you !! If you would like to see how to change the water pump here it is ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html

Hey There, the E63 is MB and this is a BMW so not sure if the procedure would work. If you try it out can you let me know? Thanks !!

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.

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

you may have a stuck thermostat

@@GarageKing i think i have a stuck heater valve control..

@@karanveersingh301 That is a possibility, but usually if the heater valve gets stuck open then you just have heat all the time through the vents, if the valve gets stuck closed then you get cool air through the vents, but which ever way it is, I don't think it would cause the engine to overheat?

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tDL-tAivuDA.html 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.

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.

That I am not sure my friend. You can try and see if it works, if not then a bi-directional scanner will do the trick

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

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

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

You can also use a Bi-Directional scanner

Hey There, I did film the changing of the pump, but I didn't edit it yet, so I have about 4 hours of footage that I have to make into a 12min video. It can be done. You have to jack up the car, remove the underskirt, and if you look just behind the steering rack its there. There are aluminum mounting bolts, and you have to get ones ones as they stretch. Its not the easiest job, but if you take your time and allot a good portion of the day you can get it done.

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tDL-tAivuDA.html

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

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.

@@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.

@@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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K-JXuMHgVJE.html

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 :)

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?

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 ?

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

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

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

You bet
