BMW E65 E66 How To Replace Your Water Pump

[@yahyashabazz5721]

No dude! Do not apologize for the video length! Your videos don't leave one scratching their head, you cover everything involved.

[@trunkmuzic7460]

Thanks Dude ! You saved me $500 ! Dont forget to put the gasket on before you put the water pump on like I did. I had the pleasure of replacing a water pump twice. Also I did not have to remove the Big Main Pulley at the Bottom, I used a 10mm wrench and created magic. FYI: flip the wrench around after every turn

[@juanitoperez8148]

Impossible

[@mehnlo]

If all the auto fix videos were as clean, detailed and understanding like yours. Very good!

[@WTNZ4JC]

I just replaced my water pump using your tutorial as my guide. Thanks man!! FYI: My crank pulley torx bolts were T45 and the large crank bolt is 27mm. Also the torque specs for the crank pulley bolts is 22nm and the for the water pump pulley bolts is 12nm.

[@4kdives]

You do not need to remove the 8 bolts holding the crank pulley, neither the AC belt does not need to be removed either all you have to do is remove the fan and insert an impact 27 mm remove the crank pulley bolts and and pry the crank pulley with a pry bar just enough to give clearance to the last 10 mm water pump Bolt that will save you about 30 minutes of Labor

[@rockielab7]

There’s a notch in the pulley, no need to remove the crank pulley. Rotate the engine using the crank bolt until the notch is lined up with the bolts.

[@fonissan]

Steve- I haven't found any comments on it so I thought I'd let you know about that one difficult bolt. The main pulley has a notch in it and I turned the crank to line it up with the bolt. What I did was loosen the bolt w a ratchet box wrench and it came easily with fingers. I lifted the top end of the pump out to free the rear facing outlets and worked the pump up and out with the bolt in place.(slid up pretty easily) Replacing new was in reverse order and this is where notch came in handy. I slid screwdriver in to keep pressure on head while I got bolt started. Getting it back in was a bit tedious using open end wrench side to side to tighten but I think it was still easier than trying to get that ac belt back on would have been. Hope this tidbit helps you and others. Your video is why I was able to do the job in the first place. Thank you for taking the time to help all of us. Tony.

[@outkastdog43]

Tony Orozco Thanks Tony for that find ..so what you are saying is that you take a screw driver and put it through the notch putting pressure on the head of the bolt and finger tighten first behind the big pulley to get the bolt started..I do not want to mess with the AC belt for sure

[@fonissan]

outkastdog43 Yes, one hand holding and twisting the other holding I believe a phillips just till it got started. Once it was all the way in I was able to fit a ratcheting boxed in wrench to tighten up. Also fyi, a friend of mine told me to put grease on back side of gasket so that it stays in place while trying to install the water pump. Hope it goes well

[@martingomez4357]

Tony Orozco the notch seems too small for the bolt to come thru; how did you do it? Update: was able to pull out the pump with bolt still in, as you mentioned(just wiggling it). One of the things I did when putting the new pump in, I trimmed off that bolt just enough to be able to fit between the back of the pulley and the engine. I just don't understand how BMW never made the notch bigger or that bolt shorter; go figure. At any rate thanks DIYsavecash.

[@Steve0815R]

Thanks a lot for your outstanding work. Your videos really enable all DIYers in the auto sector to get things done and safe hundreds of bucks... I just wanted add one detail about the reinstallation of the A/C belt. If you put the belt over the big center pulley and the A/C pulley and then put the big center back into place will automatically tension the belt. All you need to do is put one center pulley screw that goes on the left side first. Tighten the screw with your fingers as much as you can. Then out one more screw on the opposite side . Push the pulley fully to its seating plate and tighten that second screw again as much as possible by hand. Then put the remaining 6 screws in and tighten them all with the wrench. Done.

[@robertproulx9338]

Long videos are ok when that detail is needed. good job. much appreciated.

[@georgeleague]

THANK YOU, THANK YOU, THANK YOU!!! You most certainly saved me hours and hours of trying to figure out the oddities of BMW's. I mean, I can change the water pump in my Ford truck in about a half hour...BMW, not so much. And, of course, probably $1000 that I didn't have to pay the dealer. 2005 BMW 745i 160,000 miles. Got the water pump online for around 80 bucks, thermostat $41 and water pipe $16.

[@andrewhutchinson5627]

You do t have to remove the crankshaft pulley. There's a notch in the pulley for that bolt. Use a 10mm wrench to loosen the bolt and the pump with the bolt will be removed together. I do recommend to buy a shorter bolt when re-installing. (1-2mm shorter)

[@optimuzprime5868]

thank you! now what type and size of bolt would you or anyone recommend to make it a tad shorter to use with wrench? Thanks

[@DH-uf3lj]

This is what I came here for. Thank you for mentioning that you rock

[@c-los918]

I have a 2002 BMW 745li and love your vids and how you help so much! And you are always very knowledgeable of what you do. I always come back to your vids when something is wrong on my car or for DIY help. My car is making a lot of weird noise under the hood and recently noticed I have been missing a lot of water in my coolant reservoir. Thinking it's the water pump now that I see this video. I don't know what I would do without your help! lol

[@demonoffroad3566]

Great detailed video, I myself would not say it was to long more detail the better, and for those who think it's to long that is what the fast forward is for. Thanks again for taking up your time to make these videos!

[@gregoryray5712]

video on pump on that BWW video was the big help thanks

[@DIYsavecash]

excellent glad the video could help:)

[@john-williammccrory2167]

Super video as always. Thanks. Just did 05 750i. If I was doing again I would definitely drain coolant completely first as it's quite messy otherwise.

[@Gazman79]

Thanks great info. You can actually remove the water pump without removing the drive pulley, the bottom screw can be loosened and backed right off then tilt the pump backwards and jiggle it about a bit.

[@markcole1473]

Correct. On mine there were a couple of holes drilled into the back of the drive pully which when aligned with the bottom water pump bolt allowed it to come out easily.

[@JSVIDEOS]

Can you put back in without removing pulley on bottom?

[@AlM-tz8yx]

I used your video as a reference and really helped. Mine is an 03 so a little different. The water tube for the Alternator did not seat properly so had to take the entire thing apart again to fix it. Funny thing is it took me about 3 hours the first time and only about an hour the 2nd time. I love the way most of the bolts come out with fingers after a half turn. These cars are very well engineered. Having a tensioner for the A/C belt is a life saver. WHY DID THEY TAKE IT OFF LATER MODELS???? To save money on a 100k car? This is not a car to own if you don't know how or want to work on them. Local indy wanted $1,200 to do what it cost me to do with less than $200 in parts. Not OEM but I can change it myself many times and still come out ahead.

[@sa1408]

Very nice & clear. Mine started failing at 80k miles by making grinding noise. It's a mechanical pump for V8 (cheaper), but for V6 it's an electrical pump (expensive). Well done Chris

[@DIYsavecash]

Thank you for the kind words, I have heard also about water pumps going out sooner then they should, I was lucky to get about 140k out of mine.

[@Mr4parson]

hello thanks.. this works on my 2009 650i..... great job!!!!

[@pirate2998]

is it possible without big pulley removal? I'll do this to mine 645ci.

[@SmitfraudC]

My 08 E66, the tensioner is a T60. Also, no need to remove the crank pulley. Just use an open end 10mm wrench and loosen the lower bolt until it’s free. You can leave it in the water pump flange as you pull the pump away.

[@densmith1234]

Great video, very helpful! My only complaint is that you stated that you have another video to show "how you got to this point", but after I searched through your channel for 5 minutes I can't find it, nor do you have a link in the description despite numerous other links. You might want to incorporate a link to your other videos whenever you refer to them. I am very grateful for your work despite this minor inconvenience. I am not familiar with this vehicle but am working on it right now for a customer. Cheers!

[@JaimeMacDonald]

Just about to replace my water pump on my 2007 X5 with the N62. Thank you so much for a great informative video!

[@charlesjelks143]

Hey man your videos helped me so much . Just in case someone has the same issue that I had, you may want to do one of these to mention the alternator coolant pipe.

[@GERGE_GERGE]

Hi can you make a video about cooling system bleeding ?

[@kkv6124]

This is a very informative video, very insightful even when you made a rookie mistake you didnt edit it out. again wonderful video.

[@linusbacktrack3944]

I really love that you go over every detail, so please continue taking your time.. We need details :0) thank you for what you do

[@eltiarribero]

I had a leak from that short freaking pipe behind the wp on my e64. Since I had to remove the wp I went ahead and replaced wp and thermostat as well. A Pita but I did it following this video. Same n62 engine. Save me lots of mula. Thank you.

[@gencii.c]

You have the best videos, very informative plus you save people a lot of money, I hope to be as mechanically inclined as you soon.

[@DIYsavecash]

Thank you Genci for the kind words:) You will be, keep at it and learn:) Happy fixing.

[@kayrag]

Thanks a bunch, this is a huge help! I also found a bad water pump bearing, so just watching through your video is really helping get a lot of the gotchas out of the way! Thank you!

[@DIYsavecash]

Your welcome, glad the video could help:) Thanks for watching.

[@raptorcybersecurity]

Chris, thanks for this video! I changed mine after watching your video and it's working like a charm now. I am doing the guibo joint next.

[@InfamousMeskin]

Thank u for your video man hands down your explanation and work step by step got me threw a water pump replacement in about an hour tops with my 745 💪🏻 u rock bro

[@dougquaid4745]

You videos are very helpful I have an e63 and a lot of it is very similar , I feel confident to do stuff myself after the 'stealership' cannot do anything right without having to return

[@AlM-tz8yx]

A few add on's to your great video. I have a 2003 so I've got a tensioner on the A/C belt so easy to R and R. My tensioner for main belt is a T60. The T55 stripped out and thought I'd have to get a new one. Be careful not to lose the o rings in the hoses or you'll have huge leaks. Don't over tighten the water pump bolts or you'll snap off the head... ask me how I know...

[@DX784A]

This is a great video details are perfect I got a quote which was low for $700 well after watching your video I kept my money and it's done and running great and it was not a lot of time to do it! Thanks a million... or a least $700

[@e66ninja59]

Just a heads up; On those clips attached to the hoses, put your thumb over the screw driver when you gently pull up on the clip. I was changing out my expansion tank. I had too much elbow grease on a clip to my lower coolant hose........it popped off and I had to jack the car up and find it. My hand......my forehead.....smack......

[@andersjonsson5884]

[@joshuapena1314]

Amazing video!!! Super helpful!!! 10/10

[@EngineInformant]

DO NOT LOOSEN YOUR A/C COMPRESSOR TO PUT ON BELT! I can tell you with experience with motor out of car its almost impossible to align it back up with motor sitting on the floor out of car! use a long screw driver or pry bar to wedge it on as you rotate the crank pulley. those belts are made to stretch for this design. Also, as a note, these thermostats are made to stick open when failed for safety purposes. that said, an easy way to know if your Thermostat is bad is your car (not e65/e66 cuz on no temp gauge) will not register temp over base 160 degrees on dial and you will most likely get weird errors/fault codes like map sensor failure, emissions failure, cat converter not converting, misfires in multiple cylinders etc.

[@markjohnson4643]

[@boostedassasins]

Your videos are awesome. The problem I had before with my and not working and parking break malfunction was. I got my parking break rebuilt then reprogrammed. Then also my dsc module needed to be replaced and reprogrammed as well now car is great. Just so you know if that ever happens.

[@DIYsavecash]

Glad your car in working great, thanks for the update and letting me know the details.

[@boostedassasins]

Yeah I didn't know the dsc controls a lot of the cars driving functions, abs front and rear, works with the parking break, also sirvotronic steering, and also the dynamic drive.

[@leroywordlaw7077]

Hi Chris. Thanks for this. Can you add how long this process would take? Today I will be doing my E66 2005.

Thanks again for your videos, they are such a great help.

[@DIYsavecash]

Awesome Bryan, thank you for the kind words, Happy Fixing:) God bless.

[@JohnWalker-bg8kw]

If you look on the harmonic balancer there's a notch cut out if you hand turn the pulley until the notch fits over the last bolt you will be able to use a small 10mm ratchet to take it off I figured it out years ago by accident hope it helps you.

[@billycathy1989]

THX Chris from Germany, I have to do this procedure on my 745i

[@dreb8man]

Another great video! Did you take the 27mm bolt all the way out?

[@robbyd23]

in the process of changing my water pump but for the life of me i cant decide which manufacturer to go with. HEPU seems to be the go to right behind the genuine brand however my mechanic said it doesnt matter which one as long as the inner wheel (forgot the actual term) is metal and not plastic. Any recommendation and is HEPU the original supplier to bmw? Do you recommend changing thermo as well at the same time?

[@yesplease5278]

You dont need to remove the bottom pulley, just loosen those 8 bolts and you get the clearance.

[@a0ne7o283]

Hello Chris, first off I want to say thanks for the awesome videos. I was curious how the hepu water pump is holding up? I have x5 n62 and have fan issues. I swapped the sensors by it looks like I'm going to have to do the pump.

[@eastoaklandsartiebo-bo6718]

I didn’t have to remove a lot of things that he’s saying need to be removed. The air boxes were not in the way at all. I took the clamps off that attached the air to the center piece with the four bolts that sit center. I also didn’t have to remove the main shroud on top of the engine. It had no positive or negative effects on the removal of the water pump. Other than that this is a informative video. Thanks.

[@eastoaklandsartiebo-bo6718]

Be counted 6 bolts. There are only (5) bolts in my 2008 750i. Also didn’t have to take off the big pulley below the water pump to extract or put the bolt back in. Place bolt inside the water pump before installing it back in. Easy !

[@arasek101]

Hi Do you know the number of the O-rings in the small hoses of the BMW E60 545i V8 N62B44A cooling system? the ones that go to the water pump on both sides

[@ransomholbrook7428]

Big Short cut! You only have to loosen those eight T40 bolts on the crank pulley and not remove the AC belt. I loosen mine by eight 1/2 turns each, not taking them out, allowing the crank pulley to "cock" to one side. Gave me about 1/2" extra room to easily take out that lower water pump bolt. You just need make sure you push the crank pulley back on straight as you tighten the T40 bolts.

[@Mw-so6he]

[@DIYsavecash]

[@teranceerving9631]

DIYsavecash hey where are you located I need your help with my 07 bmw 750li

[@jimmyaber9500]

The crank pulley hub has a short (3 mm) pin that must be in its hole between two of the crank pulley bolts. The pin is short so it is not above the surface so the washer ring lays flat. the pulley can be installed without this pin in its hole very easily. This results in the pulley having a bit of runout and the bolts may come loose later. It is also a good idea to use either new pure coolant or a silicone paste for cooling system parts to lubricate the o rings for the pipes. This makes pushing the pump over the pipes easier and can prevent the o rings from slipping out.

[@DIYsavecash]

Great advice Jimmy:)

[@IanMackiewicz]

whats the torque value for the water pump bolts?

[@vigourdiy5084]

That's what I've been trying to figure out, the large diameter pipe is self sealing? w/o an o-ring? is the pipe's exterior made of some sort of flexible material?

[@sikumahomed]

Hi Chris, did the diesel like sound go away after changing the water pump?

[@raygomez204]

Thank you great video

[@andrewthompsonuk1]

I enjoyed this very well done video. It would be harder to do on my v12. That A/C belt looks like a real struggle. Manufactures no longer try to keep things simple to do. What do you think of those clip type rad hoses? I like clean off and blow into the coolant tank (pinch off any overflow pipe) with my mouth to do a basic pressure test before wasting coolant.

[@DIYsavecash]

Great call on not wasting fluid, I personally like the clips on the hoses, but the flat head screw driver one's on my old Cadillac weren't that bad either. Yes your right they do make it pretty hard on us to work on these cars sometimes.

[@semihyilmaz4699]

Do you drain the coolant first?

[@rgrant51rg]

A/C belt install technique used by a mobile mechanic: attach channel locks to compressor pulley with zip ties so that you can "shoehorn" the belt on. No special tool needed.

[@EEMCCOY1]

Good video, stiff as a whistle. Lol

[@gisellejohn]

[@joker90029]

Thank to ur video I was able to diagnose a strange leak on my e66. I had replaced the expansion tank due to a hairline crack and two days later I still found coolant loss at the bottom under engine. I took it apart today to get a closer look and found its that small pipe behind the water pump (25:45) easy fix and not expensive. Question is should I go ahead and replace thermostat and pump since I'm already in here or leave it alone? "If it ain't broken don't fix it " type of situation lol

[@ericgalvez6783]

Are you talking about the hose he pull out. I just replace my pump and it's still leaking. Wondering if that's what you mean.

[@kimberlymays8927]

Hey Chris, I watched your video very thoroughly. I went step by step. My thermostat housing is leaking a lot coolant from the back bolt. I've used sealant for the thermostat housing. Was I or can I use sealant on the water pump ,where the two pipes are to install it?

[@DIYsavecash]

Hello, to be honest I'm not 100% sure you can, so I would call or research more before you did that. Try to look up BMW E65 E66 coolant leaking from back water pump bolt and read everything you can in the BMW forum boards. My guess is maybe that small pipe is not tightly fitted into the slot or the o-rings have given out or maybe there's some old gasket stuck creating a little gap that the coolant is spraying from? or maybe the bolt is not seated properly causing the bolt not to tighten down as much as it should?

[@demonoffroad3566]

Have a question, when you pulled off the water pump you pulled out a tube maybe 3" long top left side of the intake manifold, it looked like yours was white and had two rubber seals on it. I heard that seal is a big problem leaking. Did you replace yours because that pipe that runs across the entire intake about a foot and half long is known to leak at the seal and you basically have to disassemble the block to get to it to replace a seal. I was wondering if you replaced yours with that bimmer fix product I've been seeing lately. Sorry I forget what exactly what it was called. But they say you just have to remove the water pump and put their sleeve into that hole to fix that seal leak.

[@DIYsavecash]

Hello, Could be the water pump bearing just like my nasty sound I had, or could be one of your tensioner or pully's. What I like to do is if it needs to be fixed and you have the extra cash just start at the tensionser belts and pully's and then go for the water pump. Check out my videos on the tensioners and pully's they'll help out. I have videos were I record all my sounds just start watching you'll find the fix.:)

[@ericgalvez6783]

Thanks for the video. I replaced my water pump but it's still leaking coolent. Any I idea what it my be. Im sure I put it on right. But I forgot to check that hose behind the pump. Could that be the reason. It look good but I didn't pull it out to see.

[@DIYsavecash]

BarberQuestStudent It should be called The "Heater return pipe" that's what it's listed as on ebay for parts.

Thank you for your reply. I got the part, im just going to change the water pump and thermostat since I have to take it out anyway.

[@Robsinthegarden]

DIYsavecash thanks again soooo much, changed water pump, thermostat and that heater return tube. Just a size note, some engines have a water cooler alternator, like mine did. There's another thin black tube that goes from the water pump down to the alternator, replace that while you're at it... And make sure you don't over tighten the screw's to the water pump... You can easily do that... Thank again... I love the detail in your videos. Gonna change my gubio joint next... Mine does the same thing
