Here is how to replace infamous coolant transfer pipe on BMW's V8 n62b44 and n62b48 using expandable replacement kit. The procedure is the same for following models 2002-2005 bmw 745li, 2006-2008 bmw 750li, 2004-2005 bmw 645i, 2006-2010 650i, 2004-2010 545i,550i, 2003-2006 bmw x5 4.4i, 2007-2013 bmw x5 4.8i
We use euro parts collapsable kit and i do recommend it, its been my experience on some other kits the front seal is wrong shape and doesn't fit at all

Good Job Man?? Perfect file to keep in my 7 series files for later date.. Thanks

[@berwhaletheavenger]

For the front seal, it's worth removing the water pump. The seal can be a real pig to fit correctly so being able to see both sides is handy. Great video though.

Great Video. Can you provide a link to purchase these items?

Trying to install the front seal, can't get the pipe to go all the way in. Does the flat part or the beveled part of the seal goes down in to the groove?

[@andrewilliams1981]

Would this be the reason my 2004 745i keeps running hot? Also, amazing video and I’ve been looking on KZbin for months and this is by far the best one yet!!!

[@Zeiten]

Thank you, well the leak from coolant transfer pipe might a reason for overheating but it also might be something else, inspection is necessary

[@andrewilliams1981]

That’s what I’m afraid of, I live in a small town with no BMW specialist. So like you can imagine it’s hard to get a mechanic to even want to look at it. I did have a small like in the water pump area and we discovered it was the timing chain cover was cracked so we replaced that and put on a new water pump and new thermostat, new transmission cooler because it was leaking, a new upper radiator hose a new coolant tank, new lower water hose and now the water comes out the rear tail pipe and it still runs hot. I’m hoping this is the problem. But I think it may be a blown head gasket too. I tried to put blue devil in it but it won’t hold pressure. Is this leaking transfer pipe a reason why it won’t hold pressure?

[@Zeiten]

Sounds like a blown head gasket, blue devil and all other stuff is gonna help you only for short period of time, the best course of action is to replace head gaskets but might be something else try to find someone to do proper diagnostic@@andrewilliams1981

[@andrewilliams1981]

[@mikeandsarahsangster4602]

I was supposed to just replace the the valve cover gaskets on my e60, and some how, I went down this rabbit hole.

[@Zeiten]

[@tjkoko2001]

i wish i would have seen these videos before i paid to do my gaskets and secondary air hoses, my two cents if you havent done it check out valve seals and secondary air valves if your already there might as well

[@chrisknowles2112]

What.about a 2005 e65 730d sport? Would this be my coolant leak problem?

[@garygatten1154]

Good videos! Would be cool if you could provide torque specs, sometimes they are a challenge to find. Why do you prefer this repair vs. the stint that goes in behind the water pump?

[@morganrambo]

Because there is two gaskets that go bad. One in the front and one in the back. If you do the stent it’ll only fix the front issue, and you’ll have a leak again from the back soon. So it’s easier to just replace both than fix and mask one problem.

[@MrJimmy12345100]

The washer part is confusing. How do I know how many to use and what size? I couldn't see where exactly you put them.

[@jamesonobrien1496]

Thanks for the video, about to tackle this project soon. I was going to ask about the valley pan replacement, but I see u already answered it. One other question: Does the intake manifold gasket need to be replaced as well? Thanks in advance.

[@Zeiten]

Yep it’s best to replace intake manifold gasket of course

[@jamesonobrien1496]

@@Zeiten Thanks again. Love working on my brothers 750li…NOT!!! Lol

[@Zeiten]

😁

[@solarag3d]

Does the pipe need to pass over the front O-ring, where the water pump is? Im finding it very hard to fit this seal and expand the pipe so the groove can be seen. If installed incorrectly and it does leak, and you go in there again, do you need to buy a new valley pan again?

[@Zeiten]

Yes valley pan seal is a one time use, it is difficult to install front o-ring but it is doable, the pipe must extend to the point where it can be locked in the middle

[@herold30]

Thx... Great☺️

[@Gloryonskosmetic]

How reliable is this pipe.? How long is it about?

[@frankenstein6071]

Great video I have same car and need to change knock sensors. One question, when change the coolant transfer pipe do I have to change water pump or can I still use the original water pump?

No need to change water pump unless it’s faulty

[@melwilson3170]

I have a 06 750li and im doing this job now I got the valley pan off and my pipe is metal not plastic. Does this mean it’s been replaced before or did some models come with metal pipe ?? Car only has 86k miles

[@Zeiten]

All of them are metal, one in this video is metal too, no idea why you thought it was plastic

[@thelegend6911]

I need help, I have a 05 745i and just the other day coolant started pouring out by my coolant reservoir from the small tube connected to the lower part of the reservoir. The small tube connects I believe to the middle of the engine on the front, anybody have any idea how to fix it??? Thank you

[@LogicDecoded]

You cant just use a new gasket on the valley pan instead of replacing the whole valley pan, or is the gasket not replaceable?

[@Zeiten]

No you have to replace the whole valley pan, other solutions don't work, tried it before

[@piotradamczyk8630]

I like your films. Could you please give me an advise? It is good to be coolant fluid between valey pan and coolant transfer pipe ?

It should be there, totally normal

What’s the name of the first video?

[@giansolari2839]

I know this is an old video. I’m running into a coolant leak (obviously) 650i N62 So when i took the manifold i could see coolant right under the knock sensors all along the sides of valley pan. When i open the old valley pan, should it be dry inside or there should be some coolant there? I don’t see signs of leaks through the weep hole. Thanks in advance, great video

[@Zeiten]

It’s always filled with coolant under valley pan

[@giansolari2839]

@@Zeiten thank you for the reply. So where do you think it could be coming from? I replaced The Valley yesterday (i beloved this was the issue since i had coolant right below the knock sensors) today i found coolant again, will take the throttle body see if i can spot where it could be coming from.

[@Zeiten]

The most common in this area is valley pan or 3-way hose from expansion tank to the heads, or this little black tube from water pump to valley pan also o-ring on water pump to metal long pipe that runs along valley pan to the hose in the back

[@burnjack291]

How do u know if the coolant transfer pipe is leaking? Reading more i just saw that if the weep hole is leaking by the water pump that means the coolant transfer pipe front or rear o-rings went bad. Now if u dont have a leak at the weep hole, but seeing signs of leaking at the valley pan that means i need new valley pan? And if i open the valley pan and i see coolant inside that is normal? Thanks

[@Zeiten]

Yep, in that case valley pan needs replacement but I would say since you opened it, it would be best to replace transfer pipe as well, valley pan has one time use seal

[@burnjack291]

[@michaellam4492]

Hello Tim. i have a lot of coolant leak behind the engine, wanna know is that coolant transfer pipe cause that leak???Thank you in advance

[@Zeiten]

Well in most cases it is valley pan gasket leak, it seems like it is between engine and transmission but in fact it originates at valley pan and goes down in the back. But there can be a leak through another component that is located between engine and transmission in order to reach it you’ll have to separate those two

Where would I see coolant leaking from if I need to replace the valley pan or transfer pipe?

[@tonyshortell6379]

there is a weephole at the front face cover by wsterpump drips out under pressure

[@taylorsons4303]

To replace the valley pan it will leak on the side or the back underneath the manifold. Front hole by water pump is the transfer pipe needs to change including the valley pan because of the seal.

[@joelgonzales135]

Hows it going brother. I have a 2003 745li and it's starting to leak alot of coolant from underneath the car. Worst case scenario how much would a job like this cost to get done?

[@Zeiten]

Need to be more specific, the range of repair costs is very wide and all coolant or most oil leaks end up underneath the car doesn’t matter where they originated, gravity

[@joelgonzales135]

Sorry about that. I was wondering the cost to repair the coolant transfer pipe. Parts and labor.

What’s can cause coolant to leak from oil filter housing 745li 2005 ?Coolant doesn’t go in radiator at all directly out the oil filter housing Have already install coolant pipe transfer

[@Zeiten]

Oil filter housing doesn’t leak coolant, there is a coolant cover (part number 11147504376) between engine block and transmission that leaks coolant and it covers everything under it which includes oil filter housing and other components
