Can confirm, Route 66 will not cover any sort of hose.

It's pretty obvious BMW used a rubber that is not up to the temperature requirements here. I'd probably replace them all with silicone hose if it were me. They should hold up to the heat pretty well.

fireroasted, do you still drive with the engine cover off?

Any negative effects doing this?

Route 66 is covering the repair for turbo coolant hose leak. I pointed out that the hose that was leaking was only part rubber, and the rest was metal, and they agreed. Took a couple of phone calls, but they're covering labor and the one leaking hose (bank 1 feed line). I have to pay for coolant. My SA advised replacing the other 3 hoses as well (bank 1 return line, and bank 2 feed & return line), so I'm paying for those as well.

Overall, I'm paying for 4 of the 5 hoses being replaced, and the coolant, which comes to about $350 before taxes. Taking my car in next Wednesday.

I don't get it ...

OP says that all can be done without removing turbos (tedious, PITA, but it can be done).

Removing the turbos according to the book just opens you up to more things going wrong ... again.

True, but I'm not sure a I can convince the dealer to go the route of not following the book.

N63 coolant leak

This thread is very informative. I found that the two coolant hoses nearest the turbos both had bad leaks, and the t-junction also shows some signs of leaks. The right one is actually a little loose (second picture).

I'm trying to figure out how to proceed on a DIY project (the underlines below are links to sources).

My choices are:

1) cut off the BMW clamp and replace it with a hardware store clamp, with the idea that I'll probably have to do something later to make a permanent fix.

2) replace the hoses with a standard coolant hose (any idea of the inner diameter? 1/2"?) and get a tool and the original clamps.

3) Do #2, but use BMW screw clamps (are these different from hardware store clamps?).

Here is the link to all of the parts.

I would do #3: BMW hose clamps (or equivalent without the BMW logo) do not have sharp edges and are designed not to "bite" into the rubber as you tighten them.

Don't re-tighten them while they are hot though. Let them cool, and then re snug them.

Thankfully I haven't had to do this myself, but if I was to tackle it I'd use one of these two clamps, with the Oeitiker preferred if the sizing & real estate permits - we use these on man rated flight safety applications. Oetiker makes them in smaller sizes than -028, but ACS&S doesn't stock the oddball sizes.

From what I remember it is smaller than 1/2" id. It was more like 3/8 (just under 10mm). Look into silicon hoses.

I agree. I think putting new clamps on them is just pushing things down the road. Obviously the rubber is beyond its maximum temperature range for creep, so it is losing clamp load as the rubber flows under the clamp and hardening up at the same time. Even if you manage for it to seal for a while, I'm betting they'll be so brittle in another year or two of usage they'll just break and leave you with a real big issue if you don't catch it in a hurry. Yes, rubber pushed beyond its temp range will experience brittle failure and just fall apart! My E39 540i M-Sport used in TX for a year experienced a ton of failures like this.

Silicone has a much higher temperature range. Get some nice reinforced silicone hose and you'll be set. Figure on $3-4/ft, which will be cheap given how much hose you've got to replace. Use some nice hose clamps that don't cut the silicone - done.

N63 Turbo Coolant Lines leaking, e70 5.0i MSport

Hey guys.

Read some codes on the car today. Got a turbo coolant pump and turbo coolant return line error.

Apparently there is a recall on the turbo coolant pump 11V-521 Service Bulletin 11 08 11. Who has experience with this issue and recall?

By the way, these turbo aux coolant pump and line errors do not illuminate your CEL. You do feel and smell the extra heat on the hoses.

Changed mine today.

Hi-Temp Silicone hoses and the M5 heat resistant wraps.

Very patriotic (even if you are french...).

What diameters are the hoses?

Hoses replaced

This went pretty well. I used this hose:

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

and these clamps:
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Unfortunately while the 18.5mm clamps work on the smaller parts toward the engine, they don't work on the larger parts toward the front of the car. The ones I pulled off say 21mm, which are 13/16". Rather than wait to order those, I just used 7/8" screw clamps. I may replace them later but they look fine. I think the silicone hose is less likely to decay with the screw clamps.

I had to cut the hoses off. They were pretty loose at temperature (but it was 32 in the garage today so they were tight).

The instructions for the coolant 'burping' were not very clear about when the two caps should be on or off, and I got conflicting information on the web.

The secret menu says that the coolant was 102 C at running temperature, and the oil was 98. For some reason I can't read the MAP thermostat through ISTA/P (I get a weird error).

This was about a 2 hour job and I'm pretty confident it went ok. Only a test drive and a trip to visit the mother-in-law will tell.

N63 Turbo Coolant Lines leaking, e70 5.0i MSport

Hey guys.

So I was still smelling some coolant (could have been left over from the old leak) when I came across a T connector that is full of white and yellow residue (this is a borrowed image from Google to show the location. I was not able to take a good photo since it was under the intake plenum).



Removed the right air box (from the front of the car) and the intake to the turbo and found this. 2 of 3 enlarged part of T connector have broken off inside the hoses (one of the legs that's broken is after I pulled the hoses off). As you can see, the other 2 legs are missing the enlarged part of the nipples. Oh ya, it's plastic and right under the hot turbos !!!



Got a brass T connector from Autozone and replaced it.

The T Connector is part of Hose 17127576363 (Item 7 of the photo below). The hoses are in terrible shape but I did not have extra 3/8" silicone hose laying around so I could not replace it yet. The sides of the T go to the engine heads and the main part of the T is connected to the hoses going to to right intercooler. I did not dig on how accessible the hoses to the heads are, but I will next weekend. I did not want to fiddle and start pulling stuff when I know I do not have hose to replace it.



More Photos from AMP:

https://www.google.com/amp/s/bmwtech...e-leaking/amp/

Also, my auxiliary turbo coolant pump was also bad so I replaced that. There is a recall on this (#11V-521 Service Bulletin 11 08 11) but it excludes my car. It is kinda weird on which ones are bad or are good since the recall for the F07 says anything through 2/11 are affected, but the manufacturing dates on the last 2 pumps overlap. I think it is based on the connector, but I will write a claim to BMWNA regardless.



It is Item 9.



It was a fairly easy job. Removed the small coolant reservoir (this is the one for the intercoolers), disconnected some hoses (all have quick disconnects aside from one, which goes to the aux turbo coolant pump). Took it for a Test Drive, got back home and turned off the engine, and the pump was purring which was music to my ears !!!

There is a recall on that pump, I think. Was your car one of the ones in the recall?

No. Recall was up until 2/2011 on the F07. My car's manufacture date is 5/2011. Where would they have the part numbers for the recalled pumps?!?

This is a great fix. I need to perform this on my x-5. Is there any bleeding of the turbo coolant required after replacing hoses?

That photo does not show the 4th line changed.

There are 2 pairs you should change: 2 from the main cooling lines (one of the lines on my photo with the red hose) and 2 from the aux cooler (stays/turns on when you turn off the car, with the "turbo timer).


Also, if you smell coolant after you shut the car off after you change the top hoses, check that T-connector sitting on top of the engine block between the turbos. It's plastic and is likely to break and leak.

I have an x-5 5.0 I think you have a 550. The parts diagram for the x-5 looks a little different. I don't think I have a t connector btw the turbos. I will double check.

Where exactly is your 4th line?

Also I am not a big fan of pulling turbo cover off. It takes about an hour to remove all the other crap. And I am not sure I know how to remove cover without disconnection the two injectors on top.
