What I believe I used was a fine-toothed ratcheting boxed-end wrench. I have a Craftsman set, but I think there are some good brands found at your local auto parts store: you want a fine-tooth one that will ratchet even in tightly confined spaces such as that bolt.



And/or I could have come in from the opposite side that you have your wrench: from above, rear by removing the shift linkage to gain more room to get my hand up on that side.

Another technique I may have tried was to unbolt the transmission crossmember in order to drop the transmission (using a jack, of course) enough to give me extra room.

Finally got the screw out. Ridiculous amount of force required... Next is fishing the line out.

It involves doing one line at a time, pushing, pulling, turning and finally you'll get it out.!

I believe that "bulky thing" is the transmission shift linkage, which I think I disconnected to ensure I have as much room to access the bolt holding the clamping plate that secures both cooler lines to the tranny. If I recall correctly, I was able to remove the bolt without too much fuss, even in the tight spaces; might have to "feel" your way around the bolt as once you get your hands and tools up in there I think you're then working blind. With any R&R (remove and replace), having the right and sometimes esoteric set of tools makes the work so much easier (extensions, fine-toothed ratchets, universal joints, ratcheting box-end wrenches, etc).

Well i just loosen the transmission shift linkage and was able to remove the bolt. Removed and replaced the outlet. Removed the inlet but can't seem to push the inlet cooler though. I will try again tomorrow bec its getting dark now. Luckily I have the special tools to remove the lines.

Just be patient and work slowly. Whenever it binds on something, feel around the obstruction to determine how to orientate (rotate) the line and how much force may be necessary to gently persuade (slightly bend) the line around it.

I used these cheap plastic ones from O'Reilly that still were difficult to use. Next time I have to work on such special hydraulic fittings, I will pop for a higher quality "professional" set of disconnect tools.

Finally replaced the cooler inlet and outlet. The Inlet is a PiA but with a little wiggle and pulling amd twisting it was done.

I didn'y have the BMW tool to remove these, I just got 2 open ended spanners and taped them together at the ring ends then used the open ends to pinch the fitting open. Easy

Ok did this last night with my neighbor . Had car on race ramps Blocks much more room to work around then on jack stands.

On xi the drive shaft gets in the way but here is what I did.

To remove cooling lines attached to tranny I used a craftsman 13 mm box end wrench to get bolt out. Don't forget to order 2 orings because once you remove that 13 mm bolts both lines come out of tranny together . To get bolt back i used duck bill or needle nose pliers once in you should be able finger tighten it.

Next the best way to get access and maneuver line I had to remove alternator and move the ps resivior . This allows you to twist and turn the line better without bending it , i removed and installed inboard cooling line from the engine bay.

I used a quick release tool to remove the inboard line from cooler and a foot down there is a plastic block holding the two rigid line in place to the chassis . I think it's a 10 mm bolt. That was a pain to get to but was much easier with alternator and the cooling duct out of the way.

I think on the xi you need someone else on the other end of the line to maneuver it because that drive shaft clearly in the way and was about to remove that but got it done without.

Can't imagine what BMW would charge to do this job but it took a total time of about 3 hours. Next time I did say I could do it in 2 .
