His last post was in 2015. If you do the job, it would be great if you could take some pictures and post.Bumping in hopes the OP can re-upload the pictures to Imgur instead of photobucket - they can no longer be viewed.
I’m working on this as I write this, and yes, you need to drain the coolant from the expansion tank. I did not drain it from the engine block and it didn’t seem to be necessary.I am about to do this service on my car. I struggle believing that ALL of the coolant needs to be drained from the radiator and the block. Realistically, how much coolant do I really need to drain? Or, is it just easier to drain it all?
I finished this a few weeks ago and I’m with you. I drained the expansion tank, nothing else. Just let the coolant from the pipes drain into a pan, used a rag to draw a little bit of coolant out of the head/stat housing so that it would be clean and dry for some rtv and the new pipe O rings.I’m working on this as I write this, and yes, you need to drain the coolant from the expansion tank.

I keep having leaking issues with my hard coolant lines on my m54
Initial symptom was slow coolant leak with spray over front of inlet manifold and oil filter housing. I replaced the hard coolant pipes - I made sure to pull out the broken plastic from the original pipes and tried to clean the mating surfaces, but did not visualize them or sand them with fine grit. I used rein replacement pipes.
I had a huge leak after the first change - turns out I had ruined one of the o rings, which I only discovered once I pulled the car apart. I then replaced this with a genuine o ring and reinserted. After a few drives, I noticed the same coolant splatter on the inlet manifold and can see a small amount of coolant on the block, so I must be leaking again
Looking for tips
Should I sand down the mating surface
Has anyone had problem with these pipes from rein?
Should I use RTV?
I really don’t want to take off the inlet manifold again!!!!
Keen to hear about your experiences and thoughts!
