Turbo coolant line o-rings
Has anyone ever done this? I noticed a small coolant leak from the reservoir being lower after several weeks, turns out it is my turbo coolant line. The o-rings need to be replaced on them one comes in at the top and one at the bottom.
I was wondering if this is something that I could do myself?
I am having my steering rack replaced and I asked thems to find the coolant leak and this is the issue, they said it would be an additional $645 on top of what I am paying for the rack job.
Hoping it is something I can do but don't know, does anyone know if I can do it at home?
Thanks for your input and time for info on this matter.

I've done it, and its difficult by any standards.
Access is difficult, you may need to butcher your tools. The exhaust heat shields really need to go, which are a pain.
The oil pipe connections are flat flanges with card gaskets, and are fine.
The water pipes use O-ring seals. The upper connection (which is the OUTLET) tends to trap water and corrode. Firstly, that makes it difficult to remove the pipe (things get damaged) but6 it also means the sealing surface gets pitted, even when its cleaned out, so you may not get a reliable seal. Its not a good use of O-rings in this instance.
If your car lived in a warm dry climate, you may not get this problem.

However, I think its quite likely that if you tried to do it yourself, you'd wish you'd paid someone else to do it.
I found it a bad job, and the last thing I did on my car was rebuild the transmission.

I'm not a good judge of that. I don't trust dealers to deliver service and value, and don't have much feel for what's worth spending.

Yeah I think I will be doing that, they said it isn't real bad just minor, minor leak now but will get it done. Just going to wait a bit so I can recover from the shock of just spending $1612 for a new steering rack and new o-ring on the reservoir lines, new fluid, filter and alignment. It has been a rough 9 months.
I had both abc high pressure lines replaced $2000, then another hydraulic line replaced $863, coil pack $1900, and then the steering rack which was the $1612. Not including regular maintanence.
Love it but damn this is getting silly, the down time is more upsetting to me then the costs. Just when I get over the nervousness of every sound or thinking every leak spot from a parking spot is from you, which is not, then guess what yes you got it, it has an issue.
Might be going c63 or accuAir. I seen this sl55 that had the system on it which gets rid of the hydraulics and is better and does everything the abc system does plus more.
Might have a pristine cl600 for sell.
