I found some coolant on the floor. From the picture, the black rubber on the right side was wet with coolant.
In the mean time it has stopped but I have not driven the car since I found the coolant mark on the floor.

As can be seen on the picture there are two rubbers between the aluminum castings. One on the left and one on the right. It is the right one that was leaking or perhaps it comes from higher up in the engine although I somehow don't think so.
Any advice of anyone that had this problem before or perhaps has pictures of the fix?
Thanks in advance
See picture attached please.

 

If it is coming from the two rubber sleeve it is easy too fix but if it is coming from higher up you have to properly investigate where the leak is coming from. The sleeve are only protective rings and under you will found some o-rings easy to replace and not too expensive. See picture:

 

Wow JP, thanks for the reply.
Your diagram is of great help.
It indeed does not look like a lot of work.
I drove to the dealer and bought the two "O" rings required to do the job.
I only have to figure out how to NOT waste all the water in the system and how to bleed it again.
I have a manual as well but I cannot see any diagram as you have posted.
Where did you get the diagram from that you posted?
If it is from the normal manual, how did you search for it.
I have to say, you always have a good diagram to most peoples problems.
Thanks once again.....

 

jpflip is the real deal when it comes to help/photos I look forward to them lol.

 

My english being not perfect I am using lots of pictures to properly explain myself! LOL!!!

The diagram (parts catalog) is from Auto Atlanta. Here is the link :http://www.autoatlanta.com/porsche-p..._911_parts.php

I am not sure how much fluid will come out but I would put a clean bucket under the elbow (item 13 and 14) at removal and recuperate the fluid....If you jack the car from the back the fluid from the radiator is not going to move towards the back and this will facilitate the bleeding process....Bleeding. the easiest way is to fill to the top ( with the back of the car jacked up it is better), drive around with the bleeder valve on the expansion tank open for a week and fill when needed.... Cannot add picture because I am at work ;-)

 

I use autoatlanta for diagrams also and have ordered a few things out of appreciation lol. I have bled the system as suggested worked for me.

 

Hello JP
Thanks for sending the website. It really looks like it can be very helpful.
Please send about "Bleeding" when you are home again or PM me if you like.
Thanks once gain for sending...

 

Look at post #7 from And996tt of this thread, you will get a perfect explanation of the bleeding process:https://www.6speedonline.com/forums/...ed-refill.html

The clip he's talking about is on the expansion tank. You just raised it and drive like that and fill coolant when needed....

 

Thank you JP. I appreciate your help.
