If you are asking about the part I think then on CIS cars it mounts with a rubber bushing/stud thing. It has a rubber block in the middle and M6 studs that protrude on both sides. One side threads into the engine block and the housing sits on the other side with 10mm nuts coming down on top. Often the rubber part gives up. I have not torn a L jet car down to this level in a long time, but I think it was the same.

Yep - you are correct as I have just witnessed this first hand.

I see the coolant is green where it is pooling fresh and where there is dirt and soot it becomes an ugly brown color when pooling and also clear in small quantities when it is dripping slightly. Cool......

Will be pressure testing the system after work today to find the leaking area(s).

Okay, sounds similar. Just could not see anything in PET or maybe just not seeing the studs and nuts in that view. Seemed very odd to be able to move it around a bit.

Looks almost like working on some kind of aerospace assy. instead of a car down in there - AFM going into a curved shaped air funnel - updraft flap control - set for fuel burn in 3,2,1..

Found 3 leaks under pressure.

2 hose clamps were loose. FIXED

Coolant leaking from here red arrow. What is this? Cannot find in PET.

Blue arrow is suspect also, any idea what it is called?

I plan on calling one of the big 3 tomorrow for this part but??????

Thanks.

Parts Dept says this sensor is no longer being manufactured. Remove and plug up. Anyone know what I can use to plug? Size?

My error.
Thanks for looking though.

I am in a bit of a jam with this one. I think I got bad info on this part (sensor) from 1 of the big 3 since I can find what looks like this sensor at regular auto part stores on-line but not sure if it is the correct one or not.

Pretty strange. I can see them in the first post and in the second post and the http:// links open up each picture in an IE new window.

Sorry.....I would certainly really appreciate your and others advice and you probably have the part the other sponsor did not have or at least tell me size a plug would be appropriate.

PS: It seems to be a coolant sensor directly behind and below the short hose to the HCV into the block or the hose assy support.

Fixed pics. Had album set to private by mistake. My error. Had to fix a thread to find a fix for the 928. Thanks for everyone pointing this out.

Thank you so much. I missed it on that illustration. Thermo valve? Never would have guessed that description, but does make sense.

I will be calling you today.

Thanks again - you made my day!!!!

Talked with Roger @ 928sRus today on my issue and he took the time to go through my problems and how to save some cash on my other items I needed.

+100 thumbs up

I am on track to driving the 928 next week and on to Sharktoberfestest.
