Any reports of this issue on the base v6 958? Assuming a similar assembly design and pipe/housing union, I would figure it to be at-risk.

Never heard of this - and the V6 is a VW engine, so much of the design is different from Porsche designed engines (the V8's)

My 2011 Cayenne Turbo had a coolant leak. The leak came from the rear of the engine, a coolant pipe glue failed and popped-out, it let me stranded.

My indy shop took care of the repair, and went the extra mile to install a new water pump, new thermostat, new thermostat housing and a couple of hoses that tend to fail with age/miles. My CTT has 80k miles.

Sounds like they took care of everything. Can you share what it cost to have an independent do the work? And they wouldn't happen to be in NJ would they?

I completed the install at the thermostat housing, she is running good and back on the road with no leaks

I also did end up finding that connector clip, it was on the garage floor lol

Does anyone have a upgraded part number or part list to replace the rear leak location? Or is the only solution fabricating the connector? Attached is a picture of where I believe the rear leaks from, can someone please confirm.

Which epoxy did you use? Im looking at JB weld Hi-Heat stick, but not sure how that would work since its not liquid. Please advise.

The epoxy I used was the epoxy I use for replacing/installing golf shafts in the club heads. It was a bit more liquid than I would have preferred, however it seems to have worked, I have about 3K miles on it and no problems.

The fit was quite loose, so I don't see much of a problem with the JB.... I would spread a thin coat on both surfaces with finger (wearing a glove) to insure full coverage and not getting too much excess inside when pipe installed. Twist pipe when installed to ensure complete contact and coverage. I used the radiator hoses to hold the pipes in proper position while epoxy set.

I feel like the liquid epoxy would work better sealing it compared to the putty, it kind of feels like play dough. Im not sure if you can tell me where i can buy some of that epoxy you used or something similar. Thanks for your reply.

This is something you can try ...https://www.jbweld.com/collections/e...weld-twin-tube

Thank you for your replies. I actually went to Autozone and they had the same one you attached the link too.

Thought I'd update the thread a bit. I had my thermostat housing replaced by the dealer. Cost was actually reasonable IMHO.

Here is why:



Surprisingly - the pipe doesn't feel loose on the bench, but on the car, engine hot, I could wiggle that pipe and it moved.

What's reasonable in this case? For a water pump plus tstat service which I'm gonna be generous and assume includes this repair (I didn't know about it at the time) I was quoted roughly $2500.00

deilenberger

The water pump must be removed to replace this part - so - that would be the time to replace it if you haven't already (I did - mine was relatively new..) - my cost was less than half what you were quoted, although they did say that they'd underestimated the labor on the job, my WAG was it would have been about $1800 if they had estimated the labor correctly. If you also did the thermostat and water pump at the same time I could see the price going around where you were quoted.

BTW - if anyone thinks I should sticky this (semi "common" thing to watch for on early V8 958's) - PM me. If enough think so, I'll stick it to the top of the forum.

I vote for a sticky
