I have met/talked to about 5 guys that owned or have owned a 2006 CTT-S and asked them about their coolant pipes (if they have replaced them or have had problems with them during ownership).. all of them said they haven't replaced it.

Mileage range from 30K to 80K...

I have mine at 33K now (2nd owner - 1 year this October) and I got this coupon of 15% OFF for service/repairs (well up to $200 max) in a Porsche Dealership that I go to. Was thinking of getting this done (or not?).

What do you guys think? I still haven't driven this for long trips with fear that the pipes may burst anytime (sigh)..

 

I am in the same boat, but have an S 2005 with 40k miles.

A reputable Indy shop in San Diego quoted me $1895 for this repair.

 

I wanted to upgrade to GIAC or EVOMS, but i wanted to do the coolant pipes first.. aarrghh..

 

I have a 2006 CTT with 33,000 miles. Coolant pipes have not been replaced. The mechanic I use told me there is a good chance they will need to be replaced, but he would not do it proactively. He believes they will show some warning by leaking at the o-rings. That was his opinion, and I am waiting, hell I may not even have the vehicle that long. Just my .02 cents

 

that's the thing though.. I have read about 04-06 CS, CTT about coolant pipes but a few on CTT-S... correct me if i'm wrong but (is) the 06 CTT-S the last version of 955 production? could Porsche made it a bit better (?) than the rest of the 955's?

 

That's a good question and I don't know if there was a difference or not.

 

There is no difference at all on the CTT-s. Same plastic coolant pipes as every other year of the V8 Cayennes.

There is also no warning sign. It is a cracking leak, not something around the seals. The plastic just eventually gets brittle and one day cracks from the heat. When they break they will leave you stranded. Dumping ALL the coolant!! No roadside fix.

They will also cover your front transmission seal with coolant. A coolant that dries to a crust like a coral reef. Which then destroys the seal. The transmission and/or motor need to come out to replace the $10 seal. ( depending on which method the service tech decides to use)

The risk is up to you. It's really not a matter of "will" it happen. It's "when" will it happen. You will save a ton of money not having to pay for a tow and trans seal replacement. Not to mention the unscheduled down time.

 

1800 is way too high, the parts are 5-6 hundred and its not that bad of a job.

 

i'm trying to contact one of the local shops here in houston.. hopefully get a good rate from them.. i'm planning to purchase the parts for this.. what's the dealership in portland that sells these (aluminum pipes) cheaper than the other?

thanks Cole.. I don't want to go all through that trouble (and just pay this one time deal)...

Was waiting for the class action lawsuit we have going on here.. if I get the repair done in a local shop instead of a porsche dealership, i'm worried that I wouldn't get anything since it's not done from one of the dealership..

 

Last sentence in your first post says it all. Give yourself some peace of mind and get them replaced. No sense in having a fine machine that you can't take anywhere, anytime.

I felt the same way about my 04 CS before I had the pipes changed. I'd never drive it on the highway for fear of a sudden coolant loss.

I did the pipes myself a couple of months ago, for a total cost of under $600. If you are at all handy, you can do it. Otherwise, it was about a ten hour job. Expect a shop to take 7 or 8 so you might get away with another $600 plus at a local shop. There is nothing special about the job so you won't need to pay a Porsche specialist to do it.

 

BTW I think it's Sunset Porsche.

 

Thanks CdnRD - just sent Sunset Porsche an email inquiring about the aluminum kit.. peace of mind comes expensive these days ;-)

After this, I'll do the chip tuning..

Thanks 'ya all..

 

Does it make sense to do any other job while doing the coolant pipe, such as the water pump?

 

there is a guy making an aluminum 2-piece pipe to remedy this problem. I looked into it a year or so ago but did not think i needed it then. Im thinking differently now. The trouble with the plastic pipe and the newer replacement is that the intake manifold has to be taken off and all surrounding hardware, then slide a long one piece pipe in. The two piece eliminates all the labor in doing this. I will look for the site again.

 

There would be no way not to remove the intake. No matter how many pieces you make the new pipes out of.
