I was working for Porsche back when these were new. I did a lot of coolant pipe replacements under warranty. The first one I did was at a time before the two-piece aluminum kit existed. Much later, I was in the middle of a pipe replacement job when they updated the procedure with the new kit. Our warranty administrator came out and told me the labor time had suddenly dropped by a LOT and she wasn't sure why. I went into the online service information and found they had updated the procedure OVERNIGHT, describing how to install the new two-piece kit. I was pretty pissed since I already had the engine down on the table! We had to call our factory rep to get me paid at the old rate one last time since I was literally in the middle of the job when they changed the procedure and labor time.
Worked at a Porsche dealer, remember working on older (5yr) higher mileage (50-75k) first-gen Cayanne's and finding plastic/PVC coolant pipes, think the replacement part was a $3500 aluminum piece.
VIDEOGRAPHY/ EDITING : This was really superb : great to see the majority of the shots focusing on manipulating the parts, rather than talking to camera. The focused-in shots will really help the home mechanic who might try this themselves. And GREAT that there is no incidental music continuously through the video ( this seems to be a recent trend in others' YT videos, and it makes them almost unwatchable : it's so distracting ! ). So thank you for a great video !
The king of speed himself struggling with smashing that pipe out! Get your self some 2.5 inch pvc cutters… they cut through plastic pipe and all kind of hoses super fast and easy! Leaves a nice clean cut edge too… love the channel, keep it up! I tried to post a link but I guess that got taken down by RUclips 🤷♂️ .
Having owned an Audi SUV, I can say it truly takes a master tech to work on these on a daily. Just horrible vehicles for reliability but great when they work
@@RichRotorhead A friend was left stranded by his delightful plastic water pump on his...wait for it...wait for it... BMW! It's such a shame, German cars look good, drive great...but in the end, their complexity combined with abhorrent reliability makes them *_JUNK_* (or Johnny rich).
Love the video - so happy my '09 GTS (957) does not have the plastic pipes (but it has it's own "quirks" to keep life interesting). I'm interested in watching _any_ work you do on _any_ Cayenne, as I work on my own car as much as possible.
Replaces MOST of plastic pipe with metal but leaves short hose attachment as rubber for "last mile" attachment. Didn't Toyota do this with the "hose from hell" on 2nd gen MR2's?
I'm the one that still drove with them plastic coolant pipes till now. 955 Cayenne 2003, produced 02.01.2003, Im at almost Scandinavian cllimate (thats why I guess).
This is definitely one of those "While We're in There..." jobs. I understand from engineering and space efficiency standpoint it's a neat design, but God help you if any of those OG parts fail. You got to pull the intake manifold to replace a thermostat or starter? And when the thermostat housing is pulled, you'll break the plastic coolant pipes? Dang Porsche - you could've done better. Thanks for showcasing this Jonny!
They revised the engine and fixed theese issues on the 4.8 engine in 2007. the coolant pipes are now alu, moved the thermostat to the front behind coolant pump. Even Porsche engineers makes mistakes. Nothing is perfect, but you can try.
That pick tool you use to loosen rubber hose connections, if you had another that was bent to say 30-45 degrees (instead of the 90 degrees on your current tool) I think it would work much better on those hose connections up by the firewall. IMHO. Always enjoy and learn from your videos.
Jonny, you are a consummate professional. You should be proud of the quality of work you do. Porsche (and BMW) should be embarrassed by the plastic shit they put in their products.
I’m I the only one that thinks these cars are badly engineered? To put the starter under the intake doesn’t make sense to me and plastic coolant pipes that run under the manifold is ridiculous. It’s like they forgot about those things and fit them in wherever they could . Doug DeMuro recently did a video on these older vehicles and said they are affordable to buy but you better budget on having the equivalent of a monthly car payment to keep up with repairs and have another reliable vehicle to use when it breaks down. I’m glad I found the Car Ninjas channel and am learning about all the pitfalls of owning one of these things. I do my own repairs on my Ford and have more than enough tools for the job but I doubt I have half enough for something engineered in Germany and I don’t even want to think about the price of parts. This channel is giving me a real education.
I didn't even notice it was a Porsche until he said. I didn't even read the video title when I got the video notification. Just saw lots of plastic coolant pipes and naturally thought BMW. Then that pink coolant went in and I was thinking....wait a minute.
Really good video. Intake manifold looks the same as the LS engine I'm working on now. Huge coolant pipes though. I thoroughly understand the reason for replacing the starter now. Damn, what a nightmare you'd have to go through, just to replace the starter.
The stealership recommends replacing the starter after it drowns in coolant like mine did. Mine was done as part of the lawsuit settlement. Strange that one wasn't. Seat removal is not needed to change the battery., simply tilt it back out of the way. I've changed my battery enough I think I could do it in the dark, blindfolded, upside down, with one hand. Lol....nice to see the pipes being changed.
Good to see the Ninja doing the coolant pipe job on that Cayenne S. I am thinking about making an off road rig out of a Cayenne. If I go with a 2004-2006, that coolant pipe replacement will likely be a job that will need to be done.
I have watched a few Videos doing the same job and you covered some steps the others didn't,also seems relax doing it.Almost gave me the confidence to do it but still not sure i want to attempt that.
Please make a video on generation one L7 VW Touareg 4.2V8. Many people buying generation one Touareg and Cayenne for overland builds and most have issues with system lean codes etc. look forward to videos on air suspension also.
Isn't that a Wonderful design to put plastic basically touching the engine hidden underneath everything!!!!! You would think the more expensive vehicle would have smarter engineers working for them!!!!
Nice job Car ninja. Whatever happened to the previous diesel X5 video. I was anticipating to watch that.. I hope the Mercedes GL engine drop would be taken on camera though? 😊
Bad idea to post that video. At first he was not concerned b/c Kansas doesn’t have an emissions testing requirement, but enough people let him know the federal EPA has been cracking down on performance tuners that (I assume) he decided maybe it was better to take it down.
While you’re in there, one should always replace the 2 plastic coolant tees and coolant return hoses behind the driver side rear of the cylinder head and replace them with metal coolant tees that can be purchased from JTR Stealth in Ca. Cheap insurance and will ensure a long service life of these failing cooling system parts. The partisan and second dart air pump brackets need to be removed but who would want to do this job twice? Replace it while you’re in there and never think about it again…
Do you remember when German cars were actually reliable, quality, & luxury vehicles. Always some quirks but hidden plastic pipes, plastic intakes, plastic thermostat housing & water pump! So many jobs begin disconnect battery then remove engine!! Yeah, not even surprising!!
For that lower pipe that you had to break, going back together I would of sourced OEM style spring clamps instead of the worm clamps you installed. Those will only be a problem later. They will either not keep proper tension on the hose, or the worm slots will cut into the rubber. Also, a pet peeve of mine, I’d like to see you using fender covers or blankets.
Love your channel, enjoying these videos a lot!! Glad you "exist" beyond hoovie's universe... I'm binge watching now Why would you put a starter motor among all that heat??? Solving an issue maybe but creating a (huge) problem.
Why not use Viton O rings? Durability and temp range beats anything else I’ve seen.

Those designers who came up with those plastic pipes in engines should be "insert bad word here". It is incredible how many baffeling designs that have been completely bonkers have been introduced into engines during the many years
What a completely asinine design job that was, Porsche. It's never been more evident that the car makers don't care one bit about serviceability anymore...lots of "reasons" why, but this design has all sorts of stupid in it, which Johnny shows us at every step (while amazingly not losing his cool doing it). The techniques, tools and methods Johnny uses here can be applied to many repairs, too. - Ed on the Ridge
My 4.8 turbo has a bit different design than that, specially the water pump and thermostat housing. I had an open thermostat and they were able to remove the housing and put new pipes without removing the engine.
Excellent job one of the best out there. Is there a link to the pressure tester you use in the end and what exactly is the pressure to look for when testing? Thank you
No link, but they're pretty common and easy to find. No pressure to 'look for'...you simply put 15 psi of pressure into the system and if there are no leaks the 15 psi will hold. If it drops, there's a leak somewhere.
German engineering makes me want a Toyota Corolla. Engineered intentional obsolescence to mechanically total the vehicles after a few years out of warranty. With clinical efficiency. Sure some wealthy owners can keep em running. Loved the video though--nice job--no moronic hype or yelling.
Based on the quality of the URO parts I’ve used, they wont last as long as the original plastic parts.But I guess if you don’t have to pull the engine maybe it’s worth it? If Porsche makes a replacement like those I would DEFINITELY be using those instead of the garbage URO parts.
I would have broken the thermostat housing, because it was the most expensive part, cut two o rings and folded the intake gasket in two spots during reassembly.
Hi Ryan, you must have received an early kit, before we started pressure-testing 100% of production. Very sorry you got a bad one, please contact us - thanks!
Gotta love those German engineers for choosing such a crappy design that surely will fail on every single engine eventually. Plastic engine pipes on a super premium car; thanks for caring about your customers!

Who would ever have thought that putting the Starter motor UNDER the intake manifold, was a good idea.
Isn't that where the Toyota Land Cruiser has the starter? I think it's a packaging solution. The shitty plastic pipes are the real head scratcher...

When the BMW tech looks at you wide - eyed and says it's a crazy design you know it's fuckin crazy
You made me laugh.As a BMW tech I agree with you 100%.
Great video. Always amazed at these crazy designs.
Indeed very weird design
Great video. Always enjoy watching a professional work. Ninja smiles the whole time he’s working.
Thank you...I am having this done now! Great to know the "mechanics" of it all. RH/Florida
Yep the best of German engineering, Toyota may have put the starter in the valley too but at least they didn't bury it under piss weak plastic pipes 😆
Love Johnny's working with the precision of a dentist. Me, I'd be yanking, scraping knuckles, and using naughty words.
And people say BMW designs are bad.Thease VW guys are two notches above.Good job Jonny.

Rather pointless blowing the ports out if there is shop towels still in them but I’m sure someone will comment

really URO parts, they'll be back within 3~6 months
what German engineer thought putting the starter under the intake was a good idea? WTF is that about.
