It finally happened, the plastic coolant Ts failed on me and leaked coolant all over the place. In this video, I talk about what tools and parts I used in order to replace the coolant T's. Since the original coolant Ts are made of plastic, its wise to replace them with metal parts. The metal parts will ensure the repair will last the life of the vehicle. You can get the metal coolant Ts from the website below. Don't forget to check out my other DIY maintenance videos for the Porsche Cayenne.

Just finished the coolant T's on a 2005 Cayenne turbo. Your right about the hose bonding to the metal pipes. It's almost like the rubber hose was melted onto the metal pipe. Cable hose clamp pliers and silicone brake lube (syl-glide) was a "must have" for the installation.

JTR called me after I ordered the tees asking for permission to replace the 1" / 3/4" tee to 1" / 5/8" tee since it fits better. They knew exactly why I was ordering them. They said "You got this info from a RU-vid video, right?". I said "yes". They knew exactly that I was buying them for a Cayenne. Lol.

@DIYDanCars 6 лет назад

My T's fit perfectly as evident in the video. As outlined in the video the sizes I went with are -- One tee is 3/4" on all the three inlets and the other tee is 3/4" on the top inlet and the other two horizontal inlets are 1"

@mikaelstigberg5992 8 лет назад

Hello Dan, very good video, I see that your big water pipes seems to be change or have porsche change from 2005 modell, because i have Heard that also whas a big problem with early Cayenne,

@DIYDanCars 8 лет назад

+mikael stigberg Hi Mikael, yes, my Cayenne has already been upgraded to the metal coolant pipes. Unfortunately Porsche does not make a set of metal "coolant T's" so these parts will fail unless upgraded to metal. If your plastic coolant pipes have failed, now is a good time to upgrade to metal coolant T's as well. Hope this helps!

@cad-tastrophe3012 8 лет назад

+DIY Dan Do you have a parts number for those metal T's from JTR, or did you order by letting them know you needed 3/4 all around? I will be needing to do this upgrade ASAP. Thanks in advance.

@DIYDanCars 8 лет назад

+matt powell Matt, there are not any part numbers, you tell them the sizes you need in aluminum. My video at 8:37 shows what sizes you need. One of the T's is 3/4" all the way around where the other T is 3/4" on the "I" part and the other two outlets are 1" on either side. Hope this clarifies what you need.

@cad-tastrophe3012 8 лет назад

thanks buddy...I was having a hard time reading the markings on the ends. Please keep posting vids every chance you get on that CTT.

Porsche Cayenne Turbo Pair Set of 2 Vent Line Breather Hose. This connect to that part you have broken? 2008 Turbo

@buddy_b8735 2 года назад

is the longer thinner hose that runs below from the secondary T accessible from underneath? I have everything torn apart and cant' currently get under. If I know it's accessible from the bottom, I'll put all the new parts on and save that connection for last.

@alexwpalm 2 года назад

Hi Dan. I'm in the midst of this project now, among other things (i.e. valve cover gasket which is really helping with access). I see no mention of emptying the coolant or bleeding after installing the new metal Tees, which I received today. Is tending to the coolant system at all necessary? I would imagine bleeding, no?

@DIYDanCars 2 года назад

Hi Alex, the cooling system in a Cayenne is self burping. You will have to top off the coolant after replacing the Ts. After topping off the coolant drive the car and keep an eye on the coolant tank because it will probably need to be topped off again after it burps some air out of the system.

@alexwpalm 2 года назад

@@DIYDanCars Outstanding! Thanks. Ps, you're right...this sucks!

@Pollux95630 4 года назад

I can attest to the vent lines being brittle. Both of mine were starting to crack and leak coolant when engine was hot to the point they filled up the valley under intake and had coolant running out of the transmission bell housing holes. When I discovered it and touched one it crumbled apart.

@DIYDanCars 4 года назад

Using plastic for an application like this is just stupid. I'm still shaking my head as to why Porsche decided to do this. I guess you don't become the most profitable car company in the world by building quality cars. :)

@Pollux95630 4 года назад

DIY Dan they all do it...but seems German plastic doesn’t have the same durability as their Japanese and domestic counterparts. My wife’s ‘07 Dodge Caravan has crazy amount of plastic under the hood that is obviously way more durable than Porsche plastic.

@jorageakajoesgarage5521 3 года назад

Hi Dan. Any recommendation what alternate means removing vacuum vent line on air manifold the one in the back? There are 2 clips to be able remove it but one clip was broken off ( probably by previous work done). Maybe there is a special tool for this that you can recommend. Thanks

@flud78 8 лет назад

This is making me second guess looking at buying a turbo S now :( . How long of a job would you say this is? Too bad you didn't have a start to finish DIY. I'm a little bit of a DIY but I'd be nervous working on an in depth looking project like this.

@DIYDanCars 8 лет назад

I did the water pump at the same time so it's really hard to give a start to finish time. You do have to remove the intake manifold, driver side air pump, and a few other hoses and such. Most of your time will be spent trying to reach the coolant T clamps to get them off. I probably have around 4-5 hours in the coolant T replacement. The key is not to rush the job and take your time. If reliability is key a Cayenne is probably not the best vehicle for you. Even though my Cayenne hasn't been the most reliable car I have ever owned, it definitely is one of the most enjoyable. Good luck in the hunt!

@flud78 8 лет назад

+DIY Dan thanks for the tip. Can you do me a favor and write a list of ALL of the maintenance that you've done so far? And any online resources I could research for more information (forums). Thanks again Dan

@danielver4484 3 года назад

Hey Dan what about the brittle vacuum t that you mentioned, were you able to replace it with metal part? Do you have the link for that? thanks

@DIYDanCars 3 года назад

No, I could never find a metal vacuum T so I had to use plastic.

@danielver4484 3 года назад

Thanks Dan

@rush4ever1 7 лет назад

So these are the T's? Not the overall coolant pipes that need replacing also? Want to know where to look to see if my used turbo has been upgraded or not.

@DIYDanCars 7 лет назад

Correct these are the "coolant T's" that everyone talks about. The coolant pipes are under the intake manifold and the coolant T's are behind the engine near the firewall on the driver side.

@rush4ever1 7 лет назад

DIY Dan in reply to what you said, so both of these commonly need to be replaced? I had only known about the pipes not the T's have you replaced both of yours? At the same time? 50 something thousand miles you had when you did the T's?

@DIYDanCars 7 лет назад

Yes, if the plastic coolant pipes have failed more than likely the plastic coolant T's are not far behind. Only the Cayenne Turbo has coolant T's. Thankfully my coolant pipes were already upgraded to metal, but the coolant T's were original and failed in the 50k mile range. I had a set of T's made out of metal so this failure will never happen again.

@aaronhatz 8 лет назад

Dan, thanks for the great informative video. I'm getting ready to change these tees out this weekend and was wondering if you can tell me what the sizes of the coolant tees are. I can clearly see the 3/4" size in the video but having trouble seeing the other side. Also, my vacuum line at the back of the block has a broken tee exactly like yours in the video. Did you find a metal replacement for that one too? And if so what size? (My vacuum tee was so crumbled that it came out in pieces so I can't tell the sizes. Any help is much appreciated... Thanks

@DIYDanCars 8 лет назад

+aaronhatz The "T" that doesn't have anything written on it means it's the same size as the opposite side. For example if one side has 3/4" than it's the same size on the opposite side. I don't remember what size the plastic vacuum T is, sorry. I was unable to find a metal T and ended up buying a variety back at the autoparts store and that worked. Good luck and let me know how it goes!

@roxiecujo 7 лет назад

Hi Dan, I'm in the middle of this repair as I type. I have the T's in and wondering about plastic vacuum T and what the top of the T attaches to? I have oil spray coming out of it so it seems to be a balance line between the 2 sides of the motor. I do not see any line that would hook up to this T? Thanks!

@DIYDanCars 7 лет назад

One tee is 3/4" on all the three inlets and the other tee is 3/4" on the top inlet and the other two horizontal inlets are 1". I couldn't find a metal replacement for the T on the back of the firewall so I used a new plastic one from Harbor Freight -- sorry don't remember the size I used. My plastic vacuum T came out the same way. I don't know why German car companies are so infatuated with cheap plastic but for some reason they are... Hope this helps! Good luck!

@DIYDanCars 7 лет назад

I don't remember what that plastic T connected to as I did this job almost 2 years ago now. I thought it went up to the intake manifold?

@roxiecujo 7 лет назад

DIY Dan thanks for the quick response! I figured it out. it was the left and right bank vent line. thanks again, your videos rock! Frank

@12masterr 5 лет назад

hello,I'm a little confused about the other plastic t (vacuum t), so you replaced both coolant t pipes with metal, and what about the one on top that broke? thanks

@DIYDanCars 5 лет назад

For the vacuum T on the back of the firewall, I couldn't find one made of metal, so I had to use plastic.

@12masterr 5 лет назад

@@DIYDanCars ah ok,thanks. also, you got the metal t's ,but I assume you have to buy new rubber hoses to connect them? since you mentioned that you have to cut the old ones out!. I'm upgrading the top coolant pipes and don't want to take everything apart again in 2 months for the t"s!

@DIYDanCars 5 лет назад

If you buy the plastic T's from Porsche you will get the new hoses with them. Simply take the hose assemblies apart and replace the included plastic T's with the metal T's. Hope this helps.

@dxmcghee 6 лет назад

I’m slightly confused. What size do I need?

i went to lowes baught the 3 fittings for $20. shark bite brand. they are brass

@DIYDanCars 2 года назад

That's fine. Just make sure the coolant you decide to use can protect your brass Ts from corrosion. Unfortunately most modern coolants can't protect brass from corrosion.

@maxe.1204 7 лет назад

So you had to buy new hose sets from Porsche, remove the plastic T's and put back together with alum. T's. Or did you reuse the hoses?

@DIYDanCars 7 лет назад

When you order the new hoses they come with the plastic T's. I removed the plastic T's from the hoses and had them replaced with the custom aluminum T's. I would recommend if you go through all the trouble of replacing the plastic T's, that you not cut corners and also replace the hoses at the same time. Good luck!

@maxe.1204 7 лет назад

Thanks i ordered the new hoses (both T's, 955-106-323-50 948-106-035-51) can you share how you went about removing the factory clamps of that one T that are non-removable? Dremel? if so what type of bit did you use so you don't ruin the hose itself. Really appreciate the video and sharing with us.

No problem! I used a dremel with a small cutting disk and was very careful.
