ere is my 955 Cayenne Turbo Coolant Tees (or Ts) DIY Tutorial to help those tackle this in the future. First, you need to remove the intake manifold. There are several DIYs on this. It also helps to remove the secondary air injector pump on the driver side. You will see why below. You can remove the entire Tee assembly in one piece--only 4 points need to be unclamped. I labeled these points A,B,C, and D. All 4 points required me to razor the rubber hoses to remove them. Cable operated hose clamp plier is definitely required to do this job. It is also a good idea to remove the driver's side secondary air pump to give you more space for working on C and D. A and B are relatively easy to remove. C is the most challenging to remove as it involves blindingly feeling your way around to work the clamp off and to razor the hose. See pictures below to see area I used to unclamp and razor C. D required me to work from the side of the driver's fender from the top to undo the clamp, then go underneath the car and reach up through the cat to razor the hose off. Here is basically the orientation of the Tees when installed on the car. This is the razor I used to cut the hose. A and B are very easy to remove. C requires a lot of patience. It is right in this area. Zooming in to area... You can see it here... The full view of C... I went through from above, working on the driver's fender to cut C loose. Remove the secondary air injector on the driver side (DIY not shown) to provide ample space to work. Here is the opening where I worked my arm and hand to C. It was tough--very tight space. This is where the majority of my arm scuffs came from (long sleeves might've helped). This is also the opening I used to unclamp C. I unclamped D from above, working on the driver's fender. Opening looks familiar? It's because it's the same opening as C, except now you're looking straight down to the ground. Picture of D from above. Here is D from below the car. Picture taken from the left side of the driver's cat. Zoom in of D Picture of D taken from right side of driver's cat. This was the area and side I went in to slice D. This is also a blind reach, so make sure you feel for the right hose before slicing. That's all there is to remove the Ts! No engine pull necessary. Installation is reversal of the above steps. I used all new Porsche rubber hoses for the Ts and bought both the aluminum Ts (1 T sized at 3/4" x 3'4" x 3/4" and 1 sized at 1" x 3/4" x 1") for $50 over at jagsthatrun. For your new aluminum Ts, I used Porsche spring clamps to join the rubber hoses to the Ts. Some prefer the more traditional and readily available worm clamps. I just don't like worm clamps as I've had bad luck with them in the past of undoing themselves overtime. Choose at your discretion. I do find it helpful to lube up the aluminum pipes before joining the rubber hoses. Good luck!
