This 2008 Porsche Cayenne Turbo came in with a catastrophic coolant leak. Anything poured in the reservoir came right back out the bottom of the vehicle. The newer generation of Cayenne did not suffer from the same plastic coolant tube failures of the earlier models, but we were able to find that a hose connection on the coolant distribution manifold on the back of the engine had popped out, they were glued in from the factory. Much like the 997, to fix this the piece has to be removed and welded, or replaced. Fortunately, the updated factory part comes with a threaded connection instead of glue.
To access this manifold the engine or transmission must be removed.
If you look carefully you can see where the coolant outlet separated from the manifold.
Here is the updated part from Porsche. The large hose barb on the left is the problem piece, but you can see on this new part the connection is threaded in instead of pressed and glued.
With the transmission out and some careful work, the manifold can barely be removed from the bottom.
Here’s a closeup of the connection after the part has been removed. The residue of the factory glue is clearly visible.
