Symptoms: immediate and dramatic coolant leak. Can pour coolant in and it drains out just as fast from the rear of the engine.
Do you have a Porsche Cayenne that was built from 2003 to 2006?
Porsche Cayennes during the 2003, 2004, 2005 and 2006 years use plastic cooling pipes under the intake manifold. They eventually all will leak. Porsche has updated them with metal pipes in their newer models and the dealer will charge you $2800 for this service to replace them.
At Richard's Auto Clinic Ltd We will perform the same job considerably less then the dealer with our Ex Porsche Trained Dealer Technician on Staff.

Solution: Under the intake were the black plastic pipes. In may particular case of the three coolant pipes, the larger one next to the intake manifold runner holes had a 7 inch long crack in it. These lines carry coolant at a pressure, and are apparently a known design problem in earlier Cayenne models. Porsche sells a kit for this (14 different parts, including o-rings) The large aluminum piece with the extra parts are all part of the kit to replace the 3 plastic tubes.
Involves removing the intake manifold to get to these parts.
