When does coolant leak in a Porsche Cayenne?
Sometimes a leak can be seen when you park the car overnight. Often the coolant leaks out and then evaporates while you’re driving, leaving no tell-tale mark of coolant on the pavement.
What’s the best way to flush a Porsche Cayenne?
Be sure you have a large catch tray of at least 6 gallons capacity under the car, or lay out some plastic sheeting. Also keep in mind that coolant is toxic and attracts animals due to the sweet smell. Don’t leave old coolant lying around.
What kind of system does a Porsche Cayenne use?
Porsche specifically mentions the use of a vacuum bleeder to both evacuate and fill the cooling system. Airlift makes a very nice pressure bleed/fill system that allows you to do the job for around $100. It does this by attaching a pressure valve and gauge to the coolant expansion tank.
How can I tell if my Cayenne has a bad head gasket?
A compression test is the easiest way to check for a bad head gasket. Checking Coolant Strength & Condition – You should periodically test the strength and condition of your coolant to assure that you have achieved the optimum balance for your Cayenne. This is just as important for protection against heat as it is for protection against freezing.

What was the problem with the 2004 Porsche Cayenne?
The worst problem for the Porsche was an issue seen for the model years of 2003-2006. These models all had plastic cooling tubes installed at the factory. The tubes ran through the engine bay where it would get very hot and would end up cracking the pipes.
