How much coolant do you need for a Porsche Cayenne?

Why does my Cayenne lose so much coolant?
Your Cayenne will lose a little bit of coolant here and there over time due to evaporation from the reservoir. However, a significant loss of coolant over a very short period of time usually means a leak in the system. Sometimes a leak can be seen when you park the car overnight.
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.
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.
