Porsche Cayenne 958 V6 3.6L thermostat location and replacement part 2

2011 and newer Porsche Cayenne V6 3.6L Engine Thermostat Location and Replacement Recently the truck started having overheating issues. When cruising along at highway speed the temp gauge starts creeping past 200° and I would start loosing heat in the cabin but if I floor it for a second or even just down shift two gears to raise the RPM all goes back to normal. The water pump was already replaced so I suspected that the thermostat must be the reason for my issue so I replaced it with oem unit and all is back to normal.
