To have high pressure in the coolant system you have compression pressure escape into the coolant system. If you simply replaced the head gaskets without checking for cracks or having the head machined to eliminate warped head then you have pretty much wasted your money as the problem still exists. You will have to pull the head again and have it checked out. Put a coolant system pressure tester in place of the radiator cap and start the engine and see if there is a rise in pressure on the gauge.
Does it have a motor oil cooler cooled by motor coolant that could have possibly leaked thru? Transmission fluid cooler? Was there tell tale on the replaced head gasket indicating a leak? Condition of a replacement head is important, with no warps, cracks.
This is the location of the coolant resevoir. It is not uncommon for the cap seal to leak after time and allow for pressure to push coolant out. If it has not been changed in the last 3 years, get one prior to any other repairs. Do not allow this to climb over 90 celcius. It will do damage to the heads. Inspect any hoses around the resevoir area. It may also have a cracked resevoir. It is not uncommon. There is a place in Southern California called SilverStar Porsche/Mercedes recycling (866)307-7300. Great prices and service. Will ship. I have used them several times and they have always done great. Let me know if you need anything else.
Hi there its easy, first remove the radiator cap,
then you will need to remove the engine cover under the car held in by 8mm screws, then on the bottom of the radiator you will see a red plug, unscrew the plug with a flat head phillps screwdriver and coolant will start to drain, when it stops, reinstall everything in the reverse order and fill with new coolant!

There is a valve to control the coolant to the heater core. You can identify this by looking at the hose connected to the coolant path. When it is bad it didn't close so hot coolant keeps flowing to your heater core when the AC is on causing hot air. It needs to be replace. Don't be fool by checking the resistance of the terminals since it may tell you the solenoid is still good. Why, since the valve is stuck inside, so even the solenoid is working but it could not pull the valve. Good luck.
sounds like wrong temperature range thermostat , or new defect , i only use stant thermostat , also double check coolant level , almost always air traps after coolant service
