You're welcome!
Open the heater core bleeder valve located in the frunk(big white plastic screw) and fill at filler in engine compartment. You will also need to bleed air from the radiator by opening bleed **** on the top driver side of radiator. (you will have to lift the plastic guard next to driver side headlight assembly). Repeat until all air is evacuated and system is full of coolant/water.
Until all air is bled from system, you WILL experience overheating problems. Good luck

Exactly. This is the most inefficient cooling system know to man. So it will take some time to bleed it right

Yea I use a snap on coolant bleeder...... for the engine and then do the heater core and radiator. Sometimes you have to do it multiple times. drive it. do it again... gotta make sure you get it all out
