    1. open the radiator cap and make sure the coolant is full.
    2. run the car with the radiator cap off, top off as it gets lower. (I have a special funnel to keep air from going in and coolant full)
    3. once the car is warmed up, turn on the heater to high
    4. open the bleeder valve (it's next to the inverter) and allow air to bleed. It's best to attach a 5/16 hose (I believe that's the size) to the bleeder valve so coolant does get all over the place.

    Repeat the process a few times if needed. For the next few mornings, when the car is cool, check the radiator to make sure it's full, top off if needed.

    If you are talking about the bleeder screw directly in front of the inverter, that is for the inverter cooling system, not the ICE system.

    You are correct, that one is the one for inverter coolant. The one for the radiator should be further towards the front of the car. I get confused on those 2 bleeder valves.
