There is no bleeder on this vehicle.
We need to do a couple of things. First, we need to fill the cooling system using this method. Lift the corner of the vehicle closest to the radiator cap. This will force any air out of the system and then use a spill free funnel to prevent any space from being filled with anything but coolant. I attached a picture of this funnel below.
Next, we need to allow the engine to get hot and the thermostat to open.
Don't worry about if it burps or not, just let it open and get hot and then when there are no bubbles, put the stopper in the funnel and reinstall the cap.
Next, we need to use a laser temperature meter to check the heater core hoses that lead into the firewall. With the heat on high, this should be about the same temperature on both lines.
If it is about the same temperature as the upper radiator hose and even between the two heater core hoses, then your issue is not the cooling system or heater core. This would most likely be an issue with the HVAC system.
Let's start with this and go from there.
