In the image below you can see the bleed screw on top of the thermostat. If you don't have this you can see the referenced bolt in the background near the injector

No I did not bleed the system. Maybe this is the problem then? Do I need to drain the coolant again or just pop that bolt?
I don't have a plug on the thermostat housing.
