Is this the order you did it in? If so, things are a little off.
The heater should be on full hot (center console turned up as well) with the fan on the lowest setting with the ignition on, but engine not running.
Then you fill and bleed.

At this point you could run the engine until hot, and keep a close eye on the level in the ET.
