OK, assuming I have some air in the system, what is the easiest way to burp it? Is this correct?

Fill reservoir, raise the front end, remove reservoir cap, open heater, start car and let it run for a few minutes? I do have a 3/8 inch hole in the 12 oclock position of the new thermostat. So, it doesn't need to open in order for the air to escape the block does it?

Let neighbor's pesky dog clean up the anti freeze that spilled all over the garage floor!

And, yes, I did replace the thermostat after the temp spike incident.
