didnt bleed air out of coolant

i put in my new block heater last week.
i filled the coolant overflow bottle.
i dont know
i forgot to remove the 12mm bolt on the thermostat housing while filling it
i was thinking that i needed to crack it loose while running like the old 6.5l
a little air came out, that was it.
i ran it
after 15mins the thermostat opened. the low coolant message came on - i guess, when the thermostat opened it sucked in a bunch of water.
drove 1/2mile home
i parked the truck overnight
the next day i remembered the correct procedure.
i opened the screw and poured the fluid in
it took almost 1/2 gallon.
ive driven the truck a couple times for about 20mis.
drives fine
any reason i might have damaged it?
