How to bleed coolant without bleeder screw?
#2
It may just self bleed if you're lucky and only changed the t stat.
Last time I changed my t-stat on a trip last year I didn't bleed it and it was fine for the trip. Got home and then bled it properly. I had no waterfall noise in the heater core etc. Just fluctuating temps which I could see on the Ultragauge.
Why don't you have the bleeder screw -- pics of your setup?

To answer a bit more specifically what to do without a bleed screw, would be:
Raise the coolant bottle out of its little holder about 8"
Slowly pour coolant into the bottle, hopefully it should go down into the hoses etc
Slowly is key here
Massage the hoses around the engine bay as you do this (keep the coolant bottle elevated!), maybe some bubbles will come up into the expansion tank?
If you can't get it bled, best course of action would be to DRAIN the system entirely. Then refill it from scratch using above method.
I use a kids baby pool to preserve coolant I need to reuse btw when I do this. It lets it spill out in a few spots and you save it.

unless the first photo is the bleeder screw? It thought it would be on the at connector?

It looks like you have some non-standard parts in your coolant hoses. Not a big deal, but it may therefore be correct that the photo you posted is a bleed screw.
You also appear to still have the early style fan with the enclosing ring. Apparently those can develop cracks around the inside of the perimeter and then break apart, causing some major damage. You might want to think about changing that out for the Dorman/Hayden fan and clutch combination.
