Where can I find some directions on a proper flush once the thermostat arrives
Proper flush meaning proper procedure to burp air out? Easy, run it with coolant line going to wax thermostat (cold start device) disconnected as v8volvo mentioned. The bottom of the hose should be held up slightly so it's the highest point in the cooling system (above res). As the motor warms up, coolant will start to come out of that hose. Easy enough to catch it. Let it do that for a minute or two, and you're set.

The thermostat housing likes to seep on some older models where electrolysis has taken it's toll on some of the narrower mating surfaces; a little coolant safe rtv might help there. Mine seems to seep a little intermittently past the o-ring.
