After I change a thermostat, I fill rad. back up to full level. Run it 'till it reached operating temp. Shut it off to cool back down. Remove rad. cap, add coolant if needed and put coolant in puke tank if applicable. I know some systems that I have owned require burping such as GM. If your system has a bleeder valve in line, then open bleeder valve while running. You will hear air hissing and then coolant should start spewing out. At that point shut off valve. You've purged the air from the system.

easiest is to drill a 1/32" hole in the flat of the stat just outside the center "mechanism" before installation. lets the air come thru so it will fill completely & does not affect cooling & only takes 1 minute to do. On a tough case with air pockets in the eng cooling passages, jack up the front of the car as high as you can & gun it several times with it warm (stat open)

and as you are filling, squeeze the upper hose like the docs squeeze a bulb to help people breathe. It will work some of those sticky bubbles loose. Many newer cars have special procedures too. Mid-engine cars often require jacking and bleeders. Toyota V6s require filling the heater hose, many FWD cars have bleeders too.

The above is good advise and works every time. Ask me how I know.

When I do a fill on a smallblock I pull the heater hose off the intake and fill it till it pushes water out. Done this for some time and it works great with no problems.
Also did the hole in the thermostat thing as well.
