For complete info on replacing thermostat including drilling a tiny hole on existing one:
Make sure you use 50% Toyota long life red low silicates radiator coolant to reduce corrosion build up on the tiny water bypass passages found in the aluminum cylinder head and preferably 50% distilled water,rain water or snow water.
I would pour the mixed coolant & water combination into the thermostat hole until full then install new stat and stat cover/hose tighten up.Start the truck on an incline or car ramps and start pouring mixed coolant & water combo into radiatior almost to the neck wait for stat to open which is about 10 minutes of idling then turn your heater on to high and hot (as well as your back seat heater controls for those with 4-Runners) and rev the engine back and forth but not too high.Re-top the coolant and continue to do so for one or more stat cycles.
Finally turn the heater control from hot to cold repeatedly and from high to low and place about half mixed coolant & water into overflow bottle and place stat cap back on,take for a test drive.Once engine has cooled off check the rad level and overflow bottle.
