You don't need to have the engine up to operating temp, so the thermostat is open. There is a small bleed hole in the thermostat that will let the water drain through it and the air up past it.
Also, unless your old coolant is full of rusty muddy looking crap I wouldn't flush the system with water. I would rather have a little bit of old coolant in the system then plain water.
To replace the coolant, have the engine cool. Turn the heaters on. Remove the "radiator cap" which i on the clear attic header tank. Undo the drain plug on the bottom of the radiator. Undo the block drain to drain the coolant from the block. The block drain is on the left (passenger) side of the engin on the bottom of the oil cooler. It is a 10mm headed bolt that is right beside a support braket in front of the oil filter.
Once all the coolant is drained, tighten drain plugs.
Undo radiator air bleed on top of radiator top tank, its the 3/8 square drive plug, beside the small hose on the top tank.
Pour the new coolant into the header tank. Eventually the radiator will fill up. to speed the process, blow into the header tank to push the water to the top of the radiator. When the water starts coming out the bleed hole, refit the plug. Start and run up to temp. Recheck level. Done.
That's a very short, rushed explanation.
