Proper flush technique for coolant?

[Weasel]

If you really want to get as many shavings out as possible I'd probably pull the t-stat off (just 3 10mm bolts) and shove a hose in that bitch with the block drain bolts out. And the same with the radiator, maybe with the lower hose off in addition to the drain plug. As for the expansion tank, might have to just pull it out and hose it out separately.

For bleeding, just remove the plastic bleeder screw when you fill it and don't stop till coolant comes from both holes. (BMW was smart enough to put bleed screws at the highest point in the system on most modern engines)

I have not looked at any of this yet so questions are just off the top of my head...... It's dark and I can get an answer here faster than I can go look in the morning.

(1) will I need another t-gasket?

(2) I assume radiator drain screw is gonna be obvious, but for giggles is it left, right or in the middle at the bottom?

(2.5) where is the bleeder screw? The screw on the expansion tank?
