Late last night, I happened to check the anti/freeze coolant tank and it was bone dry. It was way too late for stores so I filled it up using the BMW antifreeze/coolant mixed with Hinckley Purified water. Is this ok?

what color is your original coolant? mixing coolants is never recommended, especially if they are not in the same category of coolants. you could possibly get away with it, but it could sludge or have unexpected results in the long run.
You may have jumped the gun and cost yourself some extra work as its not an emergency if the overflow tank is empty, just get the right coolant and top it off later.
But since you mixed them already I would recommend flushing it all out and using toyota red coolant, only thing I run on my toyotas.

^^^ What he said, flush the stuff now and go with Toyota Red.

Thanks. How do I flush it? I assume the drain is on the bottom. Then how do I get to it?

On the radiator at the bottom, there is usually a drain plug where you can untwist and the coolant will flow. Most of the time they're plastic (white?).

You'll also need to drain from the engine block. I don't know the exact location of the drain on the 2JZ.

I'm so completely out of this. So would I have to jack the car up?

Not sure where it is on a 2JZ either, but I'd jack it up and remove any covers on the bottom of the engine bay so you can see the whole bottom end. Being an inline 6 it'll probably just have 1 plug, but it's usually near the bottom of the motor, just above the oil pan. You twist it open and it'll drain the block. I know on my 1UZ it's got 2, 1 on each side. You'll know it when you see it.

Oh yea, +1 vote for the Toyota red. Get enough of the full antifreeze mix (not the 50/50 blend) and then go to the grocery store and get equal amounts of gallons of the correct water (I think it's distilled but don't quote me). Auto parts stores should carry radiator flushing kits in case you want to just go ahead and flush your system now. If you get the 50/50 mix, you'll end up spending more in the long run even though it's a few bucks less than the full antifreeze.

look on the bottom of your radiator and you'll see a plastic stopper neck on the bottom. Remove it and let it drain. After you've drained it, re-install it and start filling you car with fluid. When you've got the radiator full, jack the front of the car up and crank the heat up to max. Start the car and let it run, keeping an eye on the bubbles coming out of the radiator. Add coolant as more bubbles keep rising. Keep doing this until all the air is out of the system. You might have to rev the car a few times to help some air move out (2500-3000 grand for a minute or two). If you want to be super **** about your coolant type, repeat the process several times until you're satisfied.
