Coolant DIY
1. My guess would be that the front and rear banks in the block are connected very well, since I got close to a gallon out of the drain plug #2 and barely over a quart from drain plug #1. I opened #2, then it took me some time to open #1 since I needed an open wrench to get to it, I could not fit any of my sockets in there.
2. I used 3 pieces of vinyl tubing, 5/16 internal diameter (Home Depot) to connect to all 3 drain plugs, so no spills and you can actually see if your coolant is contamindated (as opposed to collecting it as it drips off the side of your block and the lower cover, along with all the dirt). Mine was pretty red color, clear as baby tears

3. On FWD, plug #2 is the lowest among the 3, so I would strongly advise to open it if you want to get all coolant out. I managed to get out just a little bit over 9 quarts (including the content of the reservoir.
4. You don't have to take the whole lower plastic cover, taking off the rear bolts is enough to get your hand through to connect the tubing to the radiator drain plug and open it. There is NO way you can get to the drain plug #1 from under the vehicle.

However, in the case of the two drain plugs (I opened both of them), they were somewhat slow to trickle out. So what I did to get it moving was the step outlined in post 9 of this thread (step 5d).

My reason for doing this, the coolant changeout, is the extreme heat we have had down here, and I wanted as an experiment to notice what differences would exist.

I've adjusted a few things from the last time I did it about 7 months ago and because it is somewhat different from what I did in Mexico.
A lot of you do 50% water/50% coolant. I am a bit different going more water than coolant.
Here we have 1 gallon or 3.785 liters of Toyota Red Coolant (about $21 down here at Toyota).
2 gallons (3.785 liters each gallon) of distilled water that I have poured into old jugs.
1 bottle of Redline WaterWetter, that's .355 ml (about $9 at Pep Boys).
Total coolant capacity is 9 liters.
Thus, if we count the WaterWetter with the coolant, that will be 4.140 liters or 46%, while the water will be 5.40 liters or 54%.
As many of you recall, when I lived in Mexico I used a straight 100% coolant + coolant additive due to issues with water at higher altitude.
I recommend driving the vehicle around for about 15 minutes, letting the vehicle cool (usually about an hour) and then doing the coolant drain.
