Just finished changing out the coolant on my Rav. Just a FYI to those who attempt this, even when you drain the block you only get 1.3 gallons out. My car has the tow package and has nearly 2.5 gallon capacity. Not a bad job, but getting to the block drain is a bit tricky - got to take off the exhaust heat shield and go in from underneath. Of course, you have to remove the under tray as well for this job. Also, took a while to get the air out of the system. I used the bleeder near the fuel rail. It works well. Car has 72K miles and I'm not keen on the 'lifetime' fluid - especially with the potential for WP issues.
