Lexus GX470 Throttle Body Clean and Burping Coolant for Heat

I'm back on my newly acquired 2006 Lexus GX470 and today I get today a little maintenance that will help with gas mileage and performance. The heat was warm, but not exactly what I expected so I decided to burp the coolant and we dive into the throttle body to do some cleaning. With over 250,000 miles on this truck it is worth looking at as every bit of MPG gains count in this thing.
