Great thread! I noticed in the service manual they refer to "reverse flushing" with compressed air and water. I believe the majority of shops have some sort of machine that flushes the old coolant out. But that method will still not remove any of the fluid from the heat ex changer setup correct since it is separate? Only area where it ties together is the coolant overflow tank correct? So the DIY method seems to be the best route.

So in a nutshell:
Drain original fluid
Fill tank to max with distilled water
Drive car with heater on full blast. Get it up to temp and then do a couple WOT pulls.
Let car sit for a while
Drain fluid out
Fill with water again and repeat driving and cool down procedure.
Drain fluid out
Fill with 50/50 G05/distilled water mix to max level on overflow tank

Correct?
