Since the information is not easily found, here's a great little guide for you all installing a Prestone flush kit in your LS1/LS2 engine:
A = Water pump outlet to heater core, 5/8".
B = Water pump inlet from heater core, 3/4". <-- hose where the tee goes, in the straightest area you can use!
C = Water pump inlet / thermostat housing (in to engine from radiator), 1-1/2".
N = Water pump outlet (out to radiator, from engine), 1-1/4".

Clearly Prestone's guidance SUCKS! “Hose #2 runs from fire wall to top of engine. This is the heater inlet hose.”![Bang Head](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_banghead.gif)

I was going to flush my system today, but after reading on the forums here I'm terrified to even attempt!
First I don't know what I'll find (did the power steerig leak?), then I'm afraid I won't completely flush the system clean (the radiator cap has muck on it...).
Then there's the whole: dexcool vs green coolant debate....
I'm tempted to march on down to Chevy and let them do the work.
