I tried to find pics at the time of the earlier post in June, but got sidetracked as they were off on another stored HDD.
I sourced the old links where I had gotten the pics from, but they're from '08 and no longer active to see. The driver's side is aft of the water pump (easy to access during the pump swap

). I thought the pass side was forward of the heater plug, but other reports show it aft of the starter (remove to access omG!).
Here's another pic.
As you can see ^^, it's just not worth the labor involved. Open the tank cap and the T-stat burp/bleed port up top on the T-stat housing and Drop the lower rad hose instead. You could also pull the heater hoses and add in some compressed air to empty the small amount in the heater core/lines, but I don't.
