Rad Flush - antifreeze question

Wondering where best to place the hose to flush that part of the engine block out.

. What I do is remove the lower hose from the radiator, remove the thermostat and reinstall the housing then insert a garden hose into the lower hose and force water though the entire system. I made a section of hose that fits tightly into the radiator hose then clamp with a hose clamp. By removing the thermostat you allow water to pass through the block. I also set the dash to heat to flush out heater core. When I first did this after using the Prestone Flush I was amazed at how much more stuff came out of the system.
