cooling system/steam port advice needed

[thealien]

I am putting a 2005 5.3 into my 1972 Jimmy. I want to plumb the steam port into the radiator correctly. I know some block them off and some put them into the water pump or thermostat housing. I would like to have it installed correctly into my stock radiator with the top hose on the drivers side tank and the lower hose goes to the passenger side. I have heard/read that it matters what side of the radiator this gets plummed to (pressure side/low pressure side?)? Should this be above the attachment point of the top radiator hose or could it just be below it? I really would like to do this right
I will eventually install a purge/overflow tank but I just can not right now.
Thanks
Mark

well, I can tell you how the LQ9 (6.0l externally same as you) in stock form is set up.

Top hose goes into drivers side of radiator.
Bottom hose goes into passenger side of radiator.
Steam port is plumbed into passenger side of radiator exactly half way between the top and bottom of the tank above the lower radiator hose.

Hope that helps,

Cheers,

Rufus
