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

Unless I'm mistaken it's the top one on the stock Radiators..the one below it goes to the overflow. Both are located where the Cap is.

Edit: other way around..lol

On the last swap I did into a 68 Chevy truck, I put it on the passenger side just below the radiator cap, that's really your only option, and the factory hose fit just about perfectly.

I don't have a pic, but here's where I'm putting it on my 72.

i welded in a 1/8" fitting in my rad. on the pass side, next to the return-would be the same if your top hose was on the drivers side, you could just weld/solder a fitting in on that side-i tried to keep the fitting high, so the water could flow into a little open space
my rad was an AFCO/LS conversion rad, thats why the hose is on the pass side
its an old pic, but same location, with the stroker engine i found one of those steam lines that fit the back and front, so all 4 holes in the heads have air removal
