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

Yes and I must be dumb because I am even more confused. One place it says the steam port should be opposite the radiator inlet. Another I read just below the radiator cap. I think after reading it the day he posted it and a few times since I would place the steam port just below the radiator cap. I just was hoping someone would confirm this?

Thanks

As with any BillaVista article, you probably need to read it a couple times to absorb everything. If you aren't running a surge tank you need to run it to the highest point in the system on the low pressure side...which will be below the radiator cap...which will be opposite of the inlet. :D

I think you're on the right track. What radiator are you using?

The stock 1972 Jimmy 4 core radiator. The radiator cap is on the passenger side and on the bottom of the radiator (where the hose from the thermostat housing will go to, (from his article inlet to engine (outlet from radiator?)))

On the top of the drivers side is where the top hose will go (outlet from engine, inlet to radiator?) Inlet, outlet, high pressure, low pressure I'm just confusing myself :laughing: ?

Now putting it below the radiator cap, opposite the inlet (I think) is opposite of what the early ZR1 corvettes did. They had a fitting in the top radiator hose that accepted the steam line?

They come in two sizes. 28'' and 34''. It'll have all the correct hook ups you need.

The Gen III/IV theromsat. Is on the inlet of the water pump vs the SBC which is on the outlet from the motor.

The steam line needs to go on the pass. side under the cap for the raditor you have The rad. outlet (pass.) goes to the thermostat. The rad. inlet comes form the water pump outlet on top.

Thanks again for all your help.
