steam vent routing.

[LQ9_ZR2]

My motor is finally in my zr2 im trying to get it popped off this week but im struggling on the steam vent stuff. Im running my stock 02 blazer radiator and resevoir so i would like to verify if teeing into the heater return hose is the correct place to run the steam vent that comes off of the throttle body.
I read this somewhere but it seems like there would still be pressure in the system...

correct me if im completely wrong, thanks in advance.

I would bypass the tb and run it to the port just under the radiator cap, basically to the radiator tank.

[LQ9_ZR2]

so basically tee into the radiator overflow tube? that would make things really simple

[farmtruc]

overflow is on top of the cap right? it's there to catch excess fluid when pressure is build up, not sure about routing it that way.
i'm confused, lol,

hmmm so do you not advise that? there isnt a constant flow of coolant through that tube is there? i dont see why it wouldnt work that way unless it drains my coolant system to my coolant res. that wouldnt be good.

If you look at the radiator on the pass. side, right in the middle should be like a half inch diameter small fitting that is already attatched to the radiator. That is where the coolant tubes from the bottom of the throttle body go to. If you dont have that small fitting, then dont worry about it, just put small end caps on the throttle body. If you dont have small end caps, then dont worry about it. You really dont have to have radiator fluid passing through the TB at all. I think its only for extreme cold conditions?

i dont really get what your point is here i already know i can bypass the TB i just would like to know where i should be dumping the steam pipe hose, because im running the stock blazer radiator and coolant bottle
