Steam pipe question?
Steam pipe question? So on my build, a random user from FB group pointed out that I need a steampipe port added to my griffin radiator.

While at the same time users have also ran LT1 on other custom rads and did not add the extra port. He also said he did not have any heat issues either.
My question is can I run the steam pipe into a catch can or vent it to the atmosphere? I dont have heat either btw.

If you tee it into a coolant hose, make sure is is a hose returning flow to the radiator. Those people that are not using the steam line are circumventing an important part of the LT1 reverse flow system. General overheating is not the criteria for using the steam line. It is to keep the cylinder heads evenly cooled by preventing steam pockets from forming as the coolant goes from the front of the head to the back. Even cooling is better for performance and engine life.

I used that exact radiator and just got done the install along with a EWP. I had a shop drill a hole and weld a bung to accept a 3/8 NPT to 3/8" barb brass fitting. I also needed to open up the bottom left corner threaded hole to a 5/8" NPT to 5/8" barb brass fitting for the oil coolant line.
OP, you can PM me your number and I can text you some pics I took of the modifications I made.

Verdad Gallardo Next question. Im not taking the rad out cuz I'd haf to take the turbo back off(I am not taking the turbo off again 
) so if I tap into the coolant hoses for the steam pipe, do i tap into incoming track to the water pump or do I tap into the out going tract to the rad?
I was thinking the outgoing to the rad idea because it'd seem like if I ran it to the incoming track to the water pump, it could possibly send air pockets through the water pump.
Thoughts?

I ran mine into the heater return hose. GM did it that way on one of the different cooling options on an F body. mine has been like this for over 1000 miles of daily driving in 100 plus degree heat in the desert and I have not had any problems. you can reference the diagrams on SHbox's website to see which is the return from the heater core. and a T for the heater hose is available from Oreilly's for either 5/8" or 3/4" depending on what pump you are using. I am running a vette pump so I have a 3/4" heater hose.

I got a blue 32mm / 1.25" Coolant temp sensor Tee off Ebay & found an 1/8npt 3/8 barb fitting to tee in the push loc hose I used with AN fittings... The stock steam pipe had pin holes all in it So I went that route... Works Great so far on the S10 ext cab SAS 4x4 
They have pretty much any color youd want!!!
