gen III 3s coolant tube routing? Options

[match220]

First of all, I'm assembling this engine with parts from people all over the forums since I have an engine that someone attempted to part out. With that said, I have two coolant necks that both fit the head but are different from each other. The coolant neck that I have used looks more like the one in the drawn picture below, but there is no nipple where I have drawn the "number 2", there is only a large threaded hole that I have a sensor in for my Autronic ecu.

I pulled the picture below from the handy manual that is posted in the stickies, I drew on it a little to allow my questions to be easier. The picture is not clear as to where "number 1" is going unless it goes into the coolant neck(most likely), and also I should mentioned that my "number 2" hose cannot connect to the coolant neck bolted into the side of the head because there is the threaded hole there.

Basically, do I have the right coolant neck installed? I'm thinking that it is for a non-turbo 3s since it doesn't have the turbo water inlet on it, and what is the other one from? And is "number 1" running into the coolant neck like I think it is?



this is the extra coolant neck that I have that looks different from the drawn picture above but still fits the head. What is it from?


and this is the best picture I have right now of my other coolant neck that is close to the drawing above.

Hi,

nr.1 is the throttle body heat/idle water line, goes to the tb and comes back to the stainless water pipe
nr.2 is the turbo water line

if you doesn't have nr.2 you possible has the neck of a na 3S-GE -> have a look to toyodiy your statment is ok to me

the neck on picture nr.2 is the mr2 one

the best way is to get the correct celica 3S-GTE neck

hope it helps
