ok so i relooked over it, the one coolant hose is just a passage way, from the IAV i think its called ? at the back of the head.

so i have the hose coming from the back of the block on the coolant passge pipe, to the back of the IAV and from that it goes to the ? termostat housing ?

then theres one off the back of the block that goes to some unit( i dont know what its called im having a brain fart day) right under the throttle body. NOW on mine theres a hose that comes out the bottom of that and goes no where. but on any other one ive seen there isnt a hose coming out of the bottom. but i am looking at a b18 to compare

my question where does that extra coolant house route to ?

i searched and havent been able to find any kind of info or diagrams

some new info hopefully a little more help.

 

Some go to the fitting on the head that the upper radiator hose goes to, kind of underneath the distributor.
