Ok, I'll try to explain this the best I can.... I am finishing up my D16Z6 swap on my 94 LX, just hooking everything back up. There two hose connections on the intake manifold just behind the thottle body. I can't seem to find two lines tho. Can anyone tell me where those two go? They are side by side only 1" apart, I'm thinking that one of them was never hooked up in the first place, since I can't seem to find the line. Any help would be greatly appreciated.

And yes, I searched, I may have found my answer there but all of the pictures are gone, just empty links now.

sounds like you are talking about an IACV lines...

one runs to the FITV underneath the throttle body, and the other one i forget where it goes..

 

the coolant hoses? iacv? 1 side should connect to right under the throttle body to the fitv. and the other side to the coolant pipe thingy behind the motor.

 

they are two lines, side by side. about 3/8" diameter. what is the fitv?

 

definately sounds like the iacv.. the fitv is fast idle thermal valve, its on the bottom of the throttle body with two 3/8ths line coming out of it

 

thats it, the one with two 3/8" lines, where do they go, from fitv to ????

 

what would happen if i left it open?

 

Ha if you leave it open coolant will spray everywhere and your car will idle like crap when cold. those 2 pipes on the back side of the TB are attached to the IACV idle air control valve i believe. one line goes from that (IACV) to the FITV under the TB. the other open pipe on the IACV (back of TB) goes to the little pipe coming out under the vtec solinoid right behind the thermostat housing.

edit: see two posts down...

Can you take some pics of the hoses and stuff. Maybe we can help better like that.

 

ok, i sent you a pm. i am at work and cannot host pictures. but i just went outside and took a few pictures of my stock z6 to show u where those hoses connect (if i could send you the pictures to a cell phone that gets pix messages). to just explain it without pictures they go like this..

the IACV pipe closest to the TB opening (passenger side of the car) connects to the 90 degree bent pipe coming out directly under the TB opening.. under your intake pipe. the other IACV pipe ( the one closest to the altenator or drivers side) hooks up to the skinniest little pipe that is right behind the bubble part of the thermostat housing... located under a hose that is about 1" diameter...

 

you talking about the loop? MAYBE

 

no, not the loop, the smaller coolant lines. xxxjustinxxx is hookin' me up with some cell phone pics, i think i'm good now. thanks to all that replied.

 

werd. glad i could help. hit me up via text msg if you need an answer from me. leaving work.. comp works when it wants to at home..

 

hes talking about the hoses that goes from the pipe under the im to the iacv to the fitv then to another coolant source. On gsrs its T'd off at the front coolant hose place.
