i dont know what connects to it


btw, i haven't been running my car like this, i just swapped a boosted z6 in and and doing final prep work before i start it and noticed it earlier

 

bump

 

Its for the IACV; it's coolant.

 

Don't start the car without hooking that up. Coolant will spray EVERYWHERE.

Yep, that looks like its connected to the water tube. Your PCV is under number 3 and 4 runners of the intake manifold.

 

do i connect the driver side or passenger side nipples of the iacv to that one?

 

Driver, then the pass side one connects to the FITV under the throttle body (provided you have one) or into the intake manifold nipple.

 

alright, i will check it out in the morning and see whats left cuz i know when i swapped the motor in i had both tubes from the IACV connected to something. thanks

 

ok, i got that one line fixed, now i have this one thats not hooked up (i have a piece of line there cuz i got pissed and cut it cuz i couldn't get it off). so now heres the new question, what hooks into this line?

btw, if you cant tell, its the one thats on the backside of the thermostat housing

 

is that connected the LARGE coolant passage thats connected to the intake manifold...i can't quite tell, but if it is, then that connects to the other nipple on the bottom of the throttle body

 

i am looking at this and it looks like its showing that the driver side iacv tube goes to where that nipple is in the pic i just took today, so if thats the case it was right to begin with but then where would that other nipple go (first pic)

 

thats different than my d-series...a d16y7, i have the iacv on the throttle body, but what im confused with is it shows the nipple you first posted about below the tb on the top-left of this diagram, but it doesn't show what it connects to, so look up where you found this diagram for that answer....and also, you have coolant running into the throttle body from the iacv, there has to be a cooland return line....my guess, and like it is on my y7, is there is another nipple right next to the one on the underside of the throttle body, and that is what connects to the other nipple on the long coolant stem that is with the labeld diagram "radiator lower hose"

 

idk, what if i just do it how the diagram says, then just cap off that one nipple in the first pic? can i technically break anything? knowing my luck it will f up my idle or something

 

look on the bottom of your throttle body and see if there is another nipple that doesn't have anything on it

 

you mean the FITV? yea, there is a hose coming out the back of it, one is going to the IACV i believe, i will have to check in the morning. and the other end of the FITV goes to a nipple connection in the head

 

can i cap that connection off or not? anyone?

 

oh well i capped it off
