YES i have seached. so please chill. i purchased a S13 sr20det with freddy intake manifold on it. I don`t know which and how the coolant lines are supposed to be hooked up to the IACV and throttle body. I have a feeling the guy i purchased the motor from looped the coolant lines so that they wouldnt have to travel through the throttle body or IACV. Can i leave them this way without TB or IACV being connect? If not any help on where the coolant lines on throttle body are supposed to hook up to and the lines on the IACV? Ill have pictures up soon.

Well, its quite simple. The Idle control is NOT hooked up to coolant. The IACV is hooked up to vacuum at the rear of the manifold, and then in front of the throttle body.

Your pictures are horrible. But if the coolant is looped leave it looped.

Yes you can run the car without coolant to the throttle body. You "can" run the car without an IACV if you adjust the idle via the throttle plate; IE cracking it open making your static idle higher. However your car will be a bitch in cold weather.

KoukiMonsta

that is NOT TRUE. IACV has coolant passing through it, along with TB.

your pics totally suck

loop TB, just run 2 lines thru IACV, direction doesnt matter.

for a daily driver you need the coolant lines connected. I forget which but one of those two things has a wax element that expands or contracts with temperature and changes idle speed.
check the FSM it tells you all about the wax.

Sorry for pics being shit it's hard to get a camera down there while the motor is in the engine bay. Ill try and get better ones today. But from what some of you are saying just loop the throttle body. I will try and do the IACV as winter in North Florida believe it or not it can get really cold. When I do that I'll take pics just to make sure I'm looping them properly.

No, you didn't search.

Here: http://zilvia.net/f/tech-talk/499765...old-hoses.html . I just capped off the throttle body coolant feeds with 5/16" vacuum caps w/small clamps.

If you have any other questions, let me know.

I know this is an old thread. But! Awhile back when I was throwing my engine together I bought the s14 water neck to keep from having coolant lines running behind the block. WELL that also meant I had no coolant running to my IACV. We threw away all the s13 metal lines that give me the ability to hook up my iacv to coolant. Can I try to run a t piece from the heater core lines to the iacv and run it like that? Or do I need to get the under intake metal hoses? I cant find them anywhere.

if you need a set of the metal hoses, I have spares. if its easier for you to just add a tee to the heater core lines, go that route.
