CAI install help
99 tl aem CAI. The stock air filter has two hoses running to it. I disconnect both and loop one back to itself? Coolant lines right? Bc I have Antifreeze dripping around.
Second question. Noticed this tube near the battery ground. Did I rip it out of somewhere. What should I do w it. It is comig out of the lower frame and is dis attached

coolant lines were previously attached to the air filter box
can you confirm this loop back it okay?
this is the hose that is loose and I have no idea what it was attached to.

Really? shit. The stock intake has two lines running to it and from it. So I took off the stock intake and one of the lines, and looped the other.
stock intake 99 tl
stock intake 99 tl

All the lines stay on the car! Here's some pics I tried to take. Almost 10pm here so they're dark.
This is on the firewall side of the intake, vacuum line:
This is bumper side vacuum line connected to rubber flex fitting:
My intake is already on so hard to see the coolant loop but note that the bottom "nipple" on throttle body has no hose connected:
You should take the line from bottom of TB that points out towards the fender and the one on the side pointing towards firewall and connect these. They have the brass fitting between them. Hope this helps a little.

Omg, you hooked up the coolant line to the PCV intake. Do not start car with that.
The 99 TL sure is a weirdo, I didn't have any of those lines on my air box.
What brand of CAI is this? You shouldn't have to mess with those lines, just unclip them from the air box. Zip tie them somewhere else. If this is an AEM or other professional company CAI, it should come with ALL hardware and instructions.

Yea my intake didn't have the coolant bypass, mine came with my spacer set. Since we're talking intakes, has anyone done the relocating of the IAT sensor to the rubber flex hose on intake?? If so can you show a pic? Instructions are bad quality pics like they're photocopied.

"Coolant lines are on the throttle body"
" It shouldn't attach to your throttle body at all when it's done"
Do they attach or not. I know not to attach to the intake but there was previously a line that ran from the bottom of the TB to the stock intake and then out somewhere else. Since the stock intake is gone, do I just keep the line that is in the bottom of the TB and bypass the stock intake and connect it to the other line?
" bottom "nipple" on throttle body has no hose connected:"
"You should take the line from bottom of TB"
wait should I have a line on the bottom of the TB or not?
And can someone please tell me what in the world is that small line sticking out?
Thank you for putting up with me

If you are bypassing the coolant into throttle body there shouldn't be any coolant hose connected. Remove hose from bottom of TB on connection facing same direction as throttle body and then remove hose from under item 2 in this pic they both go to E-15-10. Second pic shows E-15 is a coolant hose just for double checking sake.

Can you help me understand why to keep the nipple on the bottom of the tb open w no hose on it when there is already a hose in it (this use to run to the stock air filter box).

To update, it is a AEM V2. The part and manual is for 2000-2003. I have a 99. I was told this wouldn't be a problem. But as you are probably aware, the directions in the manual are not helping me right now.
Is this loop correct?
Any idea what this loose hose is?
(ugh, photobucket isn't working now and imageshack won't rotate.)

To my understanding, my old setup had a coolant line to the bottom nipple of the TB that faces the fender, and I should keep it as so (just looping now). But Dave states he his "bottom "nipple" on throttle body has no hose connected". How is that okay?

connect hose 1 and hose 2 if you want to do the throttle body bypass
hose 1 shouldn't connect to the TB and hose 2 would connect with the block to the end of hose 1 that came off the TB side.
if you don't want to do the coolant bypass on the TB.. then hose 2 should connect from block side to nipple facing drive side on the throttle body.

i'll be honest.. i have no idea what that valve (#17) is for..
but here.. i made two lines on this diagram...
i'm guessing the AEM V2 lets you reuse the stock breather pipe.. but here
-blue line for throttle body coolant bypass (i drew it so that it avoids heating up the breather pipe as well.)
-red line to keep coolant passing through throttle body.

Bypassing the coolant in the TB goes along with the concept of the CAI. You want the air entering your engine as cool as possible. Cooler air is more dense than hotter thinner air therefore you'll have a higher volume of air present of its cooler. Rerouting the coolant away from the throttle body is another method of lowering incoming air temps. You won't notice a difference really but on really hot days your car will run as if it was cooler out than it really is an that's what it gets you. I say do the bypass.

Why would coolant bypassing the TB keep the TB cooler? Wouldn't it cool it when it connects to the TB?
I'll do whichever one I can figure out first so I can use my car again. When referring to my pictures, can you confirm I successfully did the "red line to keep coolant passing through throttle body" option.

Both good points to my question, duh. A lot of this is embarrassing but I wasn't born with all this knowledge and I want to learn. I just don't have anyone to show me mechanics so I'm trying with what I have (you patient guys and the internet).
Do I have this down yet?
Green is coolant coming in to the TB. The "this is what" is the coolant coming out of the TB?

Gotcha, I forgot to draw a hose, but there is one coming off of the bottom (this is what) nipple
1. Well going back to post #4, given there are two ways to do it, I had it right, correct? I was okay to drive last night?
2. So I could leave it as is. Or I could take the hose off the black box (in) and take the hose off the black box (this is what) and connect them, correct?

Thanks you! Had enough of me yet?
I asked b/c someone said "It is wrong and my coolant line to the PCV intake" which I don't think is true or showed in that in the picture. And someone else mentioned I looped it wrong.
Now I need to find out what in the world that small hose stick of the of the bottom does.

Alot of Information!
1.- The Stock Radiator on the TL-P Filter Box WARMs the AIR entering the Engine in Super Cold Days (Below 32°F) to make the Engine Warm FASTER that is its sole Porpuse, If you live in areas without Snow then you can Delete it + the Throttle Body Warmer too...
2.- That "Loose Line" in here, Its the A/T Trans Breather Tube that little fella goes nowhere it just allows the Transmission to breath out its fumes when its hot.. But also Allows Fluid to Puke I advise anyone to swap that little tube with a longer one to avoid Fluid to Leave the transmission! Been there, done that! and some other Aziners too:

Thanks again for everyone's help.
So I noticed that some water come through a bolt that grounds the headlight wires (which I tighten) and some water gets under the hood. Both conveniently make their way down to fall on the air filter.
I also noticed that the opening in the guard is right where the airfilter sits, prone to water?
