Skunk2 ectra coolant line on b18c1

after reading tons of DIY’s i still can’t figure out what the extra coolant port goes to, and i don’t have any more lines that i can hook up to it. I put coolant into my car yesterday, and there is the small coolant port that comes off of the skunk2 manifold, that my stock gsr manifold does not have,
I can’t figure out exactly what it is, or what to do with it.

Get it done yet…lmk. I’ve got it covered. It’s late right now so I have to check it out tomorrow morning

Ok. Small tube right. It goes bottom of vtec solenold. There should be another small tube somewhere there. Extend it since the stock gsr already had the metal tube that ran it with the intake tubing together.

Well I’m using my stock ls throttle body, as there is a port on the bottom of it that the coolant line I think you’re speaking of goes. That’s the thermometer that passes coolant through the throttle body. I just have the hose clamped off right now
