Hey all. I've slowly been learning my way around my car and was always suspicious of the coolant piping coming from my AAC - it just looked wrong. And, it turns out it is - this picture is of my current setup. Notice the 3rd line has been blocked off.
My questions are as follows:
1) Why would someone do this?
2) Where is the first line meant to go exactly? I deduced from other threads/images that the middle line goes to the throttle body (currently my first line does) and the 3rd line goes to the manifold (currently my second line does), but I can't figure out where that 1st line is meant to go to.
If there isn't any obvious reason for this set up I would like to reroute the lines to their usual spot. Probably unrelated, but I stall after revving and have idle issues, and I know this coolant affects an air flow valve hence my interest.
