Hey guys. Have a small problem. Since Im finally on vacation and have time to work on the car I tried working on my car last night but ran into a problem. Its been a year since I disassembled my motor and now I cant remember where all the coolant hoses go. Here are some pics.



Alright. The top right connects to the far far left (behind the engine) to the turbo feed line, correct? If so then the hose thats connecting the two has a outlet near the turbo feed line. Ok question is where does that outlet go?

Another question. In the far left the outlet goes to the heater core, yes? And it dont matter as far as I was told. Correct me please if im wrong.

Now the far right bottom is a small outlet that I block off or what? A few others blocked it off but others connected it to intake manifold?



That is the intake im installing and nothing is really the same compared to the stock. Does anyone have a coolant diagram?



Since now I know one connects to any of the heater core outlets what does the second one connect to??

That is what Im having trouble with right now and would really really appreciate some help right now. I'll provide some more pics later. Does anyone have pics of their motor out and has a pic of the intake side? I believe i could follow it.

back from the dead.. can anyone shed some light on this, we are in the same boat here with a rb20-s13 swap. Some of the Pics are down now, but... in the one pic above, i'm thinking the big one on right is for heater core inlet, left is heatercore's return to block..? The small one off the right side is to the turbo? The fsm seems to have no diagrams of this.. confused about the smaller lines, basically all of the routing on the manifold/Throttle body HALP! thanks.
