So heres the deal, Its been so long since I have had this motor together, I kind of forgot where all the heater and cooling hoses go. The head is a k20z3 head. (my description is as if you were looking into the motor from the front of the car.)On the intake, there is a port on the top of the intake, right hand side. It goes to a port underneath the motor, and attaches to the back of the thermostat. There are two hose that appear to come out of the thermostat, and they dont have any hoses on them now. Could someone please take some photos of their setup, )k20z3) and let me see how i ma supposed to route this? I will upload pics of what i have later

might be better off searching around on 8thcivic.com. Take a look in their engine bay pics thread or something

i know one side goes to the lower rad, one to the head, but forgot the other one, but i think you sohuld be ok just running the one to the head for now until you drop the motor in and see what needs to be done. i honestly think its connected to more heater hoses though

EDIT: one goes to heater hose pipe and other to head. bottom to lower rad.

this is where the AAV goes. the upward nipple goes into the intake manifold by the VC and the nipple pointing parallel to the ground goes to the intake tube.
