Its the item #11 that comes out of the thermostat. please help with a pic or anything that can help, i want to put my head back on today but i want to figure this out before i advance.

It goes in between # 8 and # 12

ok, i guess hte better question is what does 12 hook up to? thanks

#6 goes from the back of the head "goose neck" to the #8 which is a pressure bypass.

#9 goes to the bottom inlet of the heater core at the firewall
#12 connects to the upper heater core outlet and goes to the long T pipe (reservoir and lower thermostat)

#11 is the pressure relief hose that goes from the bypass to center of #12.

Euro cars never got that temperature/pressure relief valve, nor did early production cars. It was a recall, probably to avoid the possibility of a lawsuit if the driver allowed to the car to overheat to the temperatures for nuclear ignition and the heater core ruptured. I delete it as it introduced unnecessary complexity.

Sorry I was away for a while, here is wat I found, the bottom heater core is connected straight to the long t pipe for some reason, i also noticed that one of the ports was blocked on the throttle. I guess the PO deleted the throttle plate that keeps it from freezing under low temps. Now I'm more confused than ever lol can someone draw a little diagram or something of how sort everything out? Thanks guys
