[QUOTE="shurur, post: 11739061, member: 113850"] Heater core return goes back to the pump I think. Those back freeze plugs (or at least the 7/8 driver's side head) should be brought to a T put in to the front of the upper radiator hose to get (some of) that that hot back head coolant to the radiator when in open loop. I think as It is now..you're feeding the closed loop (engine heating) system-cycle-configuration constantly (in a sense) by not allowing coolant to flow forward through the heads to the bypass where it will go closed loop or open loop back into the radiator for cooling...depending on the thermostat. Moving some of the Hot coolant through the heater core and back to the pump and though the engine again isn't going to help you much...and maybe hurt because it could have gone thruogh the heads forward to the bypass and on to the radiator for cooling. If you're going to steal/theive/create-a-feedback-loop to the input with a little hot coolant from the back of the head ..I think you need to get it to a Tee in the upper hose to the radiator bypass tube (direction depending on the thermostat position).....a little hot coolant needs to bypass the heads, but go in the the same direction it goes in the heads....back to the radiator for cooling.
