Alright the plan is to put the temperature sending unit in the driver's side hole, the heater core inlet in the passenger side hole, the heater core return to the water pump, and the external bypass from the 3/8 NPT fitting at the front of the intake to the 3/4 NPT fitting on top of the water pump - this should provide adequate cooling until the thermostat opens, correct?

Thank you all for your replies
