It flows out of the upper hose, through the radiator, and then back into the edge via lower hose/thermostat

For the rest of the cooling system flow, check the FSM, I don't recall off hand.

Th OEM cooalant temp sensor is in the same housing that the thermostat is in. This obviously works for OEM cars. I personally put mine on the upper hose/head outlet side, to get an idea of how warm the car actually is once it hits the radiator.

I used a CustomSteel coolant adapter (Home)
