It looks like it comes out of the bottom of the motor, goes into the bottom of the radiation then the degas tank/bottle on top of the radiator tags into it.
I'm getting a little frustrated with the car.
The radiator did have a hole into so that in part explains the constant complaint light being on but everytime I went to add coolant the degas tank would be full.
I wasn't experience any over heating as far as the temp gauge said.
I have a new radiator, fan, coolant level sensor, and bottle just waiting on the water pump and radiator hoses.
