coolant and thermostat question, re-updated with a twist Options

[HaysoosKreesto]

Hey everyone, it's been a long time since my last post. Car still runs beautifully but my first ever problem arose that perhaps a friendly user might help me solve, or know of the page that solves it.

So my coolant has been boiling out of the reservoir after driving on the freeway and coming to a stop. I tried changing the thermostat, maybe the thermostat is defective? Well assuming it's not (I do plan on going back to the dealership and asking for a new one in exchange however) perhaps it may be something else. Does anyone know where the sensor to monitor the temperature of the coolant before the radiator fan kicks in is?

I'm having trouble searching for it, but I figured that if I change the sensor and the thermostat (again) then maybe my problems would be solved.

Also if anyone has any idea as to why it continues to do this, with all appreciation I urge you to please respond.

Thank you and much love,
Rafael.

Edit: check last picture to see the new situation

If it's like the 7A it'll be on the driver side middle of the engine. It's in the general area of where the coolant hoses that run to the throttle body are. Though if it were bad I'd think it'd throw a code. It could perhaps be a blockage in the cooling system somewhere.

+1, For the 5sfe. We have the coolant temperature sensor, engine coolant temperature sensor, and the fan switch. The fan switch is screwed under the radiator on the passenger side right next the drain plug. Easiest way to find this one is to follow the bottom radiator hose from the engine to the radiator. The other two are located right next to each other. Follow the upper radiator hose and right when it hits the engine. You'll see two sensors. The bigger one which is on the passenger side will be the engine coolant temperature sensor and the smaller one which is on the driver side would be the coolant temperature sensor.

BTW, it seems like you're having overpressure so what I would do is perform coolant flush. Flush out the radiator and the engine block. Also check your radiator cap make sure it's at the OEM specs. I think the 5sfe was 13psi? All I know is it's 0.9 on the cap not the 1.1 like on the high performance caps.
