radiator cap and ECT sensor

I am trying to change out my daughters coolant on her 2007 Mazda 3. Am I blind because I can't find the radiator cap on the radiator. I can find the cap on the resevoir. Is this it????

I also need to know the location of the ECT sensor. Any help on these 2 questions.

Thanks Bponb

Yup! That's it. None on the radiator itself as its a closed system. Pull the rad hoses to drain.

But I have to admit that I am not sure where the ECT is on these cars. 'Never had to locate or change one.
