Temp sensor located?

This temperature sensor appears to be on the top of the engine towards the rear of the compartment.

Take a look below at the info attached.

However, here is a guide that will help with draining and filling the cooling system as you are going to have to do this in order to replace this:

As for the sensor that is on the radiator, I don't show that as an option so I would suggest getting a picture of what it looks like and I am sure we can figure it out.

Please run through this and let us know what you find. Thanks
