There are two coolant temperature sensors, one is in the radiator and the other is the rear of the cylinder head held in by a clip and then pulls straight out. This is not bad to do if you remove the hood, which is easy if you have two people. Just mark the hinges before you begin. Also, drain the coolant from the system. Here I the location of the coolant sensor behind the cylinder head and radiator in case you need it. Check out the images (below). Let us know if you need anything else.
