There are 2 coolant sensors; one is mounted to the bottom passenger side corner of the radiator, one is mounted at the back of the cylinder head just under the intake manifold.

If you need to change the coolant temp sensor on the head, you'll need to take the intake manifold off to get access to it.

I highly recommend you purchase a Bentley manual for your vehicle.
