The 3.8L does not have a CHT but just the engine coolant temperature sensor.
So, I will attach the info below that will help with this temperature sensor on this engine but here is a guide that will help with this:

Basically, I am attaching the location view of the engine bay that will show where this sensor is and then the process to replace it.
Please run through this info and let me know if you have questions.
Thanks
