The coolant temp sensor is on the driver's side of the engine in the head. If you remove the lid to the airbox and lift the intake tube, you will be able to reach it easily. To remove the connector, you just squeeze it. Then use a socket or a wrench to remove the coolant temp sensor. You will lose some coolant so be ready with the new one or drain the antifreeze before you start.
