Thermostat

We are trying to replace a stuck open theromostat on a 2006 Chevrolet Cobalt SS Supercharged 2.0L Ecotec.

I was just wondering how to get it out, since the cam positioning sensor is in the way. Can you unplug it safely?

Also, any easier way to get it out, without moving around all the tubing around the motor?
