The sensor is not really "hard" so to speak. On the SS, it is not located in the best position for using tools, that is correct. Which is why you'll have to unscrew/rescrew it like 5 degrees at a time and hopefully you can slide your hand through some things so that you can grab it with your fingers.

If anything, it's frustrating in my opinion. Maybe I just got lucky, but I didn't really have any problems with it other than 5 degrees at a time.

 

IT WORKED!!!! WOOO!! I am so excited. I took off the top radiator hose first and when that was moved out of the way the sensor was right below it and super easy to get to! Took me about 45 mins to get everything all on and together. Started the monte up and waited about 10 mins and the temp. gauge went straight up to normal, and, since I got a new thermostat, the air was finally hot..Probably should have done it before winter hit instead of after..lol

 

Glad to hear that your problem has been fixed!
