If you are talking about the temp sender, I have witnessed two removed. The first one was frozen so badly it broke the housing it was screwed into, and had to be pulled and sent to Onan for repair of the complete housing. The second one I told the owner what happened to the first one, and he took a couple of days putting penetration fluid and turning the sender both ways to try to get it out. About three days later it came out without any damage.
