Do you have an updated guide for replacing the thermistor? My MK3S doesn't look much like this illustration/photo. The extruder looks different, as mentioned in the previous comment the unit uses split wrap not spiral, the tywraps are in different locations. In short this isn't much help. I also (after loosening the screw) cannot get the thermistor free from the heater block, despite pushing on it with the hex key and the tip of a pair of needle nose pliers.
