Re: 1942 Model 2055 "160" no temp reading

Looking at the layout of the 40-42 conventional body instrument clusters I believe it will be the same as others except the instrument pairs are mounted in a vertical instead of horizontal orientation on the 42.
If the temp gauge has not been removed from the head in quite some time, I suspect the bigger issue is going to be removing the sensor bulb from the head without having it twist off. Rust, corrosion, and sediment can absolutely cement it in place. Use ample penetrating fluid on the nut threads and in the center where the cable enters. If it hasn't been out, I would suggest letting it soak for a day or so replenishing a couple of times before attempting removal. Can't say for certain on your head but if like the 47 356 head, I believe the threads for the sensor nut will be 5/8-18. An ordinary bolt found at the hardware will plug the hole if you need to have coolant in the engine while the gauge is out for repair.
Once the sensor portion is removed from the head, the bulb and tubing is pulled thru the dash ready for the next step. The instruments are held by mounting plates which screw to the cluster. On the Clipper the temp and oil gauge are together but I don't know if that is the same with the 160. At any rate, the wiring to the other instrument sharing the mounting plate will need to be disconnected and the mounting plate will then need to come off the cluster. A screw at each corner holds it to the cluster.
Once the plate is off then the temp gauge can be separated. It is held by a large nut. Once that nut is off the temp gauge should be free and tubing can be pulled thru the mounting plate and gauge sent off for repair.
Here is a Clipper orientation showing the back of cluster and how the gauge is mounted. It is the horizontal arrangement but suspect the 42 160 is the same with instruments on top and bottom instead of side by side.
