Re: '41 & '42 160 Temp Gauge Removal

I can't offer any more than has been suggested before. The gauges are mounted in pairs on plates which are fastened to the rear of the cluster. The plate for each pair of gauges has 4 screws holding it to the cluster. The temp and oil pressure gauges share the same plate and each gauge is connected to the engine by a length of copper tubing.
The plate will need to be unscrewed from the cluster and dropped down into a working position before the gauge can be removed from the plate. The copper tube and temp sensor bulb will need to be disconnected from the engine head and pulled into the drivers compartment before the temp gauge can be removed from the plate. The removal of the sensor from the head may be a project in itself if yours has been in the engine a long time. If it has I would suggest several liberal applications of PBBlaster or the like paying particular attention to the center opening where the tubing enters the nut. Start a day or so before beginning the project. Even with help the flange and sensor may be cemented in by sediment and will twist off the copper tubing
Since the oil pressure gauge is mounted on the same plate, if you want to completely remove the plate assy to a workbench in order to remove the temp gauge the oil pressure line will also need to disconnect from the engine and be pulled into the drivers compartment.
I can't speak to how congested the 41 dash is underneath or if it is worse than other models. I know on the 41-50 Clipper based models and actually on all postwar cars the gauges can be removed from the cluster without removing the dash or removing the cluster from the dash. While it is definitely not a pleasant job and will require some flexibility and dexterity, I would think the gauges can also be removed on a 41 without dash removal. Somehow I just can't see Packard forcing their mechanics to pull a dash which is a MAJOR project just to replace a gauge.
Here is a photo off ebay showing the 41 gauges. Note that the gauges are held to the plate by a single nut on each gauge. The nut has to be removed and then the gauge with the copper tube still attached is pulled thru the hole until the gauge and tubing clears the plate. Unfortunately the person that removed these gauges chose to cut the copper tubing making the gauges worthless without sending to a repair shop to have new tubing and a temp sensor installed.
