I rebuilt the gas line for the temperature gauge a 34 Chevrolet last week - the fellow was putting it back in the dash when the old line fatigue cracked on him. I spliced a new line in and tested it by putting the bulb in boiling water - it registered 190 degrees max. I was concerned that I had let some of the gas escape, so I put a new line in with the same result. I realize that Packard gauges have to be better than Chevys, but the moral of the story is test the little boogers before you take the indicated temperature as gospel.

I've had temperature gauges bounce all over the place before after I'd changed fluid. This was caused by having air bubbles/pockets in the block. Drilling a small hole (1/16" will work) in the thermostat before installing it will usually cure the bubble problem.
