in the context of this thread, what would cause the engine to lock-in at a higher temp. initial assumption is that the gauge is too inaccurate to be trusted. what if the tstat stuck closed? would the engine find a higher steady state temp (engine bay fan cooling, etc.)?

First place I would look would be how clean are the radiators, we often find literally pounds of crap (leafs, grass, paper, even a dead bird or two) between the AC units and the radiators on these cars.
