There are probably hundreds of discussions already about this very same topic. I dont think I have seen an agreement yet but if its all the way to the right there is probably a problem. These gauges arent the most reliable on top of it. Then consider that replacement sender units dont always work correctly as well. That being said, my brand new crate engine with a perfectly clean stock BB radiator and taurus electric fan never reads more than 1/4 up on the gauge. Everyone always suggests to use an IR gun to determine the actual engine temp.

If the cooling system is in good shape and working correctly it should run at the T-stat setting. I run a 180* stat to help with fuel percolation in the carb. and that's were mine stays 180*.
I'm not positive but the T-stat should be in the 195* range for your car.
Anything over 230* to 240* for any length of time is a concern.

Temperature of you engine's cooling system is dependent on many factors and whether the components in the system are doing their job: coolant mixture [optimum is 50%water/50% antifreeze], radiator cap pressure rating, cleanliness of the radiators fins [on the inside and outside], thermostat being used [180 deg. for best engine conditions; 195 deg. if you are "green"], condition of water pump, condition of hoses, and the age of the coolant. If you are running hot, the most likely problem areas are: bad thermostat, crudded-up radiator/engine, bad radiator cap, collapsing suction-side radiator hose, failing temp gauge sending unit.
