Did you bleed all the air out of the cooling system? Does it only run hot while at an idle but cool down as you drive at highway speeds?

When you first start the car does the gauge start at cold and slowly rise to hot or does it jump straight to hot? Are you sure it's actually getting as hot as it says it is?

Ok sounds like gauge is operating properly. Double check that all air is out of the system and that the system is full. Also inspect top and bottom radiator hoses. Does one of them look kinked or sucked flat?

Have you ever added anything like stop leak to your coolant? (Fix in a can). If no then I feel 2005 car to new to have to have radiator replaced. Was thermostat installed correctly?

I will look at the hose again .Not sure if the thermostat was installed will check that again

If all that checks out you might just have a head gasket issue. These cars are known for blowing head gaskets.
