What year and engine is in it?

1994 with 5.0 is it possible it needs a flush job or possible temp sensor issue ? thanks alot for the assistance!!

I would think the coolant temp is actually warm because the engine produces heat. The gauges are likely a sensor issue you have two sensors for the heat one for the gauge and one for the computer.
You could have a plugged up heater core. you can check this by pulling the hose off the heater core and checking if you have flow in and out of the core.
Have a bucket ready to catch the antifreeze.
