Temperature gage says car is overheating. on 2002 Chevrolet Impala

Not over heating...cold to touch. Replaced thermastat, fan,and the waterpump. Cold air comes out of the vents.

Which engine is in the car? I think you have an engine problem instead of gauge trouble! I hope i am wrong.
On second thought never mind about the eng. size!
Good luck.
