I would change it out for a 195... aka a new fresh stock one. Especially if the car has some decent miles on it and its never been changed. Most people dont change it till it fails completely.

It seems to be lacking in the proper open temp unless of course your temp sender is gone or inaccurate or the gauge is a POS like mine is.
