Numerical equivalent of temperature gauge range

[SMatson802@aol.com]

I have a ''71 spitfire that tends to run very close to the top of the 
temperature range.  It goes right up almost to the top, but does not get into 
the danger zone in any circumstance to date.  I am wondering if I just have a 
thermostat that is operating at the very high end of the range.  I think that 
it is a 190deg.  Would that put it at the high end of the gauge?
As always, I am expecting a variety of interesting, amusing, and enlightened 
replies.
