[T3] temp gauge

[Keith Park]

I WORSHIP my gauges  :-)  but with a boat in back you really do need them.
ALWAYS calibrate a temp gauge before you install it. You need boiling water,
your elevation compensated for and to apply the voltage the car supplies
when its running at speed for a calibrated number.  Gauges are indeed often
wrong but I did find that both my Faria oil temp gauges were in fact right.

An uncalibrated gauge is good for comparisons only, so make sure they are
telling you the right story.

Gene Berg has a bit of a rant about how poorly calibrated the temp 
sensors were. Since he couldn't find any brand that was reliably 
accurate, he refused to sell any. That's a responsible position to 
take, but perhaps a bit extreme. Even if they aren't accurate, they 
should still be able to tell you if something has changed.

I've never had a temp gauge, and never missed it. I've always found 
the sound of the engine, coupled with the situation we were in, was 
able to tell me how it was doing.

I DID have an oil pressure gauge for awhile, but in the long run that 
just seemed to cause me unnecessary worry, since it always read lower 
than I thought it should. The engine, however, never minded.
