[Tigers] Engine Temperature

[Dave Munroe]

Hi Stu;

That's an interesting and well researched article you've written. Pheeew, 
who knew those little gauges were so complex?

>From your research, you determined the accuracy is +/- 10F on the temp 
gauge. Interestingly, that is the degree of accuracy I found with my 
infrared thermometer. Being the anal type, I didn't like looking at my gauge 
reading 210F when the sender was sitting in a pool of coolant at 200F.
It kinda got me a little tense, particularly when my engine was actually 
hitting the boiling point and spewing all over my and others' driveway.

After I got my engine cooling under control, I needed, really needed, to get 
my gauge reading correctly, so I could relax in my Tiger, so I got my engine 
up 190F and tweaked my gauge needle to read 190F. Crude but effective. I 
have checked it several times over the past few years, and it is staying 
pretty accurate at 190F.

Likely it will not be accurate at other temps, but I am really only 
concerned with 190F, the temp I have been running my engine since cooling 
fixed. Now I am considering installing a 180F thermostat, so perhaps I 
should re-calibrate?

Dave
