[AJD] Running temperature

[Bill Salisbury]

HI CEE VILL,

Thanks for your information.  I do appreciate your effort.  I still have the 
old thermostat and although it seemed to produce the same running temp, I 
will check it on the stove to see when it opens.

Regards,  Bill

The only time that would seem like a problem to me, Bill, is if I wanted 
heat from a heater core in winter, or if I was going to run kerosene.  It 
seems your cooling system is doing a good job.  If you work it hard on a 90 
degree day and it runs 20 degrees warmer, you are still in good shape.  I 
suspect the new thermostat starts to open lower than it is marked.  I have 
had to try three of them in years past to get one that would give me good 
heat in winter on some trucks and cars.  I have cooked them on the stove 
with a candy thermometer in the water to see where they really open.
