`You do not have a problem. They are designed this way from the factory.
The fans are supposed to stay off until 228F when the A/C is turned off.
What you are seeing is exactly what is supposed to be happening. From
what I have heard, this is supposed to help fuel economy and emissions.
If you do not like it to run this hot, you will have to change to a 160
degree thermostat and get a Power Programmer to change the computer`s
temperature settings.`
ME: Ive seen a kit which will turn on the fans sooner for this
generation vette . I think Mid America has it in their catalogue.

Exactly what I was going to do, but way too hot and humid here today to even
think about dinkin` with the car. I did look at the temp reading while it
was "cool" (relative term) in the garage. Thermometer bulb in coolant tank,
read 103, display inside read 103.
And while this 180 deg thermostat is reading about 7 degrees lower than the
195 degree one did, something tells me that something is wrong. Unless the
sensor is just plain flaky.
What I couldn`t find definitively was which sensor runs the inside digital
diaplay. Is it the same one as the gage? And is it the sensor on the front
of the engine around the water pump? Or is it the one on the side of the
block?
I don`t think I have a pump problem, you look in the tank, and pretty
intense jsts of coolant flowing.
Since the coolant flow is "backwards" in the LT-1, could the blister packed
thermostats from "the boys" be not right?

George, Cant help you with the questions about the LT1 sensor location,
etc...
Try a `balanced` type thermostat for your car ; these are much more
accurate than the cheap $5 ones from a store. Pep Boyz has them as does
Summit and Jegs mailorder. Stay away from RObershaw Brand...i put one
in and it stuck closed on me....my aluminum heads reached over 250
degrees before i discovered i had a problem.
