________________________________________________
Summer`s here in Texas. 95 degs today. And I`m looking for a secon/third
opinion.
92 LT-1. Manual says thermostat is 195. Somewhere else I read 180, which
should only be the LT-5 engine, right?
With the factory installed thermostat it ran at about 200 degrees.
Originally, when it was a young pup it ran at 194-197.
Anyhow a couple of months ago I bought a 195 at Auto Zone, popped it in. Car
ran at 207-211.
Figured it was defective or mis stanped.So today replaced it with one that
is a 180. Tossed in water wetter as well. Car runs 201-207.
When the temperature shows 200 the guage is right smack in the middle.
Bad sensor?
The system gets hot fast at a traffic light. 215-220 in a few minutes. Fand
kick in at 228. The other readings were with a/c on (fans on)
Does anybody make a radiator that fits and works right in these? My 84 was
just as bad...

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.

You need to find out the `actual` water temperature instead of relying
on the guage/sensor. Get a remote digital thermometer with sensor on the
end of the wire...and strap it to the upper radiator hose while you go
for a long drive. Have the thermometer in with you so you can monitor
it. Or...strap any thermometer to the upper radiator hose which you
know is accurate...then take a look at it after a good run.
