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.

You might help it a bit with a
Hypertech PowerStat...
The PowerStat will flow more water that any PepBoys or GM Stat
while still controlling temp..
But it`s not too far off what the factory wanted it to be..
I have a `94 LT1 and it stays at 180-185 in the Florida heat and humidity
with the PowerStat and the HyperTech Programmer.

Title: Tuning: Mansory CYRUS based on Aston Martin DBS or DB9
Date: Thu, 24 Sep 2009 12:15:13 +0000
Author: Trance4you
Mansory tuning house presents the Cyrus aerodynamic kit for the the Aston Martin DBS or the DB9. The Cyrus emphasises masculinity and power with the carbon fibre wing extensions, newly designed rear skirt with the integrated diffuser and provides space for four stainless steel and pipes of the sonorous sport exhaust system.
The two slotted right domes on the carbon fibre bonnet send extra air into the 12 cylinder engine. The car squats on large 9×20 front and 10.5×21 rear specially-insincere striking rims wrapped in 255/30ZR20 front and 295/25ZR21 rear Dunlop Sport Maxx tyres. The coilover suspension has been adjusted to lower the centre of gravity and upgrade street property for providing the best road holding.
Read more (details and photos)!!
Mansory’s definition of luxury extends to the interior where tailor-made carbon fibre parts are found. They involve some bits from the console, the centre console and the re-designed steering controls. Foot gearshift was made of aluminium while the door sills and head rests feature embroidered CYRUS logos. Hand-stitched leather covers the seats, parts of the dashboard and inside the door panels.
