Glad you got that sorted out Ray. Isn't there an aftermarket switch you
could put on the radiator to turn it on, even if you aren't paying
attention? I could never rely on myself to remember to look at the gauge all
the time. Although as you say, they ECM doesn't seem to care if it's hotter
than hell. You could probably burn a chip to correct that, but I wouldn't
know how.
I think I should go back to a cooler thermostat too, just to make more
power. I also want to get those A/C lines to make that work again.
I think I've finally got the Camaro to run at a reasonable temperature.
