I put a standard 180 Autozone thermostat in my 92 SE awhile ago and noticed that it run just slightly hotter than the older Stant 180 I once had. Still, it'* a cooler 180 stat overall so no harm is done either way regardless of what brand I guess.

Aren't these Autozone stats made by Robertshaw? They seem to have the same patented Robert shaw design which, by the way, looks exasctly like the Hypertech.

My old Hypertech said Radco on it.
