stock thermostat

What is the factory rating of the thermostat.
My factory temp gauge reads at the "M" in normal. I hear many people saying they switched to a 180 degree. I always thought and read in mags that 160 degree was the popular choice.
What should I get..180 or 160?

I know in the 87-93 cars it was a 195 stock, go with a 180. The 160 is too cold and doesn't allow the radiator ample time to cool the fluid before pumping it back through your motor, it could run hotter.

Hope that helps,

Rick
