Would a 396 Chevy run cooler with a 160 or 195 degree thermostat?

Theoretically it would run cooler. The temperature rating on a thermostat tells you it's fully open position. So when the coolant temp reaches 160 then coolant will be allowed to flow to the radiator. Where as the 190 will open 30 degress warmer. And generally a lower temp is better. Just make sure you replace it with the OEM for the winter... or your engine won't warm up enough when it's cold.

Probably a 195 (F) degree thermostat. That would be what the system is designed for.

It would depend on the degree thermostat installed, probably 195 degrees F.

Yes, given that there aren't other issues with the cooling system. Is the fan in good shape? Is the fan shroud in good shape, or even there at all? Has the cooling system been flushed recently? If all of these things are in good working order, then yes, a 160 degree thermostat will obviously run cooler than a 195 degree thermostat will. One more question... Is the radiator big enough? That is the next question after you have eliminated possible problems with everything else.

It would have a 195 degree thermostat so it would be in that range.

Engine will run coolerIt may be less fuel efficient if the factory design requires a 195The heater would not be as warm.Engine will run coolerIt may be less fuel efficient if the factory design requires a 195The heater would not be as warm.
