Go to a parts store and look up the thermostat for that car, that engine in the references that hang on the parts racks.

IF your engine calls for a "180 degree" thermostat the normal engine operating temperature range will be 180 +/- to 200 +/-.

Most emissions controlled (designed) engines run at about 190 - 200. Low temp thermostats (140, 160 degrees) lead to premature engine wear, moisture in cold oil, and poor fuel economy.

Update your profile to show your car, year, engine, maybe approximate location.

My 472 really likes it at 180 degrees...
