You have got a 190 degree thermostat in your car if you put a 180 degree thermostat in will it run cooler?

A low-temperature thermostat will not prevent overheating so much as delay just a little bit. It will also cause poor fuel economy and with most electronically controlled FI systems, it will cause fuel control errors.

Answer

If the engine is overheating with a properly functioning 190 degree thermostat, a 180 degree thermostat shouldn't make that much of a difference. Make sure the existing thermostat is working properly, make sure the radiator isn't blocked or partially blocked, and that the cooling fan and water pump are working.

Answer

A computerized car needs to have the thermo specs call for.

Changing the engine temp can alter the comp readings which can cause bad running, high fuel usage and costly repairs later on down the road.
