lower temp thermostat should make your car run cooler. The only thing it is going too change is often your radaiter fan comes on.

 

Going to a cooler thermostat makes the engine's computer think that it's running hotter. The thermostat is what reminds the engine that it needs to cool itself. There is a range of temperatures that your engine will run most efficiently. Running too cool and you risk losing some of that efficiency. A 160 degree thermostat isn't all that suitable for colder climates, but a 180 degree thermostat will serve you just fine.
