Probably better to keep it in there. No thermostat would make the car take longer to warm up/reach operational temperature and hurt fuel economy.

Why would you drive without one? Your cooling system was designed with one in it. Without it, your car will take longer to heat up to normal operating temperature and the performance of your cabin heater and windshield defog will be decreased / delayed.

Edit. Nice Plain Jane. I should have refreshed before I hit submit.

I just always thought that a cooler running engine is a better running engine. Maybe just a lower temp thermostat is better. My Cobalt is always garaged so never needed the windshield defog in the mornings. I had a Saturn that the thermostat was stuck open and the engine ran cooler with no problems. Or course it was a different engine.

Thanks everybody for the feed back. Glad that I asked before trying it. Not removing the thermostat for sure at all.

Older carbureted engines didn't mind but they used to run hot in traffic anyway. If you take yours out it will take a long time to get to temperature.

It could even go into limp mode if all the ECM preset criterias aren't met.

Car is both the most efficient when warmed up as well as causing the least wear on itself in the proper operating temps.

A lower IAT is probably what you want.
