I have just relocated from Florida back to Michigan!

I had my Grand Prix 2005 N/A shipped on a truck. It has been cold these past few days (30's) and I took her out for a drive.

15min into the drive I notice low coolant temp and then engine light P0128. I have a 180 thermostat since Florida was so hot.

I assume the code is because of the 180 stat, should I put back in the 195?
