I never bothered to change the thermostat. I'd have to disconnect AC hoses for access; requiring evacuate and recharge. The code hasn't reoccurred lately, and if it does, I'll just clear it with ForScan. No performance issues; I'm in Tucson and rarely use the heat.

Sensible way to change? Access is very poor. I've been getting the P0128 off and on for two years, If I clear it with Forscan it stays away for a while. Just looking at the temp gauge, it seems to take a while to warm up. I'm just afraid it will re-occur when I have to go for emissions. Plus the coolant is old. I'm looking at maybe disconnecting the AC suction line.

Thanks for the long, thoughtful post. My 2010 is the same color! 232k, amazing.
