What brand thermostat. The engine should get up to temp regardless of outdoor temp.

Buy a better thermostat. Stant is good.

I have a stant 180 and a stant 195. I just put the 195 in until about May when I'll switch back to the 180. I get warm air with the 180. I get hot air with the 195, which is the factory temperature. So it might not hurt to go to one of those.
