Are you EOC'ing during your drive? If you don't, then we must assume your cooling system is not working properly. If not, then you should try completely blocking the radiator, front and back, with cardboard to help with the heat retention. I believe Old Mech. mentioned this.
It's 20 degree's F here and with a complete grill block my radiator fan still kicks on several times on the way to work, that means 225F.
Why aren't you using a block heater??? I'm at 90-130 degrees by the time I leave in the morning, depends on ambient. I get to 195 in just two miles. I also use trans and oil pan heaters
