Coolant temperature

Hi guys,
it has been very busy for me last couple of months and i havent got much time to drive my Grand Cherokee. It's daily driver for my girlfriend and last afternoon i noticed after 20 minutes of driving the temperature gauge was still showing 155 degrees. We live in Illinois and it's 35 F outside right now. I remember in summer the temperature was 210 and little bit more on hot days. Don't remember previous winters.
Is 155 degrees normal on this weather after 20 minutes or is it time to get new thermostat?

Mine is 210 or slightly less if I blast the heater all the time (even close to 0 F). I think you might need new thermostat.

When the thermostat is getting ready to die, you'll get some weird low and high temps. Mine died last year and it was during the winter. The engine wouldn't warm up enough to run the heater for a 30 minute commute.

Checked, thermostats started under $2
But are there any benefits using that JET low temp one?
