Thermostat bad?

Shiza · 12-29-2018, 04:55 PM

Hey guys, so I know it's colder out but I've noticed that my car is not reaching 210° while driving.

For example today ambient temps were 44-ish. On the 30 min drive my car would only reach around 190° while driving at highway speeds and 200 when stopped in traffic.

Is this normal for colder weather or is there a chance my thermostat is stuck open?

normal operation for colder weather

Definitely normal. I'm in MD too and I'm normally in that range coming home from work on 495.

I don't hit 210 unless I'm in stop and go traffic.

I'm in SoCal and the coldest it's gotten is 42. During this cold weather while on the freeway I'm around 190 as well. It's always done this in my 5 years. In traffic it gets up to temp still lol.
