With the drop in temperatures I started wondering if my thermostat isn't closing entirely. My prior car, a 2001 Maxima, as well as our big 5.7L Tundra all warm to operating temperature by the time I hit this one waypoint on the way to drop my son off at school. On my Focus ST, the heater has just started with warm air and the water temperature needle just moved off cold. As I understand it, our cars will throw a code if they think the thermostat is stuck open, but it is curious. Total time running at the waypoint is something like 10 minutes, light-to-moderate driving.
So my question is - how long does your car take to warm up when the outside temps are around 40F?
I'd hate to have to pull the thermostat and toss it into a pot of water to see where it opens, but...
