water temps when using heater

Hey guys quick question,

What do your temp gauges look like when you use your heater on say a 40 degree morning? My stock temp gauge pretty much won't come off of the c unless I have been driving for at least a half hour, and the heater still won't get all that warm. It'll get noticibly warmer than say having it just bring in outside air, but its not toasty like my other cars. I'm thinking that my thermostat is starting to get lazy and may be sticking open. I seem to remember something about these t stats having issues like that when I worked at the dealer. On a hot day it'll sit at about halfway but on a cold morning with the heat all the way up it still doesn't get that warm.

What r ur thoughts.
I already did a coolant flush and switched over to zerex red.

It's been in the high 30's, low 40's here in the mornings. I get up to normal or near normal temps within a couple of miles. Thermostat is a cheap and easy fix. They do fail open. Be sure to buy OEM Ford replacement. Some 3rd party ones fail closed, which would be a worse condition.
