Just took the Taurus for a nice spin out through the State Park next to my house. While coming home -- engine light illuminated. First time this has happen in the year plus of ownership. Code -- P0125 on my code reader. Popped hood and coolant is at proper level. Noticed it barely blows any heat and takes forever it seems for the temperature on the gauge to rise??? Runs normal besides... Cleared code but wanted to put this out there.

appears to be a stuck open thermostat most likely.

IIRC the vulcan was abit easier to work on than the duratech in those.
