850 won't warm up! 850 1996

i have a 96 850T with 90K. I have had no luck searching for info on this, but this car runs extremely cold. Around town the needle might come up a little, but never to the "normal" middle range. Tonight (pretty cold night here) I was traveling on the interstate and it stayed down at the coldest part of the gage the whole time. The heat was barely luke warm. What is causing this?

thanks,

scott k

    A whole lot of posts about this on this forum...just look down the list. You have a bad thermostat...it's stuck open. Order a 87degree one from www.fcpgroton.com for about $8.00 and change it yourself. It's very easy. Your temp gauage should be at 3:00, winter at the coldest or summer at it's hotest. If it deviates from this, then it's your thermostat or your temperature sensor that is in the themostat housing. Most likely your thermostat though. You'll need a T40 torx bit that is 5 or 6 inches long to get past the fuel rail that's in the way on one of the screws. Just read the other posts and there is plenty of information.
    Good luck.
