Could be the t-stat. Could be bad temp sending unit. I would start with t-stat and while your at it, flush your system well. Good Luck!!

I agree. Most likely the t stat is stuck open. I just had this happen to me and mine was running way too cold and had barely any heat. Replaced it and runs just under 210 and I have heat! Do a flush like the other guy side while your at it.
