Hi:
Have you had the radiator and the heater core flushed?

Hi:
That is where I would start. If you replaced the t-stat, something must be blocking the coolant from circulating. At least have it checked by a mechanic to see if that appears to be the problem or check the radiator for circulation yourself. If you need directions, let me know.

Let me know how this works for you.
