Anyone done this without draining the system completely just to change the thermostat itself or the Engine Coolant Temperature (ECT) sensor?
Car through P0128 code, thermostat malfunction, and needs to be fixed in order to stop Service Engine light from reoccuring. Reference my post here for more details:

If so, please provide some details/insight and Part #'s (can't find them anywhere) if you can and any pictures if possible too! TIA.
