Did you replace and flush the antifreeze yourself? Maybe you have an air pocket in the system, did you try bleeding it yet?

You replaced the water pump and thermostat, but you dont know where the ect sensor is?
Either way, its located on the back of the water neck.

to bleed the system just turn the heat all the way up, open the filler cap (unless you have a bleeder crew somewhere) and fill it up, let it run at idle and every time it burps and drops the level top it off . depending on what your capacity is it could take anywhere from 10 minutes to and hour+. my BMW holds 4 gallons of coolant so it took forever.

Cool story, bro.

Edit: You seem new. Or at least have no idea how to help us help you. Look this shit up on google or figure it out. You havent even done the simple stuff to begin diagnosing the problem. Get back to us when you do.
