Hi and welcome to 2CarPros. Lets see what we can figure out for you.
I understand you have changed the water pump and thermostat but I have a few questions for you.
1: Is it over heating all the time or just sitting still while not moving?
2: When it starts to overheat is the cooling fan coming on?

Here is a guide on the cooling system and how it works so you can understand the system which will help fix it:
