The first thing you really need to do is find the cause of your coolant lose--- overheating issue.
Until you know the true cause of the problem you could chase your tail and spend lots of money replacing parts and buying coolant needlessly.

"The first thing to do is pressure test the coolant system to see if you still have a leak."
That is actually a simple easy test. You just need a coolant system tester.
Harbour Frieght has them for around $90.00 I think it is.
you can pressure test the system and the cap.
Or find a shop that will do it.

If the system checks out then you need to find out if the water pump is faulty.
The fact that you heater does not work makes me think your water pump is faulty.

"But I am just guessing"

If you find that your water pump is faulty it is not going to hurt to replace the thermostat.
You could replace it with a low temp thermostat then the car should run a little cooler.

What is the code your getting???
