So I filled up the radiator (took nearly a 2 liter bottle of 50/50 Dex-Cool/Water mix), started the car, made sure the radiator was filled to the neck while running and bleed out the air with the screw till the coolant came out of it. Tightened down the screw, checked the neck for coolant, capped it and rinsed the engine down so coolant wasn't sitting anywhere.

We shall see how this works, seems it was just low on coolant. Which is kinda strange cause it was just recently flushed & filled at my repair shop while they had to fix the 90* rubber hoses on the left side of the engine anyways. I guess I'll see if it gets low again, and see if there are any leaks at all. thanks for the help guys and hopefully this will fix the issue for now.

Next will be to replace the thermostat with a 195* or 180* since it's probably the original thermostat and I want to keep this car for as long as possible.
