So it took me two days to essentially figure out the overheating issues were caused by a worn out water pump and that I didn't flush the coolant enough, I will be flushing out the store bought coolant in favor of OEM coolant and replacing the thermostat. I might need to keep the old thermostat just in case the new one turns out to be faulty, In the meantime I also had a look in the valve train to see why my timing chain is rattling everytime i start the car. 
Every component in here looks like it has normal wear and tear but the rockers are fine and there isn't anything loose. I shined a light down the timing chain and saw that the tensioner was well worn-out at this point. It didn't help that the engine wasn't ran for a month thanks to the ecu fiasco.

It was like 6am when i took these photos, However i ordered new gaskets and a tensioner kit plus other stuff so that will be on it's way.
Here's the part numbers for the window crank and it's components:
Window crank is 51321904507
Window crank washer is 51322460567
Window crank cover is 51321906497
The screw for the crank is a T25 Bolt that screws in the middle.
I'll update with a guide on replacing the tensioner once it gets here. Cheers!
