Technical Help! Engine overheating!

[BeerThePanda]

Hi, I’m at a loss. My Panda started running VERY hot since two weeks, and I’ve no clue why. I’ve always maintained her as best as I could, since then I’ve: replaced my head gasket, replaced all fluids (no significant discoloring), replaced all radiator hoses and the radiator itself, and replaced the spark plugs & carburetor. Now it still overheats AND has a little knock I never noticed before (video attachment). My only thoughts are that the timing chain might be worn? I’ve removed the oil pan and it looks fine.

Any and all tips are greatly appreciated, mainly I want to fix my panda, keeping a budget would be nice but I’ll do whatever’s necessary!

Thanks in advance

You've not mentioned the thermostat?
