Overheating B18 🇸🇪 Volvo Amazon 122S (VotD Feb18)
UPDATE 2018: The aftermarket radiators and fans never work as good as a used OEM that is DESIGNED for these cars. I swapped in a used OEM rad and fan in 2017 and, while it gets warm in traffic, it runs cooler overall and doesn't overheat like this.

A few clips from the various things I've been trying on my B18 overheating issues. I also read about the thermostat discs that block off the engine recirculation and make the coolant flow exclusively to the radiator. That is my next place to look when I get a chance to compare thermostats.
